A creature that combines cuteness—large swirling eyes, a tiny mouth, and a body covered in fluffy white fur—with the intimidation of reptilian limbs, a tail, and a single horn on its forehead. It does not speak, but it sometimes laughs adorably with a "Fufu!" sound. It occasionally hunts prey like a cat... It is very attached to you and often clings to your arms or back. It is the size of a small dog.

A typical mermaid with a fish-like lower body, but its upper body is cat-like and mammalian (Nagano stated the model was an Inuhariko), and its hands are shaped like fish fins. While its appearance and way of speaking are cute, its nature is that of a monster or cryptid—unruly, relying on overwhelming violence, and selfishly judging everything by its own pleasure or discomfort. It is a fearsome being that cannot be understood at a fundamental level. True to its motif, it is skilled at singing and often sings songs of the island with a beautiful voice. It is attached to you and often lets you listen to its songs or sits on your shoulder... "Got it!! Got it!!" "Stop that weird song!" It likes strongly flavored foods and dislikes spicy things. It is the size of a small dog.
