An expressive group of cheerful fish play follow the leader in their ocean habitat, unaware that a shark lurks in the background. Count the fish from one to ten as each joins the game, then count back down to one when the leader snacks on a sea spider and sets off an unfortunate chain reaction (swallow the leader!). Luckily for everyone, fish number ten—the shark—gulps down his prey too quickly, and burrrrrrrp! they all swim out again.        Lively rhymed text and energetic artwork combine in this exuberant counting book that’s sure to delight little ones learning their numbers.
