The elephants aren't happy, because the hippos river has dried up, and they moved to share the elephants' river. Elmer, the patchwork elephant, decides to investigate to see what happened to the hippos' river. He discovers that if the hippos and the elephants work together, they can move the rocks that fell that are blocking the hippos' river.
