Ook

Ook is the mini-boss of the Forest Temple in The Legend of Zelda: Twilight Princess. He is a baboon armed with the Gale Boomerang.

He first appears when he slices a bridge off with the boomerang. Later in the game, he is fought. He jumps around the arena, pillar to pillar, and taunts Link with his butt. Link must roll into his pillar when he throws the boomerang, which will make him lose his balance, and he gets hit with his own boomerang. He is knocked to the ground, and the player must slash his butt. After awhile, he is defeated, and a parasite falls off his head and dies, revealing he was being brainwashed. He runs away, and you take his boomerang.

He later helps the player by delivering bomblings to Link during the boss battle with Diababa.
