Bunny Hood

The Bunny Hood is a item in The Legend of Zelda: Ocarina of Time and more notably, The Legend of Zelda: Majora's Mask where it made Link faster if he wore it.

The Bunny Hood appears in the Marioverse twice in Super Smash Bros. Melee, and Super Smash Bros. Brawl. It allows the player to jump much higher and move faster than normal.

Interesting to note is that in Super Mario Land 2: 6 Golden Coins, the carrot item gave Mario bunny ears.

Trophy Information
''Don the Bunny Hood to improve your agility drastically, allowing you to jump great distances and move at high speed. The ears are a cute accessory: they're even adorable on characters they don't quite suit. The Bunny Hood was key in Majora's Mask, where it made Link move at one-and-a-half times his normal speed.''
