The Waddle Doos are small, orange, round creatures with stubby arms, and feet without legs, similarly to Kirby's species. They have no mouth, as their entire face is a single large eye protruding from the middle of their heads. They can attack by firing an energy whip from their single eye. Despite having no mouth, they can still speak.

They're not evil but they're tired of being bullied. So 1000 of them decided to band together to prove their worth to any who cross them!
