Oocca

The Oocca are an ancient race of people, Ooccoo being one, that are rumored to have created the Hylians. Shad states later in the game that they are the ancestors of the Hylians. They live in the City in the Sky. They seem to resemble a bald chicken and can be used to float similarly to Cuccos. When they are picked up, they make high pitched, fast nonsense noises. The sound they make when merely walking seems a remixed version of the sound the Miniblins make in The Wind waker. The Oocca are also rumored to be somehow associated with the royal family and possibly be closer to the gods than the Hylians and Sheikah.

Early art for Ocarina of Time shows the Triforce being kept in a sky temple, which is still visible but inaccessible in the final game. The Twilight Princess dungeon City in the Sky may in fact be that temple, as it is in the same approximate location near Lake Hylia/Gerudo Desert. This lends credence to the theory that the Oocca were the original keepers of the Triforce.

Despite the fact that they squawk when picked up, according to Midna they do not mind and in fact are trying to help Link even if it means being picked up like a toy.

The Oocca seem to be based on M. C. Escher's painting "Another World" which includes similar birdlike creatures.
