A group of cheerful fish play follow the leader in their ocean habitat, encountering crabs, whales, and rays along the way. Prereaders can count from one to ten as each new fish joins the game, then count back down to one when the leader snacks on a sea spider and sets off an unfortunate chain reaction; luckily for everyone, fish number ten—the shark— gulps down his prey too quickly, and burrrrrrrp! they all swim out again. Danna Smith's simple rhymes are well suited for beginning readers, and Kevin Sherry's chipper mixed-media illustrations keep the mood light and ensure that the shark isn't too scary for younger listeners.
