Timmy has to complete a book report during summer vacation, but the first day of Dimmsdale Elementary School is nearing, so Timmy wishes that Tom Sawyer would come out of his book and help him write his book report. Tom, being the lazy swindling type, steals Cosmo's wand and goes into a few well known books and edits them, forcing Timmy, Cosmo and Wanda to follow him. They now must end his antics before Tom rewrites the laws of physics.
