Elmer the patchwork elephant must come to the rescue when all his jungle friends notice that the rainbow has lost its colors. Elmer makes his way through the jungle, asking his animal neighbors for advice on finding the end of the rainbow. When he finally locates it in the waterfall, Elmer enters the waterfall to share his colors, much to the concern of friends who worry that he’ll lose them in the sharing, but as Elmer informs them, “Some things you can give and give and not lose any. Things like happiness or love or my colors.” The books is sweet and colorful, and reunites readers with beloved characters, while teaching a philosophical truth. It’s a charmer.
