One of these creatures ran loose in a Fire Nation bazaar visited by Team Avatar. After seeing the animal enjoy a meal of meat, Sokka was inspired to use it as a persuasive argument to coax Aang into entering a meat shop with them, referring to the animal while noting that even the meat ate meat. A flying, fire-breathing hippo cow carrying Fire Lord Ozai on its back appeared in one of Aang's nightmares. Several hippo cows were kept on a small farm not far from the capital of the state of Yi.
