From opposites to eating to laugh-out-loud humor, this terrific trio of books from Jane Yolen makes for a rollicking read. Gatefold flaps on every spread of How do Dinosaurs Go up and Down? engage readers, three dino cookie recipes in How do Dinosaurs Eat Cookies? make for engaging play and lift-the-flap answers turn How Do Dinosaurs Laugh Out Loud? into uproarious fun for the whole family.
