Rabbit
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 field and wooded regions of the kingdom. These rodents also feature quite prominently in several Mario games. In Super Mario Land 2: 6 Golden Coins, Mario could become Rabbit Mario by eating a Carrot. While in this form, Mario could use his newfound rabbit ears to hover momentarily whilst falling or jumping.
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 Castle Secret Star. In Super Mario 64 DS, rabbits feature much more prominently. They are found throughout the castle grounds (their locations vary from character to character). The designated rabbits for each character have a specific color - yellow for Yoshi, pink for Mario, red for Luigi, and orange for Wario. If caught, they would unlock mini-games for the player to play in the Rec-Room. Special white, glowing rabbits needed to be caught to unlock a white door in the Character Door room, behind which was a Castle Secret Star.
