Bowser's Castle

"Oh dear! Why are we playing in Bowser's Castle? There are all sorts of tricks and traps in here!"

- Princess Peach

Bowser's Castle is a recurring location in the Mario series. It is the domicile of the Koopa villain Bowser and the base of operations for his army. The castle's name, design and greater location vary from game to game, but the castle is usually situated in a volcanic world 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 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.

Super Mario Bros. / Super Mario Bros.: The Lost Levels
Bowser's Castle first appears in Super Mario Bros. at the end of World 8. In the level 8-3, Mario battles Bowser's forces outside of the castle, which can be seen in the background; in World 8-4, Mario ventures into the castle itself, where he battles and defeats Bowser in order to save Princess Peach. It is similar in Super Mario Bros.: The Lost Levels, except that it appears in world D-3 and D-4 instead, while a castle located in the sky is found in World 8-4. In Super Mario All-Stars, Bowser's Castle is easily distinguished from the other castles by having thunder and lightning flash in the background.

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. The mentioned castle is one of the longest levels in the game. Bowser is fought at the end of the castle and Princess Peach is freed. The map icon was modified in Super Mario Advance 4: Super Mario Bros. 3 so that it is animated.

Super Mario World


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 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.

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 Thwomps, Dry Bones, Rocket Engines, as well as Podoboos. 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 Rocket Engines) 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
 Bowser is again fought in his castle in New Super Mario Bros. Wii. After clearing the final airship level 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, 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, Podoboos and Fire Bars. 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, Bowser and the six Koopalings are flattened by the castle as it falls over.

Super Mario 3D Land


Bowser has two castles in Super Mario 3D Land, both located in World 8. The first castle is the World 8 Castle, its appearance is similar to castles of previous titles, as well as 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 it's 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 Bonecoasters. Mario then reaches a cannon which launches him to a tower with another cannon on it, which Mario uses to reach Bowser's tower. Mario then walks to the big red door and enters. Peach is tied 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
Bowser's Castle reappears in 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.

Super Mario 3D World
Bowser's Castle reappears in World Castle, the seventh world of the game (In fact, the whole world takes place in the castle).

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
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 referred by the name "Castle Koopa" and "Koopa Castle". Castle Koopa largely resembles its game counterpart, with Bowser's image engraved on it, though it's blue in color and lacks towers. Castle Koopa also possesses a large hall filled with portraits, as well as bedrooms for the Koopalings and a laboratory most often used by Kooky von Koopa.

Super Mario World television series
In the Super Mario World cartoon produced by DIC Entertainment and Nintendo, the main base and home for Bowser and the Koopalings is called "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 Spinners, lava, fire-breathing statues and various kinds of minions. In the episode Mama Luigi, Mario refers to it as Bowser's "Coney Island Disco Palace", a name most likely based off of the final section of Bowser's Castle in that game, which featured a disco ball that illuminated it.

Mario is Missing!
Bowser's Castle is the main setting of the game Mario is Missing!, but instead of being located in the Koopa Kingdom, like in the other games, this castle is located in Antarctica. The castle is also the main setting for the game Mario's Time Machine, except this time it's located in an unknown area.

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 Blarggs are also depicted in this version of Bowser's Castle.

Mario Kart series
Bowser's Castle has appeared in every Mario Kart game to date. In Super Mario Kart, there is a different course of the castle in every Cup except the Special Cup. Bowser Castle 1 appears in the Mushroom Cup, Bowser Castle 2 appears in the Flower Cup and Bowser Castle 3 in the Star Cup. Mario Kart: Super Circuit features all of the courses from Super Mario Kart, so they appear in that game as well. Also the Paper Mario castle makes a cameo appearance in the Rainbow Road track. Mario Kart 64 features a Bowser's Castle course in the Star Cup. In 50cc mode, there is one Thwomp, in 100cc mode, there are two and in 150cc and Extra modes, there are three Thwomps right before turn 4. Mario Kart: Super Circuit has its own Bowser's Castle courses, but it also has a fourth one. Mario Kart: Double Dash!! and the later games of the series have a Bowser Castle course in the Special Cup. It also features Bowser Castle 2 from Mario Kart: Super Circuit (Banana Cup section) in Mario Kart DS, the same Bowser Castle from Mario Kart 64 (Lightning Cup) and Bowser Castle 3 from Mario Kart: Super Circuit (Leaf Cup section) in Mario Kart Wii and Bowser Castle 1 from Mario Kart: Super Circuit (Shell Cup section) in Mario Kart 7 as the retro courses. Every version of the course features the same dangers: lava, Thwomps (with the exception of Mario Kart 8) and dangerous jumps. In Mario Kart 8, the track features an anti-gravity section which goes around a giant lava Bowser, who occasionally slams a fist onto one of the tracks, blocking racers. It is also the first course to not feature Thwomps.

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.

Super Mario World 2: Yoshi's Island
In Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3, Bowser's Castle is located atop a tall mountain on the island. 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 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.

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.

Super Mario RPG: Legend of the Seven Stars


During the events of Super Mario RPG: Legend of the Seven Stars, the castle is named "Bowser's Keep" and is isolated on a mountain of red, jagged rocks. The keep rests on the largest rock, which, in fact, 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 Brothers and Bowser. The castle is originally guarded by Terrapin soldiers. Additionally, molten lava flows through the keep in several areas. Fortunately, several bridges allow access across the lava. Unfortunately, the bridges are wooden and as such, will eventually collapse in a room filled with lava. In fact, one bridge breaks right after Mario walks across it. Later, this bridge is replaced with hovering Donut Blocks. The castle is also filled with ornate chandeliers. Mario and Bowser actually duel on the top of these chandeliers.

Bowser's Keep is also the Smithy Gang's base of operations in Mario's World. During the beginning of Smithy's invasion, the gigantic sword Exor crashes into the keep. 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, the Smithy Gang claims the castle as their own. Additionally, Exor destroys the bridge connecting Bowser's Keep to the outside world. As such, the castle can only be accessed by flying vehicles.

Before the fight against Magikoopa, there will be 6 doors to choose from, though only four doors are required. There are two action courses, two battle courses and two puzzle courses.

Paper Mario
In Paper Mario, a new Bowser's Castle is secretly built right underneath Princess 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's power, both of which Bowser had stolen from Star Haven. Bowser also jails Toadsworth and other nine Toads, a Dryite and a Bumpty who failed to escape during Princess Peach's party. There are two Toad Houses (made from the slate in the prison), a shop run by a Spiked Goomba, Storehouse and three Guard Doors. 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.

Notable residents
There is also a bored Spiked Goomba who sells items without Bowser's consent (Storehouse), and two Toads who make Toad Houses with the slate in the prisons,

Paper Mario: The Thousand-Year Door
In Paper Mario: The Thousand-Year Door, Bowser's Castle doesn't 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 the entire 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
Like in the first Paper Mario, Bowser's castle is the final area in Paper Mario: Sticker Star. It was initially disguised as a cliffhead. However, after Mario collected all of the Royal Stickers, he managed to reveal via paperization the true form of the cliff. Nonetheless, Bowser had his castle levitated to the sky as a means to deter Mario's advance on it shortly thereafter, although he nonetheless managed to arrive there via a Flutter that Mario befriended. Mario later fought and vanquished Kamek in this castle and later defeated Bowser (who was currently using the sixth Royal Sticker after he accidentially obtained it).

Paper Mario: Color Splash
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 pipes leading into the rock.

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

Behind the wall where Peach's portrait was is a hallway leading to Bowser's throne room, with the princess now hanging above the throne. After Bowser is defeated, the castle begins to collapse, due to 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 the opponents.

Mario & Luigi: Superstar Saga
In Mario & Luigi: Superstar Saga, Bowletta uses Bowser's Castle to attack the Beanbean Kingdom. This castle can fly, breathe fire and it looks like a statue of Bowser. On the castle's "hands" there are tower tops. Mario, Luigi and Prince Peasley go there with Blablanadon near the end of the game to stop Bowletta. The castle is the final world of the game. In the castle, the Mario Bros. have to get through many challenges and fight each of the Koopalings (some with Time Bob-ombs) in their room in order to open the next area until they make it to Fawful. After the fight, the Mario Bros. get to the throne room where Bowletta resided. They fought Bowletta, but she then swallows the Bros., making them fight Cackletta's spirit inside Bowletta's stomach. After the Mario Bros., Peasley and Blablanadon escape the castle, a time bomb planted by Prince Peasley blows the castle up and the remains crash into the Oho Ocean. This flying castle design is reused in Yoshi's Island DS and is somewhat similar to the one featured in Paper Mario.

The ground version of Bowser's Castle appears in the credits, when the Toad Express drops the present through its roof.

Mario & Luigi: Partners in Time
In Mario & Luigi: Partners in Time, the castle is called Baby Bowser's Castle, since the Mario Bros. visit it in the past. The four heroes get to see a little of Baby Bowser's castle. The four Bros. practically reunite and start their adventure together there. Ironically, Baby Bowser is never seen inside the castle during the entire game, though the Mario Bros. discover a Cobalt Shard that he is keeping as a treasure. There is also a Time Hole here which links to Peach's Castle in the present. Oddly, the castle on the map in the presents looks exactly the same as the one in the past, so it still looks like Baby Bowser.

Mario & Luigi: Bowser's Inside Story
In Mario & Luigi: Bowser's Inside Story, the castle, here labeled as "Bowser Castle", is taken over by Fawful. Control of operating the castle is given to Midbus. After Bowser helps to fire a Banzai Bill at his own castle (taken over by this time), Midbus commands the castle to elevate, dogding the Banzai Bill and then to land on top of Bowser. Mario and Luigi must travel to Bowser's adrenal gland and cause Bowser to grow big enough to fight his castle, which is controlled by Midbus. 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 moved back to its original resting place. Later, Bowser attempts to gain access to the castle, however 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 after building up energy courtesy to Mario and Luigi, throws it back at the castle, damaging it badly enough to force it to land. Bowser then gains access to his castle, where he discovers that not only had Fawful brainwashed his minions, but had also turned the castle into a theater. In the meantime, Bowser decides to see the show Fawful puts on. A Goomba acting under the orders of Fawful had, however, tricked him into a VIP chair, which fires Bowser onto the stage, getting him stuck in a forced fight against Midbus.

After Bowser beats Midbus, Bowser is forced to eat a "victory feast" that Boos feed him. Later, he gets so fat from all his force-fed food that he gets stuck in the floor. After a strange hand grabs Princess Peach, Bowser falls through the floor, lands on a treadmill and catches on fire. Then, Bowser gets thrown into the Tunnel by lit up Bob-ombs.

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. However, Fawful had blocked up the path to his treasure stash and Bowser must push a Fawful statue off the castle balcony to break the barrier. However, his former minions begin to push against the statue too, trying to save the statue and push Bowser off the balcony. Mario and Luigi then must help Bowser push the statue. finally Bowser manages to go underground and get to his treasure vault, but the Monty Moles that had helped Bowser get to underground Toad Town earlier are now working for Fawful and are moving all of the treasure from the vault in the Fawful Express.

Curiously, the castle has a cold-storage vault, in which a large part of, if not the entire Shroob invasion force, is kept frozen, along with their princesses. If Mario and Luigi enter this room, which is not required to complete the game, they will fight three Shroobs.

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 containing Bowser, where after some disagreements, he and his paper counterpart decide to team up. They then kidnap their respective Princess Peaches and return to the castle. The castle's next appearance is in Doop Doop Dunes. Upon entry, the Marios (and Luigi) spot Bowser's Castle in the distance, which they must cross the desert to reach. Once close, the Bowsers notice and decide to blast the gang with cannonballs. The first shot misses them, but it does destroy the bridge connecting the castle to the desert. The second shot knocks them all out cold. Wendy, Roy, Larry and Ludwig arrive to take them to the Twinsy Tropics Dungeon and the Bowser Jrs collect the book containing Paper Mario's world.

Much later in the game, the group return to Bowser's Castle to rescue the princesses and get the book back. They learn the Trio Glider before encountering the two Kameks and Papercraft King Boo, who is controlled by Morton and Lemmy. Toadette 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 Jrs on guard duty.

The Princess Peaches then escape and greet the team, but are caught by the Bowser Jrs. They mean to fight, but realize they forgot to hide the book, so they flee. In a brief pseudo-minigame where the gang needs to catch the Bowser Jrs without being spotted by any minions, they catch them and force them to hand over the book, but they give them a decoy book and escape. The gang chases them down and engages in a battle with them, defeating them. Before they can get the book, the two Bowsers enter the room (expressing feeling towards the Bowser Jrs in the process) and taunt the gang before activating "the boosters". Bowser's Castle is lifted out of the lava moat and is dubbed "Neo Bowser Castle". The gang escapes, forgetting the book and the Bowsers retaliate for the Bowser Jrs' defeat by obliterating Peach's Castle.

Unlike other Mario & Luigi games, the castle's design is based on the Mario platformers 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 Bowser stone head anywhere, but instead it has a green Bowser-like emblem logo in the center. Further reflecting on the designs of canon 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 can no longer be explored, even when the game is completed.

Bowser's Castle is the only location in the game to contain lava, unlike most other games in the series.

Strangely, Bowser's Castle is the smallest area in the game, clocking in at only 9 rooms. It is lengthened by the papercraft stage and various objectives.

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
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 a villa there, which is considered to be another castle.

Mario Hoops 3-on-3
Bowser's Castle appears as a basketball court in Mario Hoops 3-on-3. The court has lots of dangers, such as Thwomps occasionally appearing out of ? Panels.The Thwomps will immediately, after coming out of a ? Panel, fall down to crush anyone who gets close. Also, Podoboos launch up from the lava and if any players touch them, they run around uncontrollably and on fire. Bombs do the same as well, but these ones are bigger. The music heard in this court is a cover of the Bowser's Castle theme from Super Mario Bros..

Itadaki Street DS
Bowser's Castle also appears as a stage in Itadaki Street DS, along with other stages from the Mario and Dragon Quest series. This Bowser's Castle is based on the one from New Super Mario Bros.. Players have to compete against Peach, Jessica and Bowser and place first to beat the board. Beating the board unlocks Bowser and Bowser's Castle.

Fortune Street
Bowser's Castle appears in the Itadaki Street DS sequel Fortune Street as an unlockable board map. Its appearance is similar to that of the previous game. There are doors on the top of the bigger section of land and one on the very top of the smaller section of land. The players can use these doors to navigate through the board. The doors bring players to the same spot each time they go through them. In Tour mode, the player has to play against Peach, Stella and Bowser while also coming in first to beat the board and unlock a new one.

"The home of Bowser. It's a minefield of tricks and traps where a single foot wrong could send you plummeting into a sea of molten lava."

Mario & Sonic series
Bowser's Castle appears in Mario & Sonic at the Olympic Winter Games as a location in Dream Ice Hockey. It also appears in Dream Figure Skating as the second stage to be faced. It consists of a giant stone Bowser head. There is also a lot of lava around the dream event.

Mario Sports Mix
Bowser's Castle is one of the fourteen courts of Mario Sports Mix and appears in all of the sports for the players to compete in. In volleyball and dodgeball, there are Podoboos which spring from the court and the limit of the two camps can displace which advantages one team has compared to the other one. In basketball, it is the same except for the absence of limits in the court. For Dodgeball, when players get knocked out, the center line will shift so that the losing team has more room to work with. For Volleyball, the leading team gets more room, but the losing team will be safe from all Podoboos; the Podoboos will pop up at the center of the Volleyball court.

Mario Tennis Open
Bowser's Castle returns as a tennis court in the game Mario Tennis Open for the Nintendo 3DS. It is a stone court built over a boiling lava landscape. Mechakoopas can be seen on the sidelines as spectators. A refereeing Toad is seen sitting in a cage outside the castle itself, where the normal referee's throne is. This court is where the Shell Cup takes place in Tournament mode. The music for this court is a cover version of Bowser's theme from Super Mario 64 and the Bowser Battle theme from Super Mario 3D Land.

"Bowser's fiery court built on boiling magma."

Area Tattles
Here is a list of Goombario's tattles in Paper Mario.
 * ''It's Bowser's Castle. This appears to be the hangar for Bowser's 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 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 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!

Trivia

 * Bowser's Castle from Paper Mario made a cameo appearance in the Mario Kart: Super Circuit course Rainbow Road.
 * 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 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 Burj Khalifa. However, due to the assumption that the castle should be merely 60 inches wide, it would cost only $455,000.
 * In Mario Kart DS, there is a bug where if one would start a VS. Race and would pick Bowser Castle for the first race, the position number would say seventh instead of eighth.
 * The music for the Bowser Castle courses in Super Mario Kart sounds very similar to the final boss theme from Super Mario World.
