Sherman Oak and the Magic Potato

On the last day of school, Sherman Oak is given an atomic wedgie in front of hundreds of cheering students. Upon returning home, Sherman wishes for courage. A plain baked potato in an aluminum foil wrapper explodes with green light, and grants Sherman his wish. Sherman Oak is taken away against his will to a strange land. There, he must complete a journey filled with mosquito skeletons, snakes that wind from the sky, a haunted cottage, cactus outlaws, and a one hundred foot pus-oozing behemoth. If Sherman fails, his family and school mates will remain trapped in the land forever.
