Ook

Ook (ウーク, Uuku) is the miniboss of the Forest Temple in The Legend of Zelda: Twilight Princess. He is the leader of the Monkies, who in loyalty try to free Ook from a parasite. He is first seen when he cuts down a bridge across a chasm with the Gale Boomerang in the Forest Temple. Later, when Link enters his chamber, he will start spanking his bottom, mocking Link; then the battle begins. Dodging his boomerang is easy, but getting him down from the pillars that he jumps around on is a bit harder. After he throws his boomerang, Link must dodge it, then ram the pillar he is standing on. He will start to lose his balance and then get knocked off the pillar by his own boomerang when it comes back. Once downed, his bottom becomes vulnerable. After slashing at him a couple of times, he will cut some Baba Serpents down to attack Link. Once he is defeated, it is revealed that a gigantic mite on his head was controlling him. Defeating him will also yield the Gale Boomerang. After the battle, Ook will return to normal, and he later comes back to help Link battle Diababa, the dungeon's boss. He aids in the fight by swinging across the screen carrying bomblings for Link to use against Diababa.

Trivia

 * It is possible that the Yook in Phantom Hourglass are based on Ook, thus the similarity in name and appearance. Both also fight against Link at one point, but later become helpful.
 * The intro music to this mini-boss fight is a remixed version of Saria's Song.
