Ooccoo

Ooccoo is a small, bird-like creature with a human's head that is a very helpful ally of Link in The Legend of Zelda: Twilight Princess. She can warp Link to the entrance of the dungeon Link is in at any time (except during bosses and mid-bosses) and can warp Link back there in an instant. However, Ooccoo must always be found again in every dungeon, for Ooccoo does not follow Link around, but a soon as the boss is defeated, Ooccoo will go exploring, and is always in the next dungeon that Link explores, and is always trapped in a jar when Link rescues her.

Ooccoo Jr.
Ooccoo Jr. Is Ooccoo's son, and looks like Ooccoo's head with wings. He helps Link by travelling with Link every time he leaves the dungeon Ooccoo warped him out of, and warps Link back whenever Link feels necessary. He travels with his mother, and whenever Link pulls Ooccoo out of his pocket, Ooccoo Jr. Will take to fluttering behing and beside his mother's head.
