Charlie Bumpers vs. the Squeaking Skull

This Halloween Charlie and Tommy have big plans. They hope they can get out of taking their little sisters around and go trick-or-treating in Alex's upscale neighborhood instead. There they'll get tons more candy, they'll be on their own, and afterwards they'll get to attend the sleepover at Alex's house. But when Charlie finds out that the entertainment at the party is to consist of the "Scariest Horror Movies Ever," he is struck by panic. Charlie loves candy, he loves sleepovers with his friends, but he absolutely hates horror movies.
There is yet another wrinkle in Charlie's Halloween plans. He is determined to win the big prize (ten movie tickets) that will be awarded for the best costume, but when he finally comes up with a genius prize-winning idea, he runs into an unexpected obstacle?
How will Charlie be able to enjoy Halloween this year?
