Rabbits of the Mushroom Kingdom, much like their "Real World" counterparts, are small, furry mammals with long ears and large hind paws. They're common in the fields and wooded regions of the kingdom. These animals also feature quite prominently in several Mario games.

 Nintendo Adventure Books
In Leaping Lizards, Morton Koopa Jr. sneaks into the palace, vandalizing it and transforming the Mushroom King into a rabbit with his Magic Scepter. Luigi's attempt to change the king back with the same scepter only makes matters worse, changing the king from a normal bunny into a human-sized one. In a later book, Unjust Desserts, Magikoopa sneaks into the palace garden with some enemies he had shrunk by shapeshifting into a rabbit.

 Super Mario 64
In Super Mario 64, a yellow rabbit named MIPS could be found in the basement of Peach's Castle. If caught, he would give Mario a secret Power Star. MIPS was found twice in the game, the first time time after collecting fifteen Power Stars, and the second time after fifty Stars.
 Super Mario 64 DS
In Super Mario 64 DS, rabbits feature much more prominently. They are found throughout the castle grounds (and their locations vary from character to character). The designated rabbits for each character have a specific color - yellow for Yoshi, pink for Mario, green for Luigi, and orange for Wario. If caught, they would unlock mini-games for the player to play in the Rec-Room. In Korean version, the rabbits for minigames do not appear because Korean version doesn't include minigames.

 Super Mario Galaxy
Though actual Rabbits do not appear in Super Mario Galaxy, a sub-species of cosmic Rabbits known as Star Bunnies appear in the game, however many of them are simply Lumas in disguise. Real ones, however, can be found in Galaxies such as Space Junk, Snow Cap, and, most notably, Gusty Garden. These star bunnies act very similar to MIPS in Super Mario 64, with the exception of that they appear to find it much more fun to be chased.
 Super Mario Galaxy 2
In Super Mario Galaxy 2 numerous Star Bunnies can be found inhabiting the Freezy Flake Galaxy and one can later be found on the Starship Mario. The secret mission in Cosmic Cove Galaxy also involves a Star Bunny. In this game, all Star Bunnies are real and none are Lumas.
