Curly gets in trouble enough already, but when the monster in the cupboard turns out to be a mischievous little creature called a Fent, Curly is about to find out where the trouble really starts! Adults can't see the Fent, so when the Fent tickles Curly in the car until he shrieks, and farts in the classroom, and eats Curly's dad's new invention, there's no one to blame but Curly. So unfair! But there's worse to come. Curly lives next door to the school bully and Billy can see the Fent too. Billy wants the Fent for himself. Can Curly save the Fent from Billy and get him home to his family?
