Yook

In The Legend of Zelda: Phantom Hourglass, the Yooks are yeti-like creatures that inhabit the Isle of Frost along with the Anouki. According to the Anouki, the Yooks are liars and have been their rivals for a long time. However, about 100 years ago, the two tribes signed a peace treaty; although shortly before Link reaches the island, one of the Yooks has kidnapped and impersonated an Anouki. When Link initially enters their Ice Fields, they are hostile and attack him with clubs and icy breath, but after he slays Gleeok, the dungeon's boss, they become friendly and claim that they were under a curse.
