{{quote|Gee, it's only the best castle ever made! Take a look from a distance! Powerful and awe-inspiring design choices slap your face! It's like looking at me!|Bowser|Mario & Luigi: Bowser's Inside Story}}
'''Bowser's Castle''' (or simply '''Bowser Castle''') is a recurring location in the [[Super Mario (franchise)|''Super Mario'' franchise]]. It is the domicile of the [[Koopa (species)|Koopa]] villain [[Bowser]] and the base of operations for [[Koopa Troop|his army]]. The castle's name, design and greater location vary from game to game, but the castle is usually a Western-themed castle and situated in a volcanic wasteland, and is characteristically an important base from which the Koopa King formulates his plans and summons his minions to take over the [[Mushroom Kingdom]] and carry out the capture of [[Princess Peach]]. Bowser's Castle is usually the final area that [[Mario]] and his friends visit to defeat Bowser and rescue Peach and is usually guarded by Bowser's most powerful minions. In the ''Super Mario'' spin-offs, the castle can serve as a go-kart course, a tennis court, a baseball stadium, etc., depending on the sport the game is based on.
==History==
===''Super Mario'' series===
====''Super Mario Bros.'' / ''Super Mario Bros.: The Lost Levels''====
Bowser's Castle first appears in ''[[Super Mario Bros.]]'' at the end of [[World 8 (Super Mario Bros.)|World 8]]. In [[World 8-3 (Super Mario Bros.)|World 8-3]], [[Mario]] battles [[Bowser]]'s forces outside of the castle, which can be seen in the background; in [[World 8-4 (Super Mario Bros.)|World 8-4]], Mario ventures into the castle itself, where he battles and defeats Bowser in order to save [[Princess Peach|Princess Toadstool]]. It is also the setting of [[World 8-4 (Super Mario Bros.: The Lost Levels)|World 8-4]] in ''[[Super Mario Bros.: The Lost Levels]]'', except is shown to be located in the sky at the end of [[World 8-3 (Super Mario Bros.: The Lost Levels)|World 8-3]]. Additionally, it appears in [[World D-3]] and [[World D-4|D-4]], where it is instead grounded. In ''[[Super Mario All-Stars]]'', Bowser's Castle is easily distinguished from the other [[castle]]s by having thunder and lightning flash in the background.

{{main|World 8-Bowser's Castle (Super Mario Bros. 3)}}
In ''[[Super Mario Bros. 3]]'', Bowser's stronghold (as well as Bowser himself) is not seen until the very end of his kingdom, [[Dark Land]] (which is also called "Bowser's Castle" in later remakes). The mentioned [[World 8-Bowser's Castle (Super Mario Bros. 3)|castle itself]] is one of the longest levels in the game and is where Bowser is keeping Princess Toadstool captive. The map icon is animated in ''[[Super Mario Advance 4: Super Mario Bros. 3]]''. It is also the only actual castle level in the game.

====''Super Mario World''====
{{main|Front Door}}
{{main|Back Door}}
[[File:SMW Bowserscastle.png|thumb|left]]
In ''[[Super Mario World]]'', Bowser's Castle is found in the [[Valley of Bowser]]. There are two ways of entering the castle and many ways to reach the end of the level. There are two main corridors where Mario or Luigi will have to choose one of four possible doors. The player can also reach the Castle by using the [[Star Road (Super Mario World)|Star Road]] that leads them to the front gate, bypassing the rest of the Valley of Bowser entirely. To get to the back gate, the player had to find the secondary exit in [[Valley of Bowser 2]] and go through [[Valley Fortress]]. This takes the player straight to [[Back Door]], skipping most of the level. The castle itself featured a neon sign with Bowser's name spelled out. Bowser is also seen flying in the background of the castle in his Koopa Clown Car, albeit in silhouette during occasional thunderclaps and his eyes glowing in the darkness otherwise. In ''Super Mario Advance 2'', he is absent entirely after the level is cleared.

[[File:Bowser Castle NSMB.png|frame|left]]
[[File:Bowsercastlensmb.png|thumb|Bowser's Castle in ''New Super Mario Bros.'']]
In ''[[New Super Mario Bros.]]'', Bowser's Castle is relatively similar in appearance to the one in ''[[Super Mario World]]''. It is found rising out of a lake of lava and is at the end of a twelve-level-long path. Once inside, Mario/Luigi will encounter [[Thwomp]]s, [[Dry Bones]], [[burner]]s, as well as [[Lava Bubble|Podoboo]]s. The ? Switches in the castle have an unusual effect; once pressed, the gravity of the castle will invert and the Player, along with any enemies (excluding burners) will have their positions inverted. The second part of the castle is a looping room, similar to Worlds 4-4 and 7-4 of ''[[Super Mario Bros.]]'', with lots of lava, a single Podoboo and a single [[Fire Bar]]. Once the final boss door is reached at the castle's end, the Player will have to battle both [[Bowser Jr.]] and [[Bowser]].

====''New Super Mario Bros. Wii''====
{{main|World 8-Bowser's Castle (New Super Mario Bros. Wii)}}
[[File:NSMBW Bowser's Castle World Map Screenshot.png|thumb|left|Bowser's Castle in ''New Super Mario Bros. Wii''.]]
[[Bowser]] is again fought in his castle in ''[[New Super Mario Bros. Wii]]''. After clearing {{world-link|8|airship|World 8-Airship (New Super Mario Bros. Wii)}} for the first time, the characters reunite with [[Princess Peach]] before [[Kamek]] takes her to Bowser's Castle, which was hidden behind a rock wall in the northern part of World 8. The wall then recedes, revealing the castle, and Bowser's evil laugh is heard as Kamek swoops down into the castle with Peach. The characters go through three parts: The first is a normal side-scrolling area with lava, [[Lava Bubble]]s and [[Fire Bar]]s. The second part is a vertical area with draining lava which auto-scrolls downwards, more Fire Bars and some [[Dry Bones]] trying to stop Mario. The third is Bowser's lair. In the final battle, Kamek casts a spell to make Bowser grow massive and he chases Mario and the rest of the characters through his castle.

Later after the final battle, when six of the Koopalings flip Bowser on his belly, the castle starts falling down on top of them.

}}
Bowser has two castles in ''[[Super Mario 3D Land]]'', both located in [[World 8 (Super Mario 3D Land)|World 8]]. The first castle is the World 8 Castle. Its appearance is similar to castles of the previous titles, as well as the previous castle levels in the game. At the end of the castle Mario fights Bowser and defeats him by pressing the switch at the end of the bridge, causing Bowser to sink in the lava below. Mario makes his way to Peach (which can previously be seen in the level using a pair of [[binoculars]]), only to discover that it is just a cardboard cutout. Bowser then appears with the real Peach in hand and flees to his larger castle, which is the true Bowser's Castle.

The real Bowser's Castle differs from previous castle levels, as Mario spends much of it riding [[Spine Coaster|Bone Roller Coaster]]s. Mario then reaches a cannon which launches him to a tower with another cannon on it, which Mario uses to reach Bowser's tower. No [[Checkpoint Flag]]s are found in this level, although there is an invisible checkpoint at the start of Bowser's fight. Mario then walks to the big red door and enters. Peach is tied up to the flagpole, but before Mario can rescue her, Bowser falls from above and attempts to crush Mario, which causes the floor to collapse and the final battle begins. Bowser attacks Mario with fireballs, spiked balls and barrels as Mario makes his way up the castle until they reach the second bridge. Mario tricks Bowser into clearing the path to the switch, which Mario presses, causing the bridge to collapse and Bowser to fall. However, as Mario continues to make his way up the castle, Bowser returns and pursues Mario, breathing purple flames which jet towards Mario, until they reach the final bridge, in which Bowser chases Mario until Mario reaches the final switch, which he presses, once again causing the bridge to explode, sending Bowser falling into the lava. Mario then rescues Peach and they head back home.

After completing the Special Worlds, Bowser kidnaps Peach again and Mario must return to his castle to defeat him and save Peach once again.

====''New Super Mario Bros. 2''====
{{Main|World 6-Bowser's Castle}}
[[File:NSMB2-Bowser Castle Course Icon.png|frame|left]]
Bowser's Castle reappears in [[World 6 (New Super Mario Bros. 2)|World 6]] of ''[[New Super Mario Bros. 2]]''. Like in ''New Super Mario Bros. Wii'', Mario and Luigi face Bowser twice at the end of the castle. Its appearance in this game is again similar to that of ''New Super Mario Bros.''
{{br}}

====''New Super Mario Bros. U''====
{{Main|Peach's Castle (world)}}
Although Bowser's Castle itself does not appear in ''[[New Super Mario Bros. U]]'', Bowser after capturing Peach's Castle in the beginning of the game starts renovating the castle to better resemble his own castle, ultimately succeeding by the time Mario fights Bowser Jr. for the final time at the end of [[Meringue Clouds|World 7]]. After he is defeated, the castle returns to its normal state.

====''Super Mario 3D World / Super Mario 3D World + Bowser's Fury''====
{{main|World Castle}} {{main|The Great Tower of Bowser Land}}
In ''[[Super Mario 3D World]]'', Bowser's Castle reappears as [[World Castle]], the seventh world of the game. The castle appears to be floating high above the Sprixie Kingdom, the game's setting. A second castle appears in [[World Bowser]], the game's final world, and is themed after an amusement park.

====''Super Mario Maker'' / ''Super Mario Maker for Nintendo 3DS''====
In ''[[Super Mario Maker]]'', Bowser's Castle appears in the 10 Mario Challenges and the 100 Mario Challenges.

====''Super Mario Odyssey''====
{{main|Bowser's Kingdom}}
In ''[[Super Mario Odyssey]]'', Bowser's Castle is located in [[Bowser's Kingdom]]. The castle featured in the game was constructed specifically for Bowser's wedding with Princess Peach.<ref>{{cite|title=''[[The Art of Super Mario Odyssey]]''|page=263}}</ref> Unlike in most games, in which the castle has a Western design, the castle featured in this game is traditional [[Japan|Japanese]] castle, with a concentric series of walls and baileys, a traditional garden and tea house, and a central keep. Instead of the usual [[lava]], its moats are filled with [[Poison (obstacle)|poison]].

====''Super Mario Maker 2''====
In ''[[Super Mario Maker 2]]'', Bowser's Castle appears as a background cameo in castle-themed ''[[Super Mario 3D World]]'' courses. In the version 3.0.0 update, it also appears as a world part for World Maker.

====''Super Mario Bros. Wonder''====
[[File:SMBW CastleBowser Render.png|thumb|Castle Bowser in ''Super Mario Bros. Wonder'']]
Although the location itself does not make an appearance, a variation is used for the game where Bowser merged with his Koopa Clown Car and Prince Florian's castle to become [[Castle Bowser]]<ref>{{media link|SMBW Trading Cards.png|''Super Mario Bros. Wonder'' trading cards}}</ref> via the [[Wonder Flower]]'s power. He uses this form to conquer portions of the [[Flower Kingdom]].

===''Super Mario Bros.: Peach-hime Kyūshutsu Dai Sakusen!''===
[[File:TheGreatMissionKingKoopasCastle.png|thumb|left|Bowser's castle as seen in ''Super Mario Bros.: Peach-hime Kyūshutsu Dai Sakusen!'']]
In the anime movie ''[[Super Mario Bros.: Peach-hime Kyūshutsu Dai Sakusen!]]'', Bowser turns [[Peach's Castle]] into his own after kidnapping [[Princess Peach]] and conquering the [[Mushroom Kingdom]]. While under his control, the building is situated on a tall mountain and is furnished to Bowser's liking, among other things featuring catacombs filled with traps to stop [[Mario]] and [[Luigi]]. The castle is destroyed after Luigi accidentally floods it while mining for [[coin]]s; once Bowser is defeated, his spell on the Mushroom Kingdom is broken, restoring Peach's Castle to its original form.

===DIC cartoons===
====''The Super Mario Bros. Super Show!''====
In ''[[The Super Mario Bros. Super Show!]]'', King Koopa owns a wide range of castles, ranging from fortresses, towers and even an ice palace; most often at the end of an episode, the featured castle of King Koopa would be destroyed and if not, would likely not be seen again. Unlike the games, the various castles seen in ''The Super Mario Bros. Super Show!'' lack the abundance of traps that would normally appear in a castle owned by Bowser.

====''The Adventures of Super Mario Bros. 3''====
[[File:BowsersCastleSMB3Toon.jpg|thumb|Kastle Koopa as seen in ''The Adventures of Super Mario Bros. 3''.]]
''[[The Adventures of Super Mario Bros. 3]]'' migrates away from the concept of King Koopa owning several castles and, instead, he only owns one castle, located in [[Dark Land]]. This castle is interchangeably referred to by the names "Kastle Koopa" and "Koopa Kastle". Kastle Koopa largely resembles its video game counterpart, with Bowser's image engraved on it, although it is blue in color and lacks the towers. Kastle Koopa also possesses a large hall filled with portraits, as well as bedrooms for the [[Koopalings]] and a laboratory most often used by [[Ludwig von Koopa|Kooky von Koopa]].

====''Super Mario World'' television series====
[[File:BowsersCastleSMWToon.jpg|thumb|left|The Neon Castle from the ''Super Mario World'' cartoon.]]
In the ''[[Super Mario World (television series)|Super Mario World]]'' cartoon produced by [[DIC Entertainment]] and Nintendo, the main base and home for Bowser and the Koopalings is called '''King Koopa's Neon Castle'''. Apparently located in a lava filled wasteland, Neon Castle lacks the amount of towers its game counterpart possesses, only having one; Neon Castle also possesses a rectangular shape and, like the Japanese version of the game, has "KOOPA" flashing in neon lights on its front, instead of "BOWSER". The castle carries over many of its game counterpart's traps, like [[Spinner|Ball 'N' Chain]]s, lava, [[Bowser Statue|fire-breathing statues]] and various kinds of minions. In the episode [[Mama Luigi]], Mario refers to it as King Koopa's "'''Coney Island Disco Palace'''", possibly based off of the final section of Bowser's Castle in that game, which featured a "[[ON/OFF Switch|disco ball]]" that illuminated it.
{{br}}

===''Super Mario Adventures''===
In ''[[Super Mario Adventures]]'', Bowser's Castle is only seen near the end of the comic and is portrayed as a large fortress, having many spike-covered towers and a large great hall, capable of holding several hundred different creatures. Catacombs and a lava filled chamber inhabited by [[Blargg]]s are also depicted in this version of Bowser's Castle.

===''Mario Kart'' series===
A new Bowser's Castle course has appeared in every ''[[Mario Kart (series)|Mario Kart]]'' game to date. It is one of three settings with this property, alongside [[Mario Circuit]] and [[Rainbow Road]]. Unlike them, this even extends to titles outside the main series. ''[[Super Mario Kart]]'' introduces three Bowser's Castles, while ''[[Mario Kart: Super Circuit]]'' introduces four. While ''[[Mario Kart Tour]]'' does not introduce a fully unique Bowser's Castle course, it does feature [[RMX Bowser's Castle 1]], a [[remix course]] based on ''Super Circuit''{{'}}s versions, particularly {{classic-link|GBA|Bowser's Castle 1}}.

Starting from ''Super Circuit'', Bowser's Castle courses are the third course of the [[Special Cup]]. They typically feature lava, [[Thwomp]]s, dangerous jumps, and [[Bowser Statue|giant statues of Bowser]] attacking the racers.

===''Mario is Missing!''===
[[File:Mario Captured.gif|thumb|Bowser's Castle in ''Mario is Missing!'']]
Bowser's Castle is the main setting of ''[[Mario is Missing!]]'', and it is unusually located in [[Antarctica]]. It contains many doors with portals to various cities around the [[real world]].

===''Mario's Time Machine''===
The castle is the main setting for the MS-DOS and SNES versions of ''[[Mario's Time Machine]]'', specifically as the location of [[Bowser's Museum]]. In the NES version, Bowser's Museum is instead a separate building.

===''Yoshi's Safari''===
{{main|Bowser's Castle (Yoshi's Safari)}}
Bowser's Castle is the last level in the final area in ''[[Yoshi's Safari]]'', which is the [[Dark Realm]] of [[Jewelry Land]]. After being defeated, Bowser retreats.

===''Yoshi's Island'' series===
====''Super Mario World 2: Yoshi's Island''====
{{main|King Bowser's Castle (Super Mario World 2: Yoshi's Island)}}
In ''[[Super Mario World 2: Yoshi's Island]]'' and its [[Yoshi's Island: Super Mario Advance 3|Game Boy Advance version]], Bowser's Castle is located atop a tall mountain in [[World 6 (Super Mario World 2: Yoshi's Island)|World 6]]. The last level takes place here and it requires the player to go into one of four random doors. Afterward, a giant playroom for [[Baby Bowser]] is discovered inside. After defeating Baby Bowser, Kamek will come by and make him extremely large. The player fights on the top of the castle which, throughout the battle, is slowly destroyed. The castle is later entirely destroyed after the final battle.

====''Yoshi's Island DS''====
{{main|At Last, Bowser's Castle!}}
[[File:Bowser's Castle (YIDS).png|thumb|Bowser's Castle in ''Yoshi's Island DS'']]
In ''[[Yoshi's Island DS]]'', Bowser travels back to the past searching for the seven Star Children so he could rule the universe. He takes over the castle of his younger self. After Baby Bowser is defeated, Bowser himself is faced. When he is defeated the first time, Kamek makes Bowser gigantic and destroys the castle in the battle.

====''Yoshi's New Island''====
{{main|Bowser's Castle Break-In|Make Way for King Bowser!}}
[[File:Baby Bowser's Castle Break-In.png|thumb|left|Yoshi inside Bowser's Castle in ''Yoshi's New Island'']]
In ''[[Yoshi's New Island]]'', Yoshi ventures to Bowser's Castle to save Baby Luigi and the Stork from the clutches of Bowser. Throughout the level, Yoshi must collect four [[key]]s to reach Baby Bowser. The final boss fight is very similar to that of the previous games; Yoshi must throw three eggs at him to proceed. In the second phase, however, Baby Bowser grows giant and attacks from the background, requiring Yoshi to throw [[Mega Eggdozer]]s at him. Once he takes three hits, Yoshi rescues Baby Luigi and the Stork, and the Mario Bros. are delivered to their house.

If the player has completed every level in the game without using [[Flutter Wings]] or [[Golden Flutter Wings]] (excluding special levels), Bowser will travel back in time to serve as the true final boss of the game. During the first phase of the battle, Bowser will attack by rearranging the ground and blowing fire at Yoshi. To defeat him, the player must hit him with [[Metal Eggdozer]]s three times. The second phase of the battle is nearly identical to the second phase of Baby Bowser's battle; however, this time Kamek will cast spells at Yoshi. Once the player throws three Mega Eggdozers at him, Bowser returns to his own time, and Yoshi saves Baby Luigi and the Stork once and for all.

{{SMRPG map}}
In ''[[Super Mario RPG: Legend of the Seven Stars]]'', the castle is localized "Bowser's Keep" and is isolated on a mountain of red, jagged rocks. The keep rests on the largest rock, which resembles Bowser himself. The castle can only be accessed by a long bridge that connects to the faraway [[Vista Hill]]. The halls of Bowser's Keep are lined with statues of [[hammer]]-holding [[Terrapin]]s, which are the soldiers that originally guard the castle (sans hammer). At the very beginning of the game during a standard princess rescue, Mario goes through an entry room, a heavily guarded hallway, and a lava-filled room with bridges (the second of which collapses, being later replaced with [[Donut Block|Donut Lift]]s), before battling Bowser atop a chandelier in a large room.

The rescue is interrupted by the gigantic sword [[Exor]] crashing into the keep, scattering everyone inside. Exor destroys the bridge and proclaims the keep the new base of the [[Smithy Gang]] in [[Mario World|Mario's world]]. Since Exor is the gateway to Smithy's dimension, the soldiers of the Smithy Gang have an easy time taking control of the castle. In fact, many of Bowser's soldiers defect or run away instead of fighting.

Eventually, Mario and his team make it back to the keep using the [[royal bus]] from [[Nimbus Land]]. After traveling through the original rooms, now full of stronger versions of early-game enemies, such as [[Terra Cotta]]s, [[Pro Goomba]]s, and [[Malakoopa]]s, intermixed with some larger enemies. After passing through the room where Mario and Bowser fought in the beginning, they travel through a dark, twisted hall and meet up with the thief [[Croco]], who offers to sell them items. Following this is a challenge of six doors known as [[the Trial Course]]. After four of the six are completed, they fall from a doorway into a tall room and get into a battle against the brainwashed [[Wizakoopa]]. After being defeated and freed from his mind control, Wizakoopa creates a [[magic treasure box]] and offers free healing, while a nearby Croco sells better items than before. The next room is a long hall filled with [[Thwomp]]s (including a [[Big Thwomp|large one]]), while [[Blazer]]s are shot from off-screen and lead to battle against [[Big Blaster]]s if touched. The final room is a copy of the Bowser fight room and is held by [[Boomer (Super Mario RPG)|Boomer]]. Once Boomer is defeated, the group is taken to the roof, where they battle Exor.

In the epilogue, Exor crumbles to dust, and the castle is shown being repaired by the reestablished Koopa Troop.

{{main|P. 6-Finale}}
[[File:Bowser's Castle (YS).png|thumb|left|Bowser's Castle in ''Yoshi's Story'']]
In ''[[Yoshi's Story]]'', Baby Bowser's Castle is split into four different areas: [[Mecha Castle]], [[Lift Castle]], [[Ghost Castle]], and [[Magma Castle]]. No matter what part of the castle Yoshi decides to go to, he will always meet up with Baby Bowser. The outside of the castle will also be seen whenever one of the Yoshis gets defeated, captured and brought to the castle, along with when [[White Shy Guy]] retrieves one. It is also seen in the ending sequence when Baby Bowser's minions carry him away.

Compared to most of the castle's other appearances, which at least look cartoonish in some way, this iteration of the castle looks much more ominous and menacing.

===''Mario Tennis'' series===
[[File:BowsercastleMTO.jpg|thumb|Bowser's Castle is a tennis court in ''Mario Tennis Open'']]
Bowser's Castle has made various appearances throughout the [[Mario Tennis (series)|''Mario Tennis'' series]], usually as the setting of various tennis courses. In  ''[[Mario Tennis (Nintendo 64)|Mario Tennis]]'' for [[Nintendo 64]], Bowser's Castle is the location of the [[Bowser Court]]. In ''[[Mario Power Tennis]]'', the [[Bowser Castle Court]] takes place here, and unlike the Bowser Stage in the previous game, it functions as a standard court. In ''[[Mario Tennis Open]]'', Bowser's Castle directly appears as a tennis court of the [[Bowser's Castle (Mario Tennis Open)|same name]]. In ''[[Mario Tennis Aces]]'', Bowser's Castle is located in the center of [[Inferno Island]], and it unusually has a temple-like structure; it is where the [[Battle the Treasure Guardian!]] mission takes place.

{{PM map}}
[[File:PM Bowserscastle.png|thumb|left|Bowser's Castle in the sky]]
In ''[[Paper Mario]]'', a new Bowser's Castle is secretly built right underneath [[Peach's Castle]] and Bowser lifts it into the sky, kidnapping Princess Peach, along with her castle. The power used to lift the whole castle into the sky is the [[Star Spirits]]' and the [[Star Rod (Paper Mario)|Star Rod's]] power, both of which Bowser had stolen from [[Star Haven]]. Bowser also jails the [[Chancellor|Toad Minister]] and nine other [[Toad (species)|Toad]]s, a [[Dryite]] and a [[Bumpty]] who failed to escape during [[Princess Peach]]'s party. There are two [[Toad House]]s (made from the slate in the prison), a shop run by a [[Spiked Goomba]], [[Storehouse]] and three [[Guard Door]]s. In the end, Mario manages to take back the Star Rod as well as save Princess Peach and her castle. Bowser's Castle, meanwhile, ended up destroyed alongside the nearby [[Power Platform]], the latter due to it undergoing a meltdown due to the intensity of Mario and Bowser's fight. In this game, Bowser's Castle looks bigger than Peach's.

Some notable residents of Bowser's Castle include [[Guard Door]], [[Mr. Hammer]], [[Spiky John]], [[Spiky Tom]], and [[Chancellor|Toad Minister]]. There is also a bored [[Spiked Goomba]] who sells items without Bowser's consent ([[Storehouse]]), and two [[Toad (species)|Toad]]s who make [[Toad House]]s with the slate in the prisons.

====''Paper Mario: The Thousand-Year Door''====
In ''[[Paper Mario: The Thousand-Year Door]]'', Bowser's Castle does not play a major role, as only the outside and a hallway are seen. Its appearance is mainly to show [[Kammy Koopa]] explaining to Bowser what happened to the Princess.

====''Super Paper Mario''====
In ''[[Super Paper Mario]]'', the castle has an equally minimal role, as it is where [[Count Bleck]] kidnaps Bowser's [[Koopa (species)|Koopa clan]] and [[Tippi]] takes Mario to [[Flipside]]. This is the exact same castle seen in ''Paper Mario: The Thousand-Year Door''. However, in [[The Bitlands]], Bowser found a set of several smaller castles, where several of his minions were located. After Mario destroyed them and defeated the Koopa King, the Princess convinced him to join them on their quest.

====''Paper Mario: Sticker Star''====
{{main|Bowser's Sky Castle}}
Like in the first ''Paper Mario'', Bowser's castle is the final area in ''[[Paper Mario: Sticker Star]]''. It is initially disguised as a cliffhead. However, after Mario collects all Royal Stickers, he manages to reveal via paperization the true form of the cliff. Bowser causes castle to float to prevent Mario from entering, although [[Wiggler #Paper Mario: Sticker Star|Flutter]] helps Mario arrive. Mario later defeats Kamek in this castle and later defeated Bowser (who is currently using the sixth Royal Sticker after he accidentally obtained it).

====''Paper Mario: Color Splash''====
{{main|Black Bowser's Castle}}
[[File:PMCS BlackBowsersCastle01.png|250px|thumb|Black Bowser's Castle]]
Bowser's Castle, called '''Black Bowser's Castle''' in-game, appears as the final area in ''[[Paper Mario: Color Splash]]''. It is on a floating island with an appearance similar to that of [[Bowser's Sky Castle]], but with warp pipes leading into the rock.

The castle's entry hall consists of a hallway where Princess Peach's portrait is initially seen, just out of reach. When Mario attempts to lower it, a trapdoor opens, leading to a confrontation with [[Roy Koopa]]. A door in the pit leads to a factory where all of the stolen paint from [[Prism Island]] is brought and mixed into [[black paint]], which is then used to color weapons such as [[Banzai Bill|Banzai Bills]] and [[Bob-omb|Bob-ombs]], which [[Black Bowser]] intends to use to paint the world black. Mario manages to destroy the tank holding the black paint, flooding the factory. The factory also has a warp pipe leading back to the entry hall.

Behind the wall where Peach's portrait was seen is a hallway leading to Bowser's throne room, with the princess now hanging above the throne. After Black Bowser is defeated, the castle begins to collapse from the black paint. Mario, Luigi, and Peach escape while [[Huey]] stays behind and, to ensure the black paint does not fall into the ocean, squeezes the castle, removing the black paint and transforming it into a card.

In battle, the Black Bowser's Castle card summons the castle and crashes it into opponents. It is also powerful enough to instantly defeat Black Bowser in battle.

[[File:PMTOK Bowsers Castle.jpg|thumb|left|Bowser's Castle, having crash-landed into the [[Shangri-Spa]] Banquet Hall]]
In ''[[Paper Mario: The Origami King]]'', Bowser's Castle boasts a similar design to that of the previous two games, although the design is about the same as [[Black Bowser's Castle]] from ''[[Paper Mario: Color Splash]]''. When Mario and [[Olivia]] first arrive at [[Shangri-Spa]] on their quest to destroy the green [[streamer]], they catch sight of a fortress with a scary-looking face in the distance that does not blend in with the area, also noticing that the streamer leads into the fortress. They soon meet [[Kamek]], who explains that the fortress is Bowser's Castle, where Bowser had retreated after escaping [[King Olly]]'s attack on [[Peach's Castle]] at the beginning of the game, but it was overrun with [[Folded Soldiers]] upon his arrival. Kamek had attempted to engage an emergency protocol for the castle, but pressed a button that shut down its engines instead, causing the castle to crash-land into Shangri-Spa's banquet hall. As a result, those who managed to avoid getting folded were forced to clean up the spa.

The entrance to the castle is initially guarded by an origami version of [[Boss Sumo Bro.]], who can only be reached with the help of [[Bowser Jr.]] After Mario defeats Boss Sumo Bro., the gang and a whole slew of uncorrupted minions (rallied by Kamek) barge into the castle and fight their way through the opposition. In the foyer, which also doubles as a mess hall, Mario can optionally fight the Folded Soldiers and earn 1,000 coins from each battle if the enemy was not instantly defeated with a [[First Strike]] in the overworld.

After finding that a door on the castle's second floor (where Bowser Jr. is trying to push himself through) is locked, Kamek guides Mario to his room for a key to the door, but mysteriously vanishes along the way, leaving Mario to find his way to Kamek's room himself. Inside a hallway lined with five doors, each leading to a room for a species of the Koopa Troop (from left to right: Goomba, Koopa Troopa, Kamek, Hammer Bro, and Spike) and with a Bowser portrait right above the door, Mario can peek through a small window to the left of each door for a hint of what he can find inside each room. There is a [[Flashy Mushroom]] behind some crates inside the room for Goombas, an Origami Koopa Troopa behind a [[treasure chest]] inside the room for Koopa Troopas, [[Luigi]] inside Kamek's room, an indicator for a [[Hidden Block|hidden]] [[? Block]] behind a toppled chair inside the room for Hammer Bros., and an Origami [[Spike]] inside another Treasure Chest plus a glimpse of a Collectible Treasure behind that chest inside a room for Spikes. The door to Kamek's room is initially camouflaged into a wall with a portrait of [[King Olly]] right above where the door would be; Mario must dislodge that portrait by hammering the wall right below the portrait repeatedly until it falls to the ground, revealing another portrait of Bowser. By doing so, a [[Magic Circle]] appears for Mario to use the [[1,000-Fold Arms]] to peel off the wall, revealing the door to Kamek's room. After Mario enters the room, Luigi hands him a [[Key to Bowser's Castle]]; Mario uses the key to unlock the door on the second floor that leads into another hallway, which is littered with sliced pieces of the Koopa Troop. Here, he is forced into a battle with [[Handaconda]], which has captured Olivia.

[[File:PMTOK Scissors.png|thumb|left|The Dual-Bladed Duelist: Scissors, boss of Bowser's Castle and guardian of the green streamer]]
After defeating Handaconda and freeing Olivia, Mario makes his way into the throne room, where he finds a spool for the green streamer, along with a recaptured [[Bowser]]. In that room, Mario runs into [[Scissors (boss)|Scissors]]; before engaging Mario directly, Scissors sends out [[Paper Mistake Buzzy Beetle]] as a warm-up for Mario. After Mario defeats Scissors in a near-death battle, a Magic Circle appears, allowing him to use the 1,000-Fold Arms to destroy the green streamer's spool. With the streamer cleared, the castle is officially back in Bowser's hands.

After being freed, Bowser directs Mario and Olivia to the castle's hangar on the first floor for a mode of transportation to Peach's Castle. First, in a room with nine Buzzy Beetle pillars arranged in a square, Mario must hammer a red button below a Bowser emblem on the west wall to activate a laser beam and hammer each pillar as necessary to create an S-shaped laser path through all nine pillars to another Bowser emblem on the north wall to unlock a door to the hangar. Inside the hangar, Mario must press a button on the left (next to the one that Kamek had pressed), which makes an [[airship]] emerge from a garage and dock itself at the hangar. Mario can read signs below the two buttons to reveal that their labels, one for "Secret Weapon" and the other for "Cut Engines" are wrong way round, for a very tiny writing on each sign states that the button's function is for the other one. After Bowser, Bowser Jr., Kamek, and the Koopa Troop board the airship, Mario must also get aboard and confirm to Bowser that he is ready to go for the airship to take off into the sky for Peach's Castle.

During the credits, a photo of Bowser Jr. and Bowser soaking in the [[Spring of Sanctuary]] shows Bowser's Castle undergoing repairs in the background.

===''Mario & Luigi'' series===
====''Mario & Luigi: Superstar Saga'' / ''Mario & Luigi: Superstar Saga + Bowser's Minions''====
[[File:MLSSBC.PNG|frame|left|The floating castle from ''Mario & Luigi: Superstar Saga'']]
[[File:MLSSDX BowserCastle.png|thumb|220px|Bowser's Castle in ''Mario & Luigi: Superstar Saga + Bowser's Minions'']]
In ''[[Mario & Luigi: Superstar Saga]]'' and its [[Nintendo 3DS|3DS]] remake ''[[Mario & Luigi: Superstar Saga + Bowser's Minions]]'', [[Bowletta]] goes back to the [[Mushroom Kingdom]] so she can use Bowser's Castle to attack the [[Beanbean Kingdom]] after being tricked into capturing [[Luigi]] disguised as [[Princess Peach]], which allows him to retrieve the stolen [[Beanstar]] from the repaired [[Koopa Cruiser]]. In this game, the castle is in the sky, can breathe fire, and resembles Bowser. Towers act as the castle's "hands", and around the castle's "torso" are cannons and an opening. This flying castle design is reused in ''[[Yoshi's Island DS]]''.

The castle acts as the final area of the game; Mario and Luigi fly there with [[Blablanadon]] near the end of the game to stop Bowletta after the latter hears about the castle attacking the Beanbean Kingdom and [[Prince Peasley]] being sent to stop it. The [[Beanbean Map|map]] of the game hides the castle throughout the majority of the game with a folded upper-left corner until it attacks [[Beanbean Castle Town]]; in the remake, the corner is not folded, and when Bowletta launches her attack, a picture of the castle is taped onto the map instead. Within the castle, the Mario Bros. must battle many of Bowser's troops and fight each of the [[Koopalings]] (some with [[Time Bob-omb]]s on their side) in their respective rooms in order to progress further, until they make it to [[Fawful]].

After defeating Fawful, the Mario Bros. make it into the throne room where Bowletta resides. Bowletta reveals she will not only conquer the Beanbean Kingdom, but the Mushroom Kingdom as well, and attacks the Mario Bros. They fight and seemingly defeat Bowletta after a long battle, but a Time Bob-omb suddenly appears and knocks them out, and she then swallows the brothers. Inside her body, the Bros. must fight and defeat [[Cackletta]][[Cackletta#Soul|'s spirit]]; after they defeat her, they are ejected out of Bowletta's body before she is turned back into Bowser and Cackletta's spirit perishes. The Mario Bros., Peasley and Blablanadon then escape the castle before it blows up, courtesy of a time bomb planted by Prince Peasley. Bowser regains consciousness and begins wondering what he has been doing the whole time, only for the castle to explode moments later and send him flying into the camera. The castle's remains crash into [[Oho Ocean]] in the original game, while it simply explodes and disappears in the remake; Bowser is fortunately saved by Prince Peasley.

The "main" grounded Bowser's Castle appears in the credits when the [[Toad Express]] drops the present containing Bowser through its roof. In the remake, only the exterior walls remain here, and the ''Minion Quest'' ending has the castle being rebuilt after Bowser is dropped.

In ''[[Mario & Luigi: Partners in Time]]'', the Mario Bros. visit [[Baby Bowser]]'s castle in the past, after the [[Koopa Cruiser]] crashes into the castle upon being shot down by the [[Shroob]]s. Though the quartet are initially split up, they eventually reunite there and start their adventure together. Baby Bowser himself is never seen inside the castle during the entire game, though the Mario Bros. discover a Cobalt Shard that he is keeping inside a [[Treasure chest|chest]]. There is also a [[time hole]] there which links to [[Peach's Castle#Mario & Luigi: Partners in Time|Peach's Castle]] in the present. Oddly, the castle on the map in the present looks the exact same as the one in the past and still depicts Baby Bowser.

}}
In ''[[Mario & Luigi: Bowser's Inside Story]]'' and ''[[Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey]]'', the castle, here labeled as "Bowser Castle", is taken over by [[Fawful]], with [[Midbus]] taking control of operations. After Bowser helps fire a [[Banzai Bill]] at his hijacked castle from [[Dimble Wood]], Midbus commands the castle to elevate, dodging the Banzai Bill, and then lands it on top of Bowser. Mario and Luigi must travel to Bowser's [[Rump Command]] and cause Bowser to [[Super Bowser|grow large enough]] to fight his castle.

In battle, the Castle's main attack is a flying ram, which Bowser must counter by punching. Its main tactic is opening its entrance doors and releasing Spinies, which prevent Bowser from punching. After the castle is defeated, Midbus retreats and the castle is returned to its original location. Later, as Bowser attempts to enter the castle, Midbus commands it to hover out of Bowser's reach. After wandering to the opposite side of the area, Midbus fires a giant cannonball at Bowser, who Mario and Luigi must help by building up energy in his arms. With their assistance, he throws it back at the castle, damaging it badly enough to force it to land. Bowser then gains access to the castle, where he discovers that Fawful has not only brainwashed his minions, but had also turned his training facility into a [[Fawful Theater|theater]]. In the meantime, Bowser decides to see the show Fawful puts on. After a few minutes, the doors to the theater open. Inside, a Goomba acting under the orders of Fawful tricked him into sitting in a VIP chair, which fires Bowser onto the stage and forces him into a fight against Midbus.

After Bowser beats Midbus, Bowser is forced to eat a "victory feast" that Boos feed him. This causes him to become so fat that he gets stuck in the floor. After a strange hand grabs Princess Peach, Bowser falls through the floor and lands on a treadmill, where he manages to lose the excess weight. He is then blasted out by exploding Bob-Ombs and sent into the [[Tunnel]].

Later in the game, Bowser must return here to look for the second Star Cure, which he had stolen before the events of the game. Fawful has blocked the path to his treasure stash, and Bowser must push a Fawful statue off the castle balcony to break the barrier. However, his brainwashed minions begin to push against the statue too, trying to save the statue and push Bowser off the balcony, forcing the Mario Bros. to assist him and provide extra leg strength once more. Bowser finally makes it to his [[Treasure Chamber|treasure vault]] with the assistance of some Monty Moles, only for them to betray him and reveal that they turning the tunnel into a railway for the [[Fawful Express]].

[[File:M&LBIS Bowser's Castle Artwork.png|thumb|200px|left|Artwork shown before fighting the Gauntlet version in ''Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey'']]
After battling the Fawful Express, Bowser return to the Treasure Chamber to obtain the Star Cure from the safe. After recalling the combination with Mario, Luigi and [[Starlow]]'s help, Bowser opens the safe and grabs the Star Cure. However, his minions [[Private Goomp]], [[Corporal Paraplonk]] and [[Sergeant Guy]] then push him into the safe and trap him in it, announcing their betrayal and defection to Fawful. The safe is then moved eventually to [[Peach's Castle]].

Curiously, the castle has a cold-storage vault, in which a large part of the [[Shroob]] invasion force from the events of ''Partners in Time'' is kept frozen, along with [[Elder Princess Shroob|their]] [[Princess Shroob|princesses]], who somehow survived their defeat. If Mario and Luigi find the password required to enter this room, they can fight three of the Shroobs (which they inadvertently defrost) as optional bosses. According to ''Bowser Jr.'s Journey'', the cold-storage vault was originally created by Kamek to store the Ever Ice as a means to preserve it, despite its permanent nature, in the event that Bowser Jr. needed it - which he ultimately did thanks to the [[Blorbs]] outbreak at Bowser's kingdom.

During the credits, Bowser's minions are repairing the damages done to the castle. After being beaten by Mario and Luigi back at Peach's Castle, Bowser is carried back to his castle, and a Magikoopa treats him while he is bedridden. Birdley and Starlow arrive at the castle to deliver a present for him; a [[cake]] from Princess Peach. Before Bowser opens it, Starlow chats with him for a bit, and re-accepts Private Goomp, Corporal Paraplonk and Sergeant Guy back into his troop once they apologize for their betrayal, telling them to work on the repairs of his castle.

In the remake, the castle is labeled as "Bowser's Castle" and in the main game plays the same role as the original. There are no major changes in the rematch in the remake's [[Challenge Node]], other than the fact that the [[Shy Guy]]-manned [[airship]]s move faster and fire faster cannonballs more rapidly. In the ''Bowser Jr.'s Journey'' mode, it is revealed that after Fawful took over Peach's Castle, his treasonous minions the [[Best Fitness Friends]] took control of Bowser's Castle for themselves. In this mode, the castle's basement is labeled as the '''Lava Lair''', which Bowser Jr., Kamek and Morton explore after the Castle had taken off for Dimble Wood. Additionally, Bowser's Castle is the final area for ''Bowser Jr.'s Journey''. In the post game, due to Bowser challenging Bowser Jr. to a personal battle and neither one admitting defeat, the castle's repairs ended up undone.

====''Mario & Luigi: Dream Team''====
{{main|Neo Bowser Castle}}
While Bowser's Castle itself does not appear in ''[[Mario & Luigi: Dream Team]]'', [[Neo Bowser Castle|a new castle]] conjured from the [[Dream Stone]] is created during the events of the game, and serves as the stronghold for Bowser and [[Antasma]] on [[Pi'illo Island]]. At the end of the game, this castle is destroyed due to its source, the Dream Stone, being shattered as well as its rulers, Antasma and Bowser, being defeated.

====''Mario & Luigi: Paper Jam''====
{{see also|Neo Bowser Castle}}
[[File:MLPJ BowserCastle.png|thumb|Bowser's Castle as seen in a cutscene in ''Mario & Luigi: Paper Jam'']]
In ''Mario & Luigi: Paper Jam'', Bowser's Castle appears as an area located near [[Doop Doop Dunes]]. The castle can also be seen off in the distance at several points in the game. The castle also has a cannon built into the roof, which Bowser uses to destroy the bridge connecting his castle to Doop Doop Dunes as well as knock out Mario, Luigi and Paper Mario.

The castle is first seen during the first cutscene involving Bowser, where after a disagreement and then a brawl, he and his paper counterpart decide to team up. They proceed to kidnap their respective [[Princess Peach]]es and return to the castle. The castle is later seen in Doop Doop Dunes, where upon entering the area, the Mario Bros. and [[Paper Mario (character)|Paper Mario]] spot Bowser's Castle in the distance, which they must cross the desert to reach. As they come close, the Bowsers notice and decide to blast the gang with [[cannonball]]s. The first shot misses them, but destroys the bridge connecting the castle to the desert, while the second shot knocks them all out cold. [[Wendy O. Koopa|Wendy]], [[Roy Koopa|Roy]], [[Larry Koopa|Larry]] and [[Ludwig von Koopa|Ludwig]] then arrive to take them to the [[Twinsy Tropics Dungeon]], while the [[Bowser Jr.]] duo collects the book containing Paper Mario's world.

Much later in the game, the group reaches Bowser's Castle in order to rescue the princesses and get the book back. They learn the [[Trio Glider]] before encountering the two [[Kamek]]s and [[Papercraft King Boo]], who is controlled by [[Morton Koopa Jr.|Morton]] and [[Lemmy Koopa|Lemmy]]. [[Toadette]] also arrives just in time with a [[Papercraft Yoshi]] to fight the Papercraft King Boo. After the victory, Kamek kidnaps Toadette to bring the production of papercrafts to a stop, then prepares to build [[Papercraft Bowser]]. The gang later rescues Toadette before encountering the Bowser Juniors on guard duty.

The Princess Peaches then escape and greet the team, but are caught by the Bowser Juniors. They mean to fight, but after accidentally revealing they possessed the book the Bros. are after (which they did not know they had), the pair flee. The group eventually catches them and forces them to hand over the book, but the Juniors escape after giving them a decoy book. The gang chases them down and engages in a battle with them, defeating the pair. Before they can get the book back, the two Bowsers enter the room, enraged at their sons' defeat. They then activate "the boosters", lifting Bowser's Castle out of the lava moat and dubbing it "[[Neo Bowser Castle]]". The gang escapes, forgetting the book, and the Bowsers retaliate for their sons' defeat by firing on [[Peach's Castle]] and ravaging it. The castle is presumably returned to ground level after the Bowsers' defeat.

Unlike other ''Mario & Luigi'' games, the castle's design is based on its designs from ''New Super Mario Bros. Wii'' and ''New Super Mario Bros. 2'' and lacks the Bowser head and "arm towers" of the previous designs. Additionally, Bowser's Castle is located at the edge of a desert instead of a volcanic wasteland, although a giant lava moat is built around the castle. Additionally, this design does not have a stone head of Bowser anywhere, but instead has a green Bowser-like emblem logo in the center. Further reflecting on the designs of contemporary main series incarnations, the castle sports a large number of spiked green domes that resemble Bowser's shell.

After Bowser's Castle becomes Neo Bowser Castle, its original location at the end of Doop Doop Dunes [[Unrevisitable area|can no longer be explored]], even when the game is completed.

===''Mario Party'' series===
Bowser's Castle makes infrequent appearances in the ''Mario Party'' series. The minigame [[Bowser's Lovely Lift]] in ''[[Mario Party 7]]'' takes place in the castle, although only the tower holding the lift is seen. Several cutscenes in the story mode of ''[[Mario Party DS]]'' take place in Bowser's Castle. It is where [[Bowser's Pinball Machine]] is located and the final boss minigame, [[Bowser's Block Party]], takes place in the throne room of the castle. [[Chaos Castle]] from ''Mario Party 10'' takes place within the castle: The first part of the board takes place on the exterior, the second part takes place inside the castle with a factory theme before ending in the throne room. The [[Bowser Board]] in amiibo Party is also based on the castle. [[World 4 (Mario Party: Star Rush)|World 4]] of ''[[Mario Party Star Rush]]'' is based on Bowser's Castle.

===''Super Smash Bros.'' series===
Bowser's Castle sometimes appears in the [[Super Smash Bros. (series)|''Super Smash Bros.'' series]]. In ''[[Super Smash Bros. for Nintendo 3DS]]'' and later also ''[[Super Smash Bros. Ultimate]]'', a stage based on [[Bowser's Sky Castle]] from ''Paper Mario: Sticker Star'' appears in the [[Paper Mario (stage)|Paper Mario]] stage, where at certain intervals, the castle's eyes may light up and the castle entrance (modeled after Bowser's head) may turn or close its mouth, heavily damaging any character inside. Additionally, in ''Super Smash Bros. Ultimate'', the [[smashwiki:Molten Fortress|Molten Fortress]] sub-area in [[smashwiki:Adventure Mode: World of Light|World of Light]] is modeled after Bowser's Castle.

===''Mario Pinball Land''===
{{main|Fiery Stage}}
[[File:MPL Bowser's Castle.png|thumb|Bowser's Castle in ''Mario Pinball Land'']]
In ''[[Mario Pinball Land]]'', Bowser's Castle appears as the final area, being called the '''Fiery Stage''' by the manual. It is only accessible after Mario has defeated all the other bosses and collected at least 15 stars. The bosses can all be found and battled in the castle once more. Bowser must also be battled and defeated here in order to beat the game.

===''Super Princess Peach''===
{{main|Bowser's Villa}}
As ''[[Super Princess Peach]]'' takes place on [[Vibe Island]], rather than the Mushroom Kingdom, the castle itself is not seen during the events of the game. However, Bowser built [[Bowser's Villa|a villa]] there, which is considered to be another castle.

===''Mario Hoops 3-on-3''===
{{main|Bowser's Castle (Mario Hoops 3-on-3)}}
Bowser's Castle appears as a basketball court in ''[[Mario Hoops 3-on-3]]''. The court has many gimmicks, including [[Thwomp]]s, [[Lava Bubble]]s, and [[Bomb (species)|Bomb]]s.

[[File:ISWii18.png|thumb|200px|Bowser's Castle in ''Fortune Street'']]
Bowser's Castle also appears as a game board both in ''[[Itadaki Street DS]]'' and ''[[Fortune Street]]'', based on the castle settings from ''New Super Mario Bros.'' and ''New Super Mario Bros Wii'', respectively.

===''Mario & Sonic'' series===
Bowser's Castle has made various appearances in the [[Mario & Sonic (series)|''Mario & Sonic'' series]]. In the [[Wii]] version of ''[[Mario & Sonic at the Olympic Winter Games (Wii)|Mario & Sonic at the Olympic Winter Games]]'', Bowser's Castle is where [[Dream Ice Hockey]] takes place, and a background based on it is in the second segment of the Mario World routine in [[Dream Figure Skating]]. In the [[Mario & Sonic at the Olympic Winter Games (Nintendo DS)|Nintendo DS version]], [[Blizland]] has elements of Bowser's Castle, combined with elements of Dr. Eggman's factories. In ''[[Mario & Sonic at the Sochi 2014 Olympic Winter Games]]'', a large portion of [[Mario's Figure Skating Spectacular]] features a layout inspired by Bowser's Castle based on its appearance in ''Super Mario 3D Land''. In the Nintendo 3DS version of ''[[Mario & Sonic at the Rio 2016 Olympic Games (Nintendo 3DS)|Mario & Sonic at the Rio 2016 Olympic Games]]'', Bowser's Castle appears only on the overworld in the [[Mario & Sonic at the Rio 2016 Olympic Games (Nintendo 3DS)#Road to Rio|Road to Rio]] mode.

[[File:KingBowserCastle YWW.png|thumb|Yoshi in Bowser's Castle in ''Yoshi's Woolly World'']]
In ''[[Yoshi's Woolly World]]'' and ''[[Poochy & Yoshi's Woolly World]]'', Yoshi chases after Kamek to Bowser's Castle to save his fellow Yoshis. Once he enters the castle, he must seek [[yarn ball]]s of four different colors to open the door to Baby Bowser. The first phase of the boss fight is very similar to that of previous games. Yoshi must throw a yarn ball at Baby Bowser, stomp him, and repeat the process two more times to proceed. In the second phase, Baby Bowser grows giant and becomes Mega Baby Bowser. He jumps into the background and hurls big yarn balls at Yoshi. To win, Yoshi must throw these big yarn balls back at Mega Baby Bowser. Upon victory, the player unlocks eight new Yoshi colors, as well as [[List of Yoshi designs in Yoshi's Woolly World|Baby Bowser Yoshi]] if all five [[Wonder Wool]] in the level were collected.

===''Yoshi's Crafted World''===
{{main|The Great King Bowser (level)}}
In ''[[Yoshi's Crafted World]]'', Bowser's Castle reappears in the boss stage [[The Great King Bowser (level)|The Great King Bowser]]. Here, the Yoshis must defeat Baby Bowser. In his first phase, the Yoshis should defeat Baby Bowser's [[The Great King Bowser|robot]]. During the second phase, the Yoshis need to defeat Mega Baby Bowser. This level has to be completed to not only beat the game, but also unlock [[Hidden Hills]].

===Monopoly Gamer===
Bowser's Castle is the sixteenth and final property on the game board in [[Monopoly Gamer]]. It is one of two properties in the Dark Blue Color Set (along with [[Peach's Castle]]).

===''The Super Mario Bros. Movie''===
[[File:Bowser's ship tsmbm.jpg|thumb|left|Bowser's Castle in the [[Snow Kingdom (The Super Mario Bros. Movie)|Snow Kingdom]] in ''The Super Mario Bros. Movie'']]
In ''[[The Super Mario Bros. Movie]]'', Bowser's Castle is located on a giant floating [[airship]] (referred to as '''Bowser's ship''' by [[Cranky Kong]], '''Bowser's airship''' in the bonus features,<ref>"Leveling Up: Making ''The Super Mario Bros. Movie''" bonus feature subtitles</ref> and '''Bowser's Island Castle''' in a [[Jakks Pacific]] playset<ref>{{media link|TSMBM Bowser Island Castle Toy.jpg}}</ref>) that [[Bowser]] and [[Bowser's Minions|his forces]] use to travel between kingdoms. The ship consists of a volcano and [[lava]] similar to those seen in the [[Dark Land]]s, as well as a massive figurehead depicting Bowser's head and a giant pool of lava, resembling depictions of Bowser's Castle from ''[[Paper Mario]]'' and ''[[Mario & Luigi: Superstar Saga]]'', respectively, complete with [[Spike Ball]]s attached to [[Ball and chain (windup)|chains]] like the former acting as [[anchor]]s to help it descend. Additionally, the volcano's crater, as seen during Peach and Bowser's wedding held at the castle, is later revealed to also double as a missile silo used to launch the Bomber Bill that Bowser plans to use to destroy the Mushroom Kingdom once the wedding gets thwarted by the heroes.

After Bowser obtains the [[Super Star]] from the [[penguin]] army, he holds a celebration in his castle with his minions. Later in the film, [[Luigi]] is captured by the [[Shy Guy]]s and [[Snifit]] and transported to Bowser's Castle, where he is imprisoned along with the penguin army. The [[Kong army]] is also later captured and imprisoned at the castle after being ambushed by Bowser's minions. After getting sucked into [[Brooklyn]] through the [[mysterious pipe]], the ship and castle are destroyed by [[Mario]] and Luigi with the use of the Super Star.

====Area tattles====
*''It's Bowser's Castle. This appears to be the hangar for Bowser's [[Koopa Clown Car|vehicles]].
*''Boy! Bowser's Castle. Talk about your basic eerie atmosphere, huh? Oh... I'm nervous and excited at the same time. We're headed for the [[Bowser|final fight]] at last!
*''Are we still outside the castle or what? Let's hurry through here. OK, [[Mario]]?
*''I've gotta hand it to him, Bowser's Castle is amazing! Such creative use of lava flows! It's just like that [[Mt. Lavalava|volcano]]!
*''It's a covered hallway in Bowser's Castle. It doesn't look like anything's amiss in here. Let's press on, Mario.
*''Look at the size of that stone Bowser face! He's pretty scary looking. That face gives me the creeps, Mario.
*''It's an underground prison cell, Mario. Are you sure you can find the way back to where we were before?
*''I wonder where all this lava comes from. Don't you think it's odd?
*''Lava, lava, lava! There's such a thing as too much lava, that's for sure. Mario, are you all right in this heat? Boy, it's hot! This adventure has just been one extreme or the other.
*''The only way to cross the lava is to have somebody carry us. If we could find a way to cool the lava off, we could probably walk on it, though. And if we have to pass through lava flows, we can have Bow hide us from danger.
*''Here's the source of the lava. It's miserably hot when it's flowing. It's not so bad when it's cooled off, though.
*''Now we're cooking! I mean, now we're not cooking! It's still hot, but not, you know, burning hot.
*''You know, walking on newly hardened lava is not exactly something that your average Goomba gets to experience.
*''The lava seems to have hardened as it cooled off.
*''There's a treasure chest. Things are looking up. The lava has even cooled.
*''It seems to be a cave. Are we below the castle? It's so dark. They must have had problems setting up lights down here. What a pain for us.
*''It seems to be a cave. Are we below the castle? It's so dark. How long can this darkness possibly last?
*''Ah! We're back inside Bowser's Castle. There's a stone pedestal with Bowser's face carved on it. What poor taste! What an egomaniac! If we push that thing, what do you think will happen?
*''It's a hall in Bowser's Castle. I wonder where it leads. We have to hurry! And yet, we should also be careful.
*''These stairs aren't lighted very well, are they? I wonder how deep below ground they go. Bowser should really look into some ambient lighting.
*''This is a prison cell where Toads are being held. You know... There are Toads here...and beds... It's kind of like a Toad House! Do you think that I'm just an incurable optimist? Well, what's wrong with that?
*''Here's the storage room for Bowser's Castle. It looks like one of his subjects is selling his stuff. Ha ha!
*''It's a covered hallway. I can sum up the decorating in two words: pure Bowser! Such dark colors and drab lighting! What terrible taste!
*''I'm sure Bowser's going to be surprised. I'm sure he'd never believe that we could make it this far. I can't wait to see the expression on his face.
*''If Bombette were about three times bigger, we could just blow all these walls up. It would certainly let us move through these areas a lot faster. But that's probably not a good idea. It would be far too dangerous.
*''We're somewhere inside Bowser's Castle. This hall is quite large. It also looks quite fortified. I wonder if there's anything good around here? An attack item, maybe?
*''Look at all these carvings of Bowser's ugly mug. It's really shameless! I guess he thinks he's cool. Hey, incidentally, about those stone pedestals... Some move and some don't, so check 'em all out.
*''Whoa! This corridor has much lower ceilings, huh? I guess I had gotten used to really high ceilings.
*''In case you don't know by now, some of these Bowser pedestals can be pushed and others can't. In many cases, you can push them from either the right or left side. I wonder where I heard that?
*''This is a hidden passage. It's a bit dark, huh? That's all right. I can sense that something good's in here.
*''Some of these Bowser pedestals can be pushed and others can't. In many cases, you can push them from either the right or left sides. If they move, you can be sure they're covering a hidden passage.
*''See! A hidden passage. This one doesn't seem to be hiding anything interesting.
*''...Nothing. This room's just a dead end. How worthless. Let's go back to the room where the pedestals are and check 'em out!
*''This hidden passage looks promising, doesn't it? It must lead somewhere... You know, I hope we're going in the right direction. I feel kind of disoriented.
*''We've certainly seen many kinds of treasure on our adventures, haven't we, Mario? There's one that I would value above all others, though. I would keep it in the safest place I know... Mario, please give me your autograph!!
*''Again with the Bowser faces! I'm sick of looking at his ugly mug! Let's find the real Bowser and show him who's boss! And then I can meet Princess Peach!
*''It's the outside of Bowser's Castle. Even the outside feels gross and ominous. Maybe he wasn't so bad until he moved here. Living in such a dank place isn't good for the soul.
*''How many halls have we been through? I wonder what this one leads to... To Bowser's room? Maybe?
*''Know what this reminds me of? A ghost story! This would make the perfect setting for a freaky ghost story! We could have Bow and her friends play the scary parts. Remind me to do that some time back at Toad Town!
*''It's a prison cell within Bowser's Castle. A lot of Toads are here. It's a bit strange... Why would Bowser ever need this many prison cells? Do you think there are that many prisoners?
*''I think we've already come really far. But we're not at Bowser's room yet. Where could he be? This place is so complicated! That Bowser... I really don't like him!
*''"I smell treasure!" Isn't that a good Kolorado imitation? Mario? Wasn't that right on? I wonder what Kolorado's doing?
*''It's a covered hallway in Bowser's Castle. There's no place to hide around here, that's for sure. Not that we need one, Mario! Who'd hide? Not me!
*''Do you think those windows open to outside or to the inner part of the castle? I'm getting totally turned around in here. This castle really is huge.
*''It's a room without a window. It also has a chandelier with no lights in it. I'm getting the feeling that Bowser is really going for the dark, gothic look in here. Maybe he hates bright lights.
*''All the torches hanging over there... Doesn't their pattern strike you as sort of suspicious? It's almost as if there's a hidden meaning there. What do you say we try to remember it?
*''I think we keep passing through the same room. Do you think, perhaps, that somebody's messing with us? Well, it's a waste of time to just keep running around with no clue about what we're doing. It's kind of like what happened in Forever Forest. Say...those torches might hold a clue for us.
*''This is a corridor of sorts. I guess it's more like an elevated skyway, though. If a guy were afraid of heights, his legs would probably tremble and he'd probably freak out. Gulp!
*''You know, if I were designing a castle, I wouldn't put in so many corridors. Well, whatever. You can't expect Bowser to have good taste.
*''This room is one big ego massage for Bowser. I wish we could crush all these statues to dust.
*''Stairs again! Do you think Princess Peach's Castle is at the top of 'em? We're almost there, Mario! I can feel it! Onward! The princess awaits!

====Map descriptions====
*''It's the castle of the wicked King Bowser, of course. To kidnap Princess Peach, he stole the whole castle. Now Princess Peach's Castle teeters atop Bowser's Castle.''
*''Bowser's Castle used to be right here! That evil Koopa stole Princess Peach's Castle and captured Princess Peach.''

==Trivia==
*In both ''[[Nintendo Comics System]]'' and ''[[Nintendo Adventure Books]]'', Bowser's Castle was infrequently seen and was shown to have a labyrinth like construction, possessing various passages, bridges and doorways.
*In ''[[Mario Golf: Toadstool Tour]]'', a course known as the [[Bowser Badlands]] is located near Bowser's Castle.
*According to an article on [http://www.movoto.com/ Movoto.com], a real-life version of Bowser's Castle based on its appearance in ''[[Super Mario Bros. 3]]'' would be 212 stories high, 52 stories taller than the tallest building in the world, the {{wp|Burj Khalifa}}. However, due to the assumption that the castle should be merely 60 inches wide, it would cost only $455,000.<ref>{{cite|url=www.movoto.com/blog/infographic/real-life-bowsers-castle-jump-on-this-deal-before-mario-does|title=Movoto: Real-Life Bowser’s Castle: Jump on this Deal Before Mario Does|accessdate=February 9, 2015}}</ref>
*In ''[[Paper Mario: The Thousand-Year Door]]'', Bowser can find an unseen item by checking one of the Bowser statues. A similar occurrence also happens with the bushes in Twilight Town.
