An untidy kid sets off a pest invasion like no other in this boisterously fun picture book about the perils of messy habits.

Playing and having fun is a kid’s job, right? Cleaning up is a parent's job, right? Why do grown-ups make such a fuss about tidiness and cleanliness, anyway? What’s the worst that could happen? A couple of ants pass through? A lone little mouse pays a midnight call? No big deal, right? Right? Author Jason Carter Eaton and illustrator Mark Fearing are here to caution you that being a slob might in fact be a big deal—a really big deal. Maybe even a BARBARIAN-size deal! This outrageously absurd cautionary tale might just make you think twice about the cupcake crumbs in your bed and the half-eaten cheese curls behind the sofa. After all, you could end up with an infestation of barbaric proportions!
