- Jerry Lewis
- Evil Ghost
- Chuck Vanderfleet
Clover is forced to babysitting Chucky, the obnoxious son of her mother's best friend, on Halloween night, but luckily she is able to rope Sam and Alex into hanging out with her so it will not be such a drag. The girls take Chucky trick-or-treating in the eerie gated community he lives in, but none of the neighbors seem to be home. They find out that the neighborhood is associated with a curse, which manifests itself after Mandy summons a spirit. The inhabitants are turned into ghouls bent on destroying the spies. Clover unwillingly becomes a hideous ghoul, undergoing another painful transformation, and Mandy becomes the ghost's queen! Can Sam and Alex survive the zombie attack and turn things back to normal before Chucky's mother gets home? In a b-story Jerry is going to his first ever Halloween party and seeks the girls' advice on costumes.
