Unfortunately, the boys are captured by the humongous hamster hosts during a sightseeing trip to the Great Wheel of the Andromeda Galaxy.

Things go from bad to worse when the school's laziest hamster is charged with looking after Harry and Colin for the holidays. Will the adventurers find a way to escape from their hamster hell?
