 Jack Fenton s new gadget, the Fenton Crammer, is designed to shrink ghosts in both size and power. Unfortunately, it works on humans too, and when it accidentally goes off, it catches Danny (Phantom) in its wake, in addition to Dash (who s been assigned to help Danny train for Phys. Ed.) and Skulker. Now, Dash and Danny must work their way through the miles of yard and linoleum to get to the Crammer before Skulker gets to them - and before Danny s powers short out completely and reveal his true identity!
