Excitement is brewing when a new costume shop opens near Ham's neighborhood. The shop is hosting a grand opening party and giving one hundred dollars to the best costume of the night. Everyone who's anyone in middle school is going to this party. Ham is determined to be there and to win the money so he can buy his new pet, a leopard gecko. Ham's parents say he can't go, but he and his best friend, Bucket, make a plan to get there and win no matter what. Ham's reputation is at stake, and he really needs that prize money! Plus, it's an opportunity for Ham to put his irritating neighbor and classmate, Foley, in his place. Ham will do anything to get what he wants. But this time, has he gone too far?
