In this classic from Robert Crowther, readers can lift the flaps and pull the tabs to find any number of surprises. (Ages 3 and up) One spider descends on its thread. Nine bees fly up from their hive. Twenty snakes slither. In a pop-up counting book certain to engage young readers, each kinetic collection of creatures illustrates a number from one to twenty --then by tens, all the way up to one hundred.
