Life for the little hippos is always the same: diving and swimming to their hearts’ content. Except the hippos think that it would be more fun if their diving board could be higher, as high as Tall Cliff. But they’re not allowed to go to Tall Cliff because it’s too dangerous. Each day they ask if they can, and each day they are told no. Finally, one day they are allowed to go there to bathe – cheers and jubilation. They are happy and hungry when they are swimming home, and they completely forget to watch out for trouble.
