Happy is a small blue Exceed with a white stomach. He has a rectangular head, with pink ears, big black eyes with small, thin eyebrows, and light blue cheek marks near to his tiny whiskers (two on each side of his face). Happy has a triangular nose that leads to semi-round upper lips on the sides. His body is rectangular too, and being an Exceed, it has a structure that allows him to walk erect unlike normal cats. Despite having no thumbs, Happy is able to hold things. He has a long, white-tipped tail; and the other parts of his tail are blue.
