Bunny Mario

Bunny Mario is a form Mario can become in Super Mario Land 2: 6 Golden Coins by touching a Carrot. Bunny 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 lets him hover in mid-air. However, holding while on the ground causes Mario to hop continuously. Bunny Mario also cannot Spin Jump. In the second part of the final battle of Super Mario Land 2: 6 Golden Coins, Wario becomes and uses the same powers as Bunny Mario to battle Mario.

Bunny 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 the Super Smash Bros. series, players can pick up the Bunny Hood item, and gain a rabbit's ears, letting them jump higher and run faster. When Mario or Wario (in his overalls) wears it, he somewhat resembles his Bunny form.

Trivia

 * Bunny Mario could be parallel to Raccoon Mario, as they are both mammal-based power-ups that enable flight.
