You probably already know what to do if you're happy and you know it, but in this cheerful book for prereaders, the monsters want to show how spooky they are! Filled with skeletons clapping hands, wicked witches stomping feet, hairy werewolves jumping up and down, sneaky vampires nodding heads, and naughty mummies snapping fingers, this book puts a different spin on Halloween, thanks to Jannie Ho's adorable renderings of some favorite creatures of the season.
