Cat Mario

Cat Mario is a form of Mario introduced in Super Mario 3D World which he can transform into by using the Super Bell item. This suit is not limited to Mario, and can also be used by Luigi, Toad, Princess Peach, Rosalina and Bowser. Mario's suit is gold while Luigi's is lime, Peach's is magenta, and Toad's is blue, which match their colors (Luigi's suit, however, has rounded ears, a spotted body, and dark green ears and tail tip, making him resemble either a leopard, a jaguar, or a cheetah). Rosalina's is black, and resembles a tuxedo cat, while Bowser uses the Super Bell to become Meowser, the final boss of the game. In Mario Kart 8, Cat Peach appears as a playable character of her own in the first DLC add-on pack for the game.

Super Mario 3D World
The Cat Suit makes its debut in the Wii U game Super Mario 3D World. The ability is gained upon collecting a Super Bell. In this form, the player can climb up walls for a brief period of time as well as climb up the Goal Pole. The player also has the ability to pounce on enemies from midair to scratch them with their claws. The pounce is equivalent to a Ground Pound attack. Cat Mario can also scratch enemies from close up on the ground as well as slide into them. When running across ground, Cat Mario clings to the ground and runs at a crouching height. He also has the ability to spin Cat Wheels, similar to Tanooki Mario in Super Mario 3D Land. Cat Mario can also break into a sprint significantly sooner than with any other power-up.

The form is similar to Tanooki Mario and Flying Squirrel Mario as they are all based on animals and can be used to reach higher places. When Bowser becomes Meowser, he has white and orange fur with brown stripes, similarly to a tiger, a ringed tail, cat ears instead of horns, whiskers, and his nose is black. Also, his hair is colored red, white and brown, and his shell appears to become more blueish. Like Cat Goombas and Cat Bullet Bills, his form is similar to a transformation than an actual suit.

Obtaining a Lucky Bell lets Mario turn into another form of Cat Mario known as Lucky Cat Mario, which lets him turn into Golden Statue Mario, similar to Statue Mario from Super Mario 3D Land. Its appearance is similar to that of a maneki-neko.

Mario Kart 8
Cat Peach appears as a downloadable character in Mario Kart 8. She is part of the The Legend of Zelda × Mario Kart 8 DLC pack along with Tanooki Mario and Link, as well as four karts and eight race tracks. The Cat Cruiser also has a design that resembles Cat Peach. Cat Peach, along with the female Villager have more acceleration at the cost of their weight stat. They are the lightest middleweight playable characters in the game, being slightly lighter than Peach, Daisy, and the various Yoshis, but heavier than Toad, Koopa Troopa, the various Shy Guys, Lakitu, Toadette, Larry, Wendy, the babies, and Isabelle.

Puzzle & Dragons: Super Mario Bros. Edition
Cat Mario and Cat Luigi appear as leader characters in Puzzle & Dragons: Super Mario Bros. Edition. Cat Mario is a Dark/Fire attribute member that is unlocked by clearing ★World 3, and Cat Luigi is a Dark/Wood attribute member that is unlocked by clearing ★World 4. Both of these characters can be trained so they reach level 99, and have similar HP, attack, and recover ratings with only a few differences. Cat Mario's main skill is called "Cat Walk", and it can be performed once every 12 turns; it increases by 1.5, for one turn, the attack power of any team member that has the Dark attribute. He also has a leader skill, the "Bell Rhythm", which raises every member's attack power by 3.5 after performing six combos consequently. Meanwhile, Cat Luigi's main skill is "Cat Dash", which lets the player move freely any orb that is on-screen for 10 seconds. His leader skill is "Bell Tempo", and it raises the attack power of all team members by 5.5 after attacking with five elements (attributes) at once.

Trivia

 * When in Cat form, a jingling sound can sometimes be heard when the player jumps.
 * In an earlier version of Super Mario 3D World, whenever Mario transformed into Cat Mario, he would say "nya nya", which is Japanese for "meow". In the final version, this was changed to "Meow meow" instead.
 * According to Super Mario 3D World director Kenta Motakura, the reason for Rosalina's cat suit being black was by a request from producer Yoshiaki Koizumi.
