Paper Mario: Color Splash is a Paper Mario game released for the Wii U on October 7, 2016. The game is a sequel to the 2012 game Paper Mario: Sticker Star for the Nintendo 3DS. It was the final Mario game to be released for the Wii U.
- Mario is able to wield a Paint Hammer, a weapon that's been given the power to create multiple colors of paint. Using it, he can recolor "white spots" where Slurp Guys have sucked up the color.
- The Paint system is introduced. Mario has a limited amount of paint in reserve, which he uses to color "white spots" or color Battle Cards in battle. He can gain more paint by collecting paint droplets in the overworld.
Mario and Princess Peach receive a letter from Prism Island, which they discover is a color-drained Toad. They sail to Prism Island with another Toad to investigate. Upon arriving at Port Prisma, the three travelers find the town deserted and notice colorless spots and objects. The central fountain is dry and missing its famed Big Paint Stars. A vault appears in the fountain, containing a paint can. After Mario tries to open it, the can is revealed to be Huey, Prisma Fountain's guardian. Huey explains the fountain is usually powered by six Big Paint Stars, which supply the island with infinite paint. He asks Mario to help recover them and save Port Prisma.
Mario traverses six areas to retrieve the Big Paint Stars while helping the local Toads and fighting various enemies, including the Koopalings, who serve as bosses. As Mario collects the Big Paint Stars, they incrementally reveal their memories of the attack on Port Prisma. Once Mario recovers all six Big Paint Stars, they reveal Bowser attempted to dye his shell using the Prisma Fountain, but inadvertently created black paint, a toxic substance which possessed him and transformed him into Black Bowser. He proceeded to steal the Big Paint Stars and drain the color from Prism Island. It is also revealed that he was the one who sent them the color-drained Toad in order to coax them to come to Prism Island.
With the help of Luigi and the Big Paint Stars, Mario and Huey reach Black Bowser's Castle. They discover he is mass-producing weaponized black paint, aiming to paint the world black. Mario and Huey halt the factory's operations, defeat Black Bowser, and rescue Peach. The factory's destruction causes the castle to fall apart. Peach, Mario and Luigi escape, but Huey stays to stop the black paint and absorbs the castle. Huey flies into space, taking the black paint far away from Prism Island and releases the black paint where it will cause no harm. In a post-credits scene, if the player has filled certain requirements, Huey will be seen falling back in the Prisma Fountain.
