Deku Nut
A Deku Nut is an item from The Legend of Zelda series, that also appears as an item in Super Smash Bros. Brawl. When thrown at an opponent, it will stun the opponent for a few seconds. The effect is similar to a player breaking another player's shield (or their own). It is possible for the thrower of the item to also be stunned during the explosion of the Deku Nut. If players are in mid-air during the explosion, they will be blasted away, similar to Bob-ombs. Deku Nuts will also explode on their own if left alone for a while. In The Legend of Zelda series, starting with Ocarina of Time, they can be used to stun an enemy.

Items that explode in a flash of blinding light shortly after they appear or when they take damage. Those caught in a blast will be dazed and immobile for a few moments. If the item is thrown, it has the same effect on whomever it hits. In The Legend of Zelda: Ocarina of Time, Deku Nuts stunned enemies and were indispensable when Link was surrounded.
