Kokiri

Kokiri are the race of people that live in Kokiri Forest, next to the Lost Woods. Rumors about them are that they never leave the childhood stage, so it appears that they are children forever. The most famous Kokiri are Saria and Mido. At the beginning of Ocarin of Time, Link was living with the Kokiri in their village until the Gret Deku Tree sent Navi to bring him to a quest.

Although unconfirmed, there is a myth that the Koroks from The Windwaker were descendants of the Kokiri after the King of Hyrule used the Triforce to flood Hyrule to seal the evil forces inside the old land.
