Korok

The Korok race is a race of wooden people with the ability to fly. The Koroks are known as 'The Children of the Forest' and are watched over by the Great Deku Tree, who resides in Forest Haven. The Koroks are said to have once been the race of humanoid children-looking creatures called Kokiri, but by the time they meet a young Link upon the Great Sea, they have taken on wooden bodies. The Koroks became these creatures when they gave up their human selves for the ability to fly, with the help of an item called a Deku Leaf.

Once a year, a select group of Koroks go out into the world to plant trees. This is done so that one day, the sea will retreat, and the Old Hyrule will be restored. This is preceded by a large ceremony, with music provided by a Korok named Makar. He remains in Forest Haven to practice this music for the entire year on his violin to prepare for the show. Meanwhile, another Korok named Hollo studies potion-making in an area of Forest Haven.

Korok Ceremony
