From the Super Mario Wiki
Rabbit Mario (also referred to as Bunny Mario) is a form Mario can become in Super Mario Land 2: 6 Golden Coins by touching a Carrot. Rabbit Mario has rabbit ears coming out of his hat. When Mario is in the air, holding can slow his descent, and repeatedly mashing it can lead to a quasi-fluttering of the ears which can keep him level in the air as he proceeds through the level. Also, holding while on the ground causes Mario to hop continuously. Rabbit Mario also lacks the ability to Spin Jump. In the second part of the final battle of Super Mario Land 2: 6 Golden Coins, Wario becomes Rabbit Wario and uses the same powers as Rabbit Mario to battle Mario.
Rabbit Mario appears in Mario Kirby Meisaku Video, a Japanese video starring Mario and Kirby. Mario uses his Rabbit form to fight Wario and his monoplane, the Bulldog.
In Super Smash Bros. Melee and Super Smash Bros. Brawl, players could pick up the Bunny Hood item, and gain a rabbit's ears, after that the player could jump higher and could run faster. When Mario wears it, he looks like Rabbit Mario.
