While the other monsters are ready for some summer fun, Talbot is stuck in summer school. Instead of doing the 20-page book report, Talbot finds a treasure map in the library and decides it is more important than school. He grabs the map, grabs his friend, and is ready for a big adventure. However, the adventure may be more than he can handle. Leaving summer school may be the worst mistake of his life!
