Ox goats appear to live in cold, desolate and open spaces of the Northern Water Tribe. Ox goats behave like most bovine creatures living in herds and grazing on grass. They also seem to be easily startled.

History
They were first shown when Noatak, under the harsh tutelage of his father Yakone, used bloodbending on them. He did so with ease, and ignored the squeals of pain from the animals he was controlling.

Connection
The Ox goat seems to be a cross between a Musk ox and a goat. Ox Goats are very large animals with long brown and white hair. They have two small horns on the top of their heads and lengthy tails.

Trivia

 * The Ox goat is the first animal Noatak is seen bloodbending and the second of three animals to be ever bloodbent. The first beeing an elephant rat, and the third being the wolf.
 * The Ox goat seems to make a similar sound to a Sky Bison.
