The elephants are not very happy: the hippos have come to live in their river because their own has dried up. When the elephants complain to Elmer that the river is over-crowded, Elmer sets off to see what he can do. He soon discovers that the problem can easily be solved, but only if the hippos and the elephants work together!
One day, as Elmer is strolling through the jungle, he hears a cry for help. A butterfly has been trapped in a hole by a fallen branch. Elmer rushes to the rescue and frees her with ease. In return she promises to help Elmer should he ever need it. But just how can a butterfly ever help an elephant?
