The elephants decide it is their turn to play a trick on Elmer. They want all of the animals to pretend to forget Elmer's Birthday the next day. But when the time comes, the joke does not quite go according to plan.
Only Elmer the patchwork elephant is brave enough to investigate the strange roaring sound that sends the other jungle animals stampeding, and what he discovers comes as quite a surprise.
All the elephants of the jungle were gray except Elmer, who was a patchwork of brilliant colors until the day he got tired of being different and making the other elephants laugh.
