Starfy

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 younger sister, Starly. They all live in the Pufftop Palace but Moe also has a house of his own.

Only Starfy can perform the Air Jump, the Powerful Spin (which involves spinning with Moe, though it can be used when Moe isn't present, suggesting that the ability doesn't necessarily involve the real Moe), the Mighty Star Spin and the Ultra Star Spin.
