Storo is a big, bulky, blue pirate mouse who wears a red headscarf, a sleeveless shirt, and an eye patch in the Squeaks. He acts as the muscle of Daroach's gang. Due his giant size and strength, it's very hard to knock him out, which is a challenge to submit this huge mouse. His attacks mainly involve smashing Kirby (for example, Storo wields a hammer and tries to smash him with it).
As with the other Squeaks, Storo is weak against fire, electricity and ice. When he is hit, he drops (presumably) stolen food.
