Monsters at Halloween, Paperback/Zanna Davidson

It's Halloween and Billy can't wait for the village Halloween Party. There's just one problem... his Mini Monsters are at the party too! Sparkle-Bogey's in the apple bobbing, Trumpet's in a pumpkin and Gloop's playing 'Guess the Body Part'. Can Billy find his monsters before anyone else does? Or will it be up to Peep to save the day?
