Yook

The Yook are a hairy, club-wielding species that first appeared in Phantom Hourglass on the Isle of Frost. They seem to be based on the Yeti, something they share with the Zelda Universe Yeti found in Twilight Princess. They had bitter struggles with their enemies, the Anouki, but formed a peace agreement 100 years before the events in Phantom Hourglass. Now the Anouki inhabit the western side of the island while the Yook live in the Great Ice Field on the eastern side of the island. They will attack anyone they consider a threat, but display the fatal flaw of sucking in large breaths of air. This allows one to throw a bomb in their mouth which will temporarily stun them and make them vulnerable to attack. Some Yook have white hair, but others have black hair. White ones will defend more and attempt to inhale more often, but black ones swing with their club more and are generally better fighters.

During Phantom Hourglass, a black-haired Yook invades the western side of the island, kidnaps the Anouki, Aroo, and disguises himself as Aroo. This event resparks a strong hatred among the Anouki for the Yook. After Link defeats Gleeok in the Temple of Ice, the Yook claim that they were mind-controlled and they become more peaceable from then on.
