Malcolm and Dandy may only be 10-year-old boys, but they've already experienced something most adults never do--a ghost! Malcolm's Ecto-Handheld-Automatic-Heat-Sensitive-Laser-Enhanced Specter Detector did its job at the McBleaky house. Malcolm is hoping his next gadget, the Ecto-Handheld-Automatic-Heat-Sensitive-Laser-Enchanced Ghost Zapper, will work on the ghost haunting the Millers' house!
