Storo is one of the Squeaks, and a reoccurring Mid boss in Kirby: Squeak Squad. He sometimes appears when Kirby obtains a large chest. As such, his main goal is to steal Kirby's chest and take it to his headquarters. Kirby can either run away with the chest, defeat Storo, or if Storo already obtained the chest, quickly go to the headquarters to defeat him. His method of attacking is either bumping into Kirby or hitting him with a hammer. He looks like a gluttonous blue squeak with a red hat, red shirt, a eyepatch over his eye, and his belly button sticking out. After he is halfway defeated, he turns red. At some point in the battle, Storo falls unconscious. At that moment, Kirby can repetitively attack him to obtain food (or possibly even Invincibility Candy). If Kirby attacks Storo while he has his hammer out, he may drop it, allowing Kirby to inhale it for the Hammer ability.
Storo also appears in Speedy Teatime as the main opponent.
He reappears in Kirby Mass Attack on the Squeaks' zeppelin but does not speak.
In Kirby Star Allies, Daroach can call upon Storo using the 'Summon Storo' move. When he appears, he leaps into the air, then slams straight downward three times in succession before disappearing. His slams can do a large amount of damage, and can also pound posts.
- In Kirby Mass Attack, Daroach reveals that Storo brushes his teeth until they are all minty fresh.
- In the main menu for Kirby Star Allies, one of the character interactions has Storo flattening Kirby as they pass. This is a reference to the intro for Kirby: Squeak Squad, where the same thing happens.
- Despite having an eyepatch, Storo's other eye is never visible either.
