But he's forgotten that his mom is a total neat freak and can't stand the idea of having animals in the house. Can Freddy hide the hamster from his mom? And what will happen when the hamster gets loose and starts running around the house? (They always do.) Join Freddy in a typical first-grade adventure filled with humor!
