Zippo is fed up with being an ordinary hippo. He wants to have a super power – something exciting, something amazing, something BIG! But being good at swimming and splashing in mud aren't considered superpowers. Perhaps he can learn to fly like his best friend Roxi the oxpecker. But who's ever heard of a flying hippopotamus? Especially one with such a big bottom . . .From the bestselling author/illustrator pairing of You're Called What?!, Kes Gray and Nikki Dyson, Zippo the Super Hippo is fantastically funny, and this big-bottomed superhero will be flying into children's imaginations everywhere!
