Baba Bud

Baba Buds are the bases of Boko Babas that appear in The Wind Waker. The first place these can be found is inside Forest Haven, where the Great Deku tree will ask Link to climb the area by use of the Baba Buds. Once he reaches the summit, Link will be granted with a Deku Leaf.

Although these buds can be found unoccupied usually, a Boko Baba will occasionally be guarding it. It should be noted that the actual bud and a bud occupied by a Boko Baba are slightly different colors. Often, by defeating the Baba, it will transform into a Baba Bud, although this isn't always the case. If Link hops into a bud, it will restore a slight amount of his magic power and launch him high into the air, giving him the ability to reach high places. By using the Deku Leaf, Link can utilize these powerful jumps to glide onto previously out-of-reach surfaces.

Trivia

 * Baba Buds have a similar function to the Deku Flowers from Majora's Mask. Unlike those flowers, buds can be used by anyone, not just Deku Scrubs.
