A graveyard ghoul attacks the audience during Nettles’ Horror Movie Night in the cemetery. The gang investigates and meet the owner of the cemetery, along with her three daughters. Fred and Shaggy become enamoured with them, while Daphne falls into a chocolate addiction. Velma and Scooby go alone to investigate, suspecting Evallo the gravedigger. Fred thinks it’s dumb of Velma to suspect the obvious suspect, but Velma ends up being right. Evallo was trying to steal gas from Crystal Cove. With the revelation of gas on the mother’s property, she becomes wealthy and decides she and her daughters will leave Crystal Cove. Cassidy begins a radio broadcast where she talks about evil in Crystal Cove. Mr. E and Pericles reflect and decide Cassidy must go.
