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.
