Starfy is the main protagonist of The Legendary Starfy series. He is the Prince of the Pufftop Kingdom, along with his best friend, Moe the clam, and his sister, Starly, live in the Pufftop Palace. It is unknown whether he is a star or starfish, as the creators say he is "neither". He acts somewhat childish (for instance, when he is happy, he makes high-pitched squeals). He is 36 cm tall and 7 years old. He is voiced by Koorogi Satomi in Japanese commercials and The Legendary Starfy.
