Deku Nut

Deku Nuts are recurring items in the Legend of Zelda series. These nuts have various purposes and functions depending on the game of their appearance.

The Legend of Zelda: Ocarina of Time
Deku Nuts are one of the first items obtained in the game, and are one of the few items that can be used both while Link is a youth and when he is an adult. When thrown, Deku Nuts release a blinding flash that stuns most regular enemies. Deku Nuts can be obtained by defeating Deku Babas, and are also occasionally found in Treasure Chests or shops. Sheik and Impa both use Deku Nuts to disappear, supposedly an oft-used escape mechanism among the Sheikah. Deku Nuts are notable for their ability to be used by Link without putting away his sword first, allowing quick stuns and follow up attacks.

The Legend of Zelda: Majora's Mask
Deku Nuts are arguably the first item obtained in the game; some Deku Nuts are found in a chest located in the tunnels beneath the Clock Tower. They retain their appearance and function from Ocarina of Time. While using the flying ability of Link's Deku form, they can be dropped with B, hitting unwary targets situated directly below Link. If used in this manner, the Deku Nuts will cause damage rather than stun. Deku Nuts may also be collected by rolling into certain trees in Great Bay, they are visible from the ground.

The Legend of Zelda: Twilight Princess
Deku Nuts are found in forest areas, for the most part. They can be broken apart, often revealing helpful items inside, such as Pumpkin Seeds, which are used as ammunition for the Slingshot. Additionally, Link can throw Deku Nuts directly at Z-targeted enemies for minor damage, automatically taking into account height and distance. By contrast, other objects such as rocks will have to be thrown at a set distance.

Super Smash Bros. Brawl
Deku Nuts occasionally appear, and can be thrown at opponents. If they are left alone, they will explode after a set period of time has passed. A direct hit causes massive knockback, stunning everyone caught within the blast radius (including the thrower) for a short period of time. Deku Nuts also appear as a trophy.
