Hiyappu is the third member of the primate trio, and the representative of the water type. It shares its characteristics with the other monkeys, such as the large ears, mitten shaped hands, and the yellow color. Hiyappu also has a light-blue color, primarily on the head, but also on the top of the body, like a T-shirt which ends in a wave-like pattern. On the top of its head there is a large feature which is shaped like a fountain, or the water sprouted through whales’ blowholes. Like the other monkeys, Hiyappu has a tail that ends in a certain shape. Hiyappu’s tail ends in the shape of a clover, possibly also representing sprouting water. Its tail is the only one which is in the yellow color, but it turns blue for the shape at the end.
