Boko Nut

A Boko Nut is a large nut that grows in the Forbidden Woods.

Uses
The Boko Nut grows on a special stalk, from which the nut can be dislodged. Link can pick one up and carry it around the room. Eventually, the nut will decompose and fall apart. A new nut will then grow in place of the old one. These nuts are heavy and can be used as blunt weapons to defeat enemies and are required to open a few doors. If a Boko Nut is out of reach, Link can use the Deku Leaf to blow it from its stalk. Boko Nuts are somewhat similar in appearance to Deku Nuts.

Trivia

 * It is possible for Link to grab a Boko Nut from the upper floors of the Forbidden Woods and drop down carefully with it to the lower floors to reach the room with the door leading to Kalle Demos without acquiring the Boomerang; however, as the Boomerang is required to obtain the key that leads inside, all this would serve is to open the room's Warp Jar early.
