Paper Mario: Color Splash

Paper Mario: Color Splash is an action-adventure, turn-based role-playing game for the Wii U developed by Intelligent Systems. It is the fifth installment in the Paper Mario series as well as the twentieth and final Mario game released for the Wii U. As a direct successor to the Nintendo 3DS game Paper Mario: Sticker Star, it expands on many gameplay elements introduced in that game. Its direct sequel, Paper Mario: The Origami King, was released for the Nintendo Switch on July 17, 2020.

The game follows Mario's adventure across Prism Island to collect the six Big Paint Stars after receiving a color-drained Toad in the mail. During his adventure, Princess Peach gets kidnapped by the possessed Bowser and sends Mario Holo-Peaches to inform him about Bowser's plans.

The gameplay is very similar to its predecessor and puts an even greater emphasis on the paper aspect. All characters now have white outlines around them and the battle system now requires Things for each boss fight. Additionally, Things no longer need to be brought back to the main hub to be used; they become cards as soon as Mario collects them. Many enemies from the predecessor return, while Dino Rhinos make their Paper Mario debut in this game, along with several new variants of Shy Guys, most notably Slurp Guys.

Story
One stormy night, Princess Peach and Toad meet Mario at his house to deliver a strange letter: a Toad drained of his colors. The stamp on the letter points to Prism Island, where the three travel to. Upon arriving, they find the deserted Port Prisma full of spots drained of color. They also meet Huey, a mysterious 3D talking paint bucket, and find the cause of colorless spots to be Slurp Guys using straws to suck the color out of things. Huey then asks Mario to squeeze him into paper form in order to use the power of paint to battle the Shy Guys and to repaint the colorless spots, including the local Toads. Discovering that the Big Paint Stars at Prisma Fountain are gone, Huey asks Mario to find them and return them to the fountain. However, the Koopalings are also on the island and have captured the Big Paint Stars, and Mario must find and defeat them.

The events that caused Port Prisma to be damaged and the black paint's creation are explained through the Big Paint Stars' memories, told throughout the game. Bowser had jumped into the fountain and mixed the paint together, wanting his shell to turn rainbow. This created black paint, which possessed him. The Koopa Troop attacked Port Prisma, stealing its paint and sending a Toad as a letter to get Mario and Peach to Prism Island. When she gets kidnapped, Peach sends Mario a series of Holo-Peaches, holograms of her telling Mario what Bowser is doing while she is captured.

After saving Port Prisma, Mario and Huey set out to find the red Big Paint Star. First, they pass through Ruddy Road and Cherry Lake, learning the Cutout ability and collecting 3D real-world objects called Things. They find out that Bowser has stolen the paint from the Crimson Tower, where Morton is keeping a Big Paint Star captive. To open the gate, they must find the three Chosen Toads: Justice Toad at Cherry Lake, Surfing Kinopio at Bloo Bay Beach, and the Mountain Sage at Daffodil Peak. Additionally, Mario learns about the Unfurl ability and assembles the green and purple Rescue Squads at Indigo Underground and Ruddy Road to help him reach more Mini Paint Stars. When all the Chosen Toads have been found, Mario defeats Morton at the Crimson Tower, painting in a large gate at Sunglow Ridge.

At Sunglow Ridge, Mario witnesses a black missile cover an area with black paint, which Huey cleans up while Mario's eyes are closed. Afterward, he searches for Prof. Kinopio at Château Chanterelle, and finds him at Mondo Woods. The professor gives Mario an Excavation Site Permit, which he uses to enter Marmalade Valley. Here, Mario finds the professor's pet Chain Chomp, Princess, and brings her back to Château Chanterelle. The professor is happy and gives him the Sharp Spike as thanks. The spike unlocks the door to Kiwano Temple, which Mario must pass through to reach the Golden Coliseum, where Iggy is holding the yellow Big Paint Star. Mario defeats Iggy in a stadium battle and the Big Paint Star repaints an oversized coin in Mondo Woods.

Next, Mario investigates the mystery of ghosts haunting the Dark Bloo Inn, and explores the hotel's garden to find their Teapot to appease them. This leads him to Violet Passage, where he helps out the yellow Rescue Squad while on a pirate ship. The Rescue Squad goes to the shrunken Sacred Forest to unclog a pipe. Here, Mario pieces together a Mini Paint Star and gains access to Cobalt Base, where he participates in Snifit or Whiffit. After this, Mario infiltrates Fort Cobalt to defeat Ludwig in his Super Ludship and Super Ludsub. The recovered blue Big Paint Star repaints the ocean at Violet Passage.

With the ocean restored, Mario has to join a ship crew and venture to Fortune Island to find the purple Big Paint Star. Using clues left behind by a legendary captain, they first pass through the Lost Sea. They stop at Vortex Island to calm down a whirlpool, then help out a lighthouse keeper on Lighthouse Island to light the way to Fortune Island. Mario makes use of parallel worlds on all three islands to find the treasure but is confronted by Wendy on Fortune Island before he can collect it. Defeating Wendy and collecting the Big Paint Star repaints a sinkhole at Mustard Café, which the café's owner falls into.

After rescuing the café owner from the hole, including escaping a Snifit jail, Mario hears of the Sunset Express train stuck at Kiwano Temple. The blue Rescue Squad help fix the broken tracks, only for the train to be damaged by a Big Thwomp. The Toads push the train to Toad Trainworks, where Mario repairs it. Next, the train goes to Tangerino Grill, where Mario cooks pizza for the Toads, and serves steak to a VIP customer who is later revealed to be Larry. Larry hijacks the Sunset Express, but Mario defeats him with the help of the Toad train conductor. The train stops at Starlight Cape, where Huey makes a wish for the orange Big Paint Star; once it is granted, the Big Paint Star restores an unpainted Draggadon at Marmalade Valley.

After taming him, Mario guides Draggadon through Redpepper Volcano and platforms his way through Redpepper Crater to its hot spring. After returning to Tangerino Grill to get the Magnifying Glass Thing, he battles Kamek in the Sacred Forest. This opens a path to the Green Energy Plant, where Mario ventures into a Super Mario Bros. 3-like world to find a Mini Paint Star. He assembles the last members of the red Rescue Squad at Mossrock Theater, and visits the Emerald Circus, at which he meets Lemmy. Mario defeats Lemmy atop the circus tent and saves the green Big Paint Star, which then flies somewhere unknown and paints Luigi's kart.

Upon rescuing all six Big Paint Stars, they create a path to Black Bowser's Castle, where Mario and Huey head off to via a kart ride from Luigi. Inside they discover a factory producing Banzai Bills loaded with black paint, similar to the one dropped on Sunglow Ridge. After destroying the factory, they escape the flood of black paint and find Bowser with Princess Peach drained of her colors. As Mario battles Bowser, Huey has himself turned back into his 3D-self to absorb the black paint off and defeat Bowser, who has no memories of the incident. Black Bowser's Castle proceeds to collapse as Mario restores Peach's colors. Mario, Peach, and Luigi return to Port Prisma while Huey stays behind to contain the black paint and release it where it cannot do any more harm, to the skies. Later, while celebrating at Port Prisma, Peach comforts Mario when he laments Huey's disappearance. When all Super Flags are achieved, Huey can be seen falling back into the Prisma Fountain in the end screen.

Gameplay
Paper Mario: Color Splash is an action-adventure RPG game that elaborates on the mechanics of Paper Mario: Sticker Star. It is based on Mario using the Paint Hammer to paint colorless elements, characters, and parts of the environment in order to progress in the game and collect both Mini and Big Paint Stars. When a course is completed, several new courses may become available at once, and the number-based course naming that was seen in Super Paper Mario and Paper Mario: Sticker Star is gone (the game features a world map like the latter, however).

Super Flags return as well, this time found in the main square of Port Prisma. The battles are based on Battle Cards that can be painted to increase their attack power. Said cards can be found in colorless spots, ? Blocks, by defeating enemies or by buying them at Prisma Cardware. Once used, cards are discarded, but it is possible to buy them directly in battle by using the Battle Spin. There are three types of cards. Basic Cards are used for various purposes, including attacking, healing, and replenishing paint. Many attacks are similar to those featured in Paper Mario: Sticker Star, with the hammer attacks now having a charging sign indicating at which point an "Excellent" attack can be obtained. Thing Cards, which do not deplete Mario's paint, are used to summon Things, both in battle and in the overworld to solve puzzles. Such cards can be obtained by directly squeezing Things into Thing cards. There is a shop in Port Prisma allowing the player to directly buy Things to squeeze them into Thing Cards, and there are Replica versions of Thing Cards that can be found as well. The last card type, Enemy Cards, are used to summon an enemy into the battle as an ally. They can be found by defeating an enemy. Only one ally can be present at a time, and the ally attacks the enemies in the current battle. When the enemies attack, they will position themselves in front of Mario to protect him, and they stay in battle until defeated. If an Enemy Card is used in a boss battle, it runs away.

At the beginning of a battle, Kamek can sometimes appear and either flip over or steal most of the player's cards. Once the battle is won, all the stolen cards are regained and additional coins are obtained as well. The number showing the HP of the enemies as well as the number showing the amount of damage dealt in HP are both missing, while the health of each enemy is shown in the form of color that is gradually drained starting from the bottom.

Both the use of the Paint Hammer and the painting of uncolored cards require paint, which is indicated by the three bars on the top-left of the screen. After winning a battle, defeated enemies can drop coins, paint, Battle Cards, and cardboard hammers called Hammer Scraps. Hammer Scraps exist in four different varieties and are worth either 1 point, 5 points, 10 points, or 20 points, depending on how shiny they are. Hammer Scraps are used to fill the EXP bar that increases the maximum amount of paint that can be carried by the hammer.

At the start of the game, Mario can only play one card per turn. During the course of the game, he unlocks the ability to use more cards per battle turn by collecting Card Max Ups from the Soggy Guy in Cherry Lake, helping the ghosts in Dark Bloo Inn, and the Kamek battle in Sacred Forest. Similarly, the maximum amount of Mario's HP is increased by collecting HP-Up Hearts that are obtained when the player saves a Big Paint Star. Each HP-Up Heart increases the maximum amount of HP by 25 and increases the power of the First Strike as well.

In order to gain additional coins, there are side quests and mini-games that can be played. One of them is finding Luigi who is hiding in some places, another is playing Super Roshambo against several opponents at the Roshambo Temples. Defeating The Shy Bandit on the world map also rewards the player with extra coins.

Furthermore, it is possible to use a move similar to paperization called "Cutout" in order to cut part of the courses. Likewise, the Flip technique from Super Paper Mario returns as well, in a course dedicated to Super Mario Bros. 3 found at the Green Energy Plant.

Locations
The game is set on Prism Island, shaped like a paintbrush, and on nearby islands shaped like drops of paint, which have been drained of their color. The locations are organized according to the game's seven main colors, with the three primary colors (red, yellow and blue) and the three secondary colors (violet, orange, and green) having four courses and a course with a main boss each. Port Prisma is dedicated to the game's three primary colors and Bowser's Castle is dedicated to the game's tertiary color, black. The map is colored in as Mario collects Mini Paint Stars, though it is not possible to view it completely colorless, as the world map is only unlocked after Mario collects the red Mini Paint Star from Port Prisma.

Prisma Museum


The Prisma Museum is a museum hidden inside of the Action Command Dojo where the player can deposit Battle Cards to unlock concept art in the art gallery. Additionally, for every area that is fully repainted, the player unlocks music from that level in the sound gallery. When all types of cards are deposited, the museum lights up and Toads start visiting.

Roshambo Temples


The Roshambo Temples are areas where Mario can play Super Roshambo for coins and Battle Cards. There are eight Roshambo Temples located throughout Prism Island. Roshambo Temples do not have any Cutouts, Things, colorless spots, Rescue Toads, or Mini Paint Stars. They are unlocked by collecting tokens after completing various levels. Additionally, the player can challenge the Rock Paper Wizard if they have beaten a chapter boss, who awards them an Enemy Card based on the Koopalings or Kamek for defeating him. If the boss has not been beaten, Mario competes against a generic enemy in the third match instead.

Piper's sidequest
When Purp is repainted by the water wheel in Port Prisma, a sidequest initiates. Every time Mario finds one of Piper's friends, the tree in the yellow district grows a small amount. After Bloo is found, the tree begins to wither and the four friends set off to find the Rainbow Carnation. After Yella is found, he tells the gang that he knew Piper died, and the tree begins to wither even more before suddenly ejecting a seed that Piper sprouts out of. Mario begins to fight it, only for the five Toads to stop him and tell Mario that the Ptooie is Piper. After this, the six can be seen near the entrance to The Crimson Tower playing around.

Nintendo eShop description
''A mystery is afoot on Prism Island and only Mario™ can solve it——by restoring the land's vanishing colors with his new Paint Hammer. Puzzling battles await, but never fear; there's always a clever way to dish out the powerful Battle Cards up his sleeve. These fresh layers of strategy make this one of the most action-packed Paper Mario™ adventures ever!''

''It all begins when Mario receives an odd letter in the mail and heads for the unknown in a small boat. What he finds is a series of hilariously mysterious moments, each a clue that inches him closer to answering the riddle of Prism Island. To restore its former glory, he must first rescue the Big Paint Stars. Luckily, Mario's new companion Huey has granted him the power of paint, which can be used to recolor the exotic locales he'll hit up on his journey. Examine environments for clues, revive color-drained Toads, and even participate in strange events like the game show "Whifit or Snifit." Whatever it takes to make a splash on Prism Island!''

Notable mistakes and errors

 * In the American Spanish version of the game, one of the battle quotes for any red Shy Guy swinging on a trapeze at Mossrock Theater improperly refers to the Emerald Circus as the "greatest show" in Port Prisma. Most other interlanguage versions of the same battle quote properly refer to the entirety of Prism Island instead.

Pre-release and unused content
The game features a concept art gallery where concept art is gradually unlocked by donating Battle Cards to the museum. The concept art allows players to see how the characters, objects, and settings were gradually changed during development. It also reveals two locations that were cut from the game.

The first location is the east side of Decalburg from the previous game, that would have featured new objects including postboxes, differently placed Coins and ? Blocks and, most importantly, a river with sewage pipes, that would have been possible to cross using a bridge to reach an area not present in Paper Mario: Sticker Star. The second one is an unused location similar to a temple in a mountainous area of a rocky desert, that would have featured blue torches and at least three buildings connected by staircases and bridges. Many warp pipes would have been present as well, as in the concept art five of them can be observed, of which four are in a row.

The unused location on the inside would have featured blue torches, cacti, sandfalls, broken walls allowing light to enter, drawings of a Coin, a mushroom, and a star on the walls, very high pillars, bridges made of sand blocks, and spiked pits, thus making it similar to Kiwano Temple, suggesting, along with the rocky desert setting, that this unused location might have been a preliminary version of said location.

Promotion
A game on the Play Nintendo website was released in 2016 called Paper Mario: Color Splash Trivia Quiz.

Critical reception
Upon being shown at the March 3, 2016 Nintendo Direct, Paper Mario: Color Splash received negative reception from some fans, the main complaint focusing around the game's similarities to Paper Mario: Sticker Star. Within hours of the game's reveal, a petition on ordered the game to be canceled, which TechRadar described as "a frightening example of how quickly, and harshly, we judge games we know next to nothing about."

Despite this, the game received generally positive reviews at release. Most critics praised the game's art direction and humorous writing, though the lack of original characters and still-simplistic storyline were points of contention. In addition, while several reviewers noted gameplay improvements from Paper Mario: Sticker Star, some elements still drew criticism, such as the battle system and linear level design.

Sales
In its opening week - October 10 through 16, 2016 - Paper Mario: Color Splash sold 20,894 copies in Japan. It left the top 20 after the week of October 31 with 37,093 copies sold. Famitsu reported the game as selling a total of 65,316 copies over its entire lifetime in Japan, making it one of the lowest-selling retail Mario games in the country.

Similarities to the other Paper Mario games

 * Huey is Mario's companion in the game, fulfilling the role of Tippi from Super Paper Mario and Kersti from Paper Mario: Sticker Star.
 * Huey turns himself into a Battle Card to help Mario defeat Bowser, similar to how Kersti sacrificed herself by turning into a sticker during the final boss in Paper Mario: Sticker Star.
 * Bowser returns as the main antagonist, like he was in Paper Mario: Sticker Star.
 * Also, the black paint controls Bowser and makes him more powerful, much like the Royal Sticker in Paper Mario: Sticker Star.
 * There is a level in which Mario must go on a game show.
 * Snifit or Whiffit returns from Paper Mario: Sticker Star with new games involving Battle Cards.
 * Mini Paint Stars function like the Comet Pieces from Paper Mario: Sticker Star.
 * Battle Cards replace stickers.
 * Jumps, Hammers, their Worn-Out variants, Line Jumps, Hopslippers, Iron Jumps, Eekhammers, Hurlhammers, Blazehammers, Fire Flowers, Ice Flowers, POW Blocks, Mushrooms, Tails, Spike Helmets, and Frog Suits all return from Paper Mario: Sticker Star.
 * Things from Paper Mario: Sticker Star return, including the Fan, Cat-o-Luck, Basin, Lightbulb, and the Hair Dryer, along with the Teapot, although it has a different appearance.
 * Like in Paper Mario: Sticker Star, Luigi can be found hiding in some levels.
 * Like the previous home console installments of the Paper Mario series, the game starts at the Mario Bros.' House.
 * Much like Paper Mario: The Thousand-Year Door and Super Paper Mario, there is a generic enemy character named Johnson. In the former games' cases, he was an X-Naut and a Koopa Troopa respectively, whereas in this game, Johnson is a Shy Guy.
 * Bowser's castle floats, like it does in Paper Mario and Paper Mario: Sticker Star.
 * A parade takes place during the ending credits, just like in Paper Mario and Paper Mario: Sticker Star.
 * Luigi leads the parade, just like in those games.

Differences from the other Paper Mario games

 * Lakitus are completely absent from this game, though they are mentioned by Luigi.
 * When fought, enemies say phrases to provoke Mario.
 * Parakarry makes no appearance in any form and is not mentioned in any version either.
 * As a result, this is the first game to not reference a partner from a previous game in any version.
 * A giant Blooper does not appear as a boss or mini boss.
 * There is no story-related recurring mini boss.
 * The HP of enemies cannot be seen and has been replaced by the color of the enemy draining, showing how much HP it has left.
 * The amount of damage inflicted on enemies can also not be seen.
 * There are no individual save files.
 * Players can only remove save data through the settings.
 * When Mario hits a Save Block, the game does not ask the player if they want to save, instead automatically saving the game by default.
 * The heads-up display (Heart Points and coins, and the Paint Meter in this case) no longer disappears after a short time when Mario does not collect anything or is hurt.
 * When Mario collects a coin, the counter only bounces slightly instead of flashing three times.
 * When Mario collects a Big Paint Star, his maximum HP increases by 25 points. Comparatively, in previous Paper Mario games, Mario's health only increased by 5 points at a time (either after leveling up or collecting an HP-Up Heart).
 * Unlike in Paper Mario: Sticker Star, where several Things can be used for the same puzzle, only one set Thing is required to change a level.
 * When getting a Perfect Bonus, it is no longer based on clearing the battle in one turn without taking damage, but rather not sustaining damage throughout the entire battle.
 * Characters and enemies in this game have a more papery appearance than in the rest of the Paper Mario series. They have a white outline, similar to Mario & Luigi: Paper Jam, and they have no shading on their colors.
 * This is the first Paper Mario game where Boos are enemies, but no Big Boo variations are present.
 * This is the only Paper Mario game to have only one shop, which gets updated throughout the game; other games have multiple shops found in different areas.
 * This is the first Paper Mario game to contain an unlockable post-credits scene.

References to other games

 * Super Mario Bros.: The Goal Pole makes an appearance in both the 8-bit sprite from this game which appears in Green Energy Plant and in Black Bowser's Castle. The Springboard uses this game's sprite in Green Energy Plant as well. A Toad in the audience of Emerald Circus throws the Super Mushroom sprite from this game and Mario uses his idle based on his sprite while he grows.
 * Super Mario Bros.: The Lost Levels: When Huey realizes that the red Mini Paint Star in Ruddy Road has lost most of its color, he exclaims, "What in The Lost Levels is going on here?"
 * Super Mario Bros. 2: The overworld music is rearranged, titled "Spinning-Door Game." The vases also make an appearance in Château Chanterelle. Wart is mentioned in the game by a yellow Toad at Sunglow Ridge.
 * Yume Kōjō: Doki Doki Panic: At the concert in Plum Park, Birdo sings the line "two hearts in doki doki panic," referencing her first appearance in this game.
 * Super Mario Bros. 3: The Angry Sun is mentioned by one of the Five Fun Guys during Toad and Go Seek, and again by the Roshambo announcer while introducing Green Pokey. The Green Energy Plant is based on this game. When accessing the level, the soundtrack during normal gameplay is taken directly from the NES game, although flipping to 3D mode has it play a slightly orchestral cover. When Mario and Huey confront Larry on top of the train and the latter explains his motives, he makes clear he is doing his actions regarding hijacking the train to get the orange Big Paint Star solely to make sure Bowser isn't upset otherwise, which is what Larry stated in the Japanese manual for the game. The Recorder from this game (which, in turn, is from the original The Legend of Zelda game) appears as its 8-bit sprite in Green Energy Plant and can be squeezed into a more realistic-looking Thing Card; when used, the original notes are played by the flute itself, and it has the same effect of summoning a whirlwind, while three other flutes play the "Coin Heaven" theme in the background. Additionally, to board the airship, Mario hangs on an anchor, similar to how he did in this game. The Shy Guy Stack in Cherry Lake, upon seeing Mario, says, "HA! It looks like your upper lip found a Tanooki Suit!" Peach also uses Holo-Peachs to send Mario tips during the game after beating the various Koopalings, similar to her letters from Super Mario Bros. 3. Also, like in that game, she'll be unable to send a message to Mario after all objectives have been completed, although for different reasons (in Super Mario Bros. 3, Bowser sends a letter in her stead stating he kidnapped her again. In Color Splash, her message is cut off via Black Bowser draining her color off-screen).
 * Super Mario Land: An arranged version of the credits theme is present in the Roshambo Temples.
 * Dr. Mario series: After talking to the injured Purple Rescue Squad member on Daffodil Peak, if the player talks to Huey before helping the Toad, he'll mention Mario part-timing as a doctor.
 * Super Mario World: Dino Rhinos return from this game.
 * Paper Mario: The jingle played when collecting a Big Paint Star is remixed from the first few notes of this game's opening theme.
 * Luigi's Mansion series: One of the Toads in Dark Bloo Inn references Luigi's role in these games, noting that he has dealt with paranormal activity before.
 * Paper Mario: The Thousand-Year Door: The running gag that originated from this game in which an implied grunt character is referred to as Johnson returns after being absent from Sticker Star. Additionally, Port Prisma has an almost identical layout to Rogueport, with a staircase leading to the square where the major collectibles of the game are put in place in Prisma Fountain, like in Rogueport Sewers. In addition, Peach sends messages to Mario like in that game, and was ultimately responsible for getting him to the main area of the game in the first place, and late into the game, she also has her message cut off due to interference from the primary antagonist. The Hero's Journal looks similar to Goombella's Tattle Log.
 * Super Paper Mario: Mario can use flip in the Super Mario Bros. 3 part of Green Energy Plant in a similar way to this game.
 * Mario Party 8: The Five Fun Guys troupe name originates from the Mario and Toad team name featured in this game.
 * Mario Party 9: Toad and Go Seek is named after a minigame from this game.
 * New Super Mario Bros. Wii: Iggy taunts Mario by slapping his behind, like in this game. A Junior Clown Car, which is shown to be Koopa Clown Car in concept art, is seen in the back room of The Emerald Circus.
 * Paper Mario: Sticker Star: Many of this game's elements and physics return. Photographs of the Yoshi Sphinx, a location in World 2, and Hither Thither Hill can be seen on the left wall in Dark Bloo Inn's lobby. Also, sound effects from this game are recycled. The music for Bowser's introduction is also the same music used for his introduction from the same game. When Mario gets a Big Paint Star, the music that plays when the area's color is restored is the same theme that plays when the flashbacks explaining how each of the bosses in that game got their respective Royal Stickers. Also, there are plenty of music tracks from this game that are remixed. The Koopalings' introduction themes were also taken from the Warning themes for the "Sticker Star" boss introductions. Snifit or Whiffit is also taken from this game as well. The fight against Wendy is a music-based fight similar to the Gooper Blooper battle in this game. Huey turning into a battle card mirrors Kersti turning into a sticker.
 * Mario Kart series: Luigi appears driving a Standard Kart modeled after the ones from Mario Kart 8. Additionally, the "Luigi's death stare" meme, which originated from that game, is referenced. Also, the title theme and the countdown timer to begin racing are taken from this game as well. Rainbow Road appears in the game and the music of that course is a remix from Mario Kart 64. When Luigi decides to floor it to rush to the castle despite its creepy appearance, he states that they should be careful because Lakitu will not save them this time around, alluding to how various characters in the Mario Kart series, if caught in various hazards (falling into water, quicksand, lava, or bottomless pits), are fished out by Lakitu and brought back onto the main course. After being beaten, Bowser asks Mario if he's at Black Bowser's Castle because they have a kart race scheduled for the day, referencing the Bowser's Castle tracks in the series. Just before leaving Black Bowser's Castle in the ending, Luigi reassures Mario that Huey is alright, mentioning that he fell off Rainbow Road lots of times, alluding to the difficulty of the courses in the game.
 * New Super Mario Bros. U: Similar to the ending of this game, the Koopalings and Bowser's last appearance before the credits was them and their already damaged airship crash landing. Unlike in this game, however, it crashing was not Bowser's fault, as it got hit by a stray firework. Morton Koopa Jr. has his Hammer (based on Mario's) and Roy Koopa has his Bill Blaster for their respective fights.
 * Captain Toad: Treasure Tracker: Draggadon makes his paper debut. After using the Basin Thing in Redpepper Volcano, a bump comes out of its head, just like in this game after a rock falls on it. Also, when this happens, Mario can ride Draggadon as Captain Toad does in this game. One of the yellow Rescue Squad members says they used "sophisticated Toad treasure-tracking technology" to track a stolen bone from Marmalade Valley to The Golden Coliseum.
 * Mario & Luigi: Paper Jam: Enemies can sometimes appear in stacks, just as the paper enemies do in this game. Also, the Koopalings have their first paper appearances, after it being foreshadowed by Roy and Wendy in this game.

References in later games

 * Super Smash Bros. Ultimate: The battle theme from Paper Mario: Color Splash appears in this game. Additionally, Huey appears as a Spirit, and Petea Piranha is mentioned in Piranha Plant's Palutena's Guidance.
 * Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey: In Bowser Jr.'s Journey, having Morton Koopa Jr. as a First Officer in the player's team changes the team's name to "More Tons", a phrase Morton uses in several of his dialogues in Paper Mario: Color Splash.
 * Paper Mario: The Origami King: This game runs on a similar graphic engine, with many character appearances and text box sound effects being reused. A Shy Guy with a straw appears in Shogun Studios. The music for Fortune Island plays when Mario meets Captain T. Ode. An image of Princess Peach's appearance from this game appears in The Princess Peach alongside images of her other appearances in the series.

Trivia

 * The seven main colors on which the game is based (red, yellow, and blue as the primary colors; violet, orange, and green as the secondary colors; and black as the tertiary color) are actually the colors of the Koopalings' Magic Wands, first introduced in Super Mario Bros. 3 in 1988.
 * On September 23, 2016, it was discovered that purchased Nintendo eShop pre-load data was actually the full game, granting players early access two weeks ahead of schedule in North America. Nintendo, however, removed the pre-order option within hours, and stated that this was inadvertent.
 * In some English-speaking countries (e.g. the United Kingdom and Australia), the correct spelling for color is "colour". Despite this, the title was not changed outside of the Americas to reflect this difference.
