Bunny Hood

The Bunny Hood is an item used by Link in The Legend of Zelda: Ocarina of Time and The Legend of Zelda: Majora's Mask, both for the Nintendo 64. It also appeared as an item in Super Smash Bros. Melee and Super Smash Bros. Brawl for the GameCube and Wii, respectively. In Ocarina of Time, the only purpose of the Bunny Hood was to sell it to The Marathon Man. In Majora's Mask, it served a greater purpose, granting Link the ability to leap farther and run faster.

The Legend of Zelda series
The Bunny Hood first appeared in The Legend of Zelda: Ocarina of Time for the Nintendo 64. In it, the Bunny Hood could be worn by Link but the only effect it had was preventing Stalchildren from appearing at nighttime. It is the only mask in the game that has any effect when worn. If the player wears the Bunny Hood when talking to The Marathon Man, he'll offer to buy it from him and fill up his pouch with Rupees. In The Legend of Zelda: Majora's Mask, the mask will allow Link to move extremely fast and jump farther than he normally can. Finally, the Bunny Hood appears behind Carlov in the Nintendo Gallery in The Legend of Zelda: The Wind Waker, though Link is unable to wear it in this game.

Super Smash Bros. series
The abilities the Bunny Hood gave Link in Majora's Mask were brought over to the Super Smash Bros. series starting with Super Smash Bros. Melee. In the games, the Bunny Hood lasts for about 12 seconds before its effect wears off. A mode is present in Super Smash Bros. Brawl that puts the Bunny Hood on all of the characters for the entire match (without the effect wearing off). In both games, a trophy of the item appeared.

Trophy descriptions
Super Smash Bros. Melee
 * "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."

Super Smash Bros. Brawl
 * "Headgear that hugely improves your jump and movement abilities. True to its name, the hood comes with a pair of cute, fuzzy ears. On the right characters, they're as cute as can be, but on the wrong ones, they're...scary. Of course, that adds to the item's charm. The sudden speed increase you get is responsible for more than a few self-destructs, so be careful."
