Where's Casey? She's a prisoner of a living dinosaur-like creature in the Boston Science Museum! This is a case for the Monster Hunters! Edward Crane Jr. ("Numbles" to his friends) calls in his monster-hunting friends to help him find his six-year-old sister, Casey, lost during a sleep-over "Camp In" at the museum.
