Traveling in his open-air Chimpmobile, the Cat takes Nick and Sally to Africa, Asia, and Madagascar, where they meet a barrel full of "monkeys," including mandrills, marmosets, gorillas, gibbons, gallagos, tarsiers, tamarin, pottos, bonobos—you name it! Along the way they learn the basic characteristics of primates (among them hands that can grasp and forward-facing eyes); how to tell the difference between an ape and a monkey (most monkeys have tails; apes don't); and most amazingly—that people are primates, too! Fans of the hit PBS Kids show The Cat in the Hat Knows a Lot About That! (which is based on the Cat in the Hat's Learning Library) will go bananas over this latest addition to the series!
