The silly title sets the scene for this funny fable of Foo Frog, Sue-Lin Salamander, and Mao-Mao Mudpuppy, who all began life on the same day in Washtub Pond. All is well until Foo grows bigger, always winning at tug-of-war and lily-pad wrestling. Not only is Foo’s body growing, but so is his head. “I must be the biggest animal in the whole wide world,“ he boasts. But when his friends observe an elephant at the pond and described it to Foo, the frog sucks in so much air that a puff of wind lifts him and carries him over farms, rice paddies, and animals—all of which appear small from above. His airborne superiority is quickly quelled by a great white heron, a fish, and a giant sea turtle. Finally back on land, he realizes that he is a small frog in a big world, but the perfect size for being friends. Gouache illustrations made up of buoyant, spontaneous, and comedic strokes match the exaggeration of this foolish frog. Booklist.
