Korok

The Koroks are a race from The Legend of Zelda: The Wind Waker. They come from Forest Haven, but spend most of their lives away from it. They have wooden-like bodies (somewhat similar to Deku Scrubs) and wear what look like masks made from various types of leaves, although they could be their actual faces. Koroks are very light, and can travel on the wind by using sprouts as propellers. They make a hollow jingling sound when they move.

Most of the Koroks spend most of their lives far away from Forest Haven, planting the seeds of the Great Deku Tree; they only return to Forest Haven once a year, for the Korok Ceremony held when the Great Deku Tree bears seeds so they can take off again. The only Koroks that don't leave are Makar (who plays his little leaf violin at the ceremony and will become the Sage of Wind) and Hollo (who studies potion-making and uses Boko Baba Seeds to concoct his brews).

Theories
The Koroks were once perhaps the human-shaped Kokiri, but when Hyrule was transformed into the Great Sea, they took on a more plant-like appearance, and became even more fearful of other people. The Great Deku Tree says in the game, "Once upon a time, long ago, the Koroks took on human forms, but when they came to live on the sea, they took these shapes." One piece of evidence is that Fado, the Sage of Wind is closely connected to Makar, his replacement as sage. Interestingly, the Kokiri never grow up, and the Great Deku Tree refers to the Koroks as "my cherished little children".
