|This needs a stretch.|
A zombie ghoul attacks the cemetery, with the prime suspect being the grave digger, Evallo von Meanskrieg, who's a deadringer. But only Velma sees the connection, and has to expose the hoax by herself.
The mayor hosts a scary movie night at the cemetery, and shows a Vincent Van Ghoul movie, where he get turned into a fog ghoul. The movie gets interrupted by who a real ghoul who rips through the screen and scares everyone off. In the morning, the gang looks around for clues, but don't find anything significant. Velma gets spooked by the grave digger, Evallo, who looks much like the ghoul and even acts similar.
Instead of questioning Evallo, the rest of the gand decides to investigate a mysterious house near the cemetery. The house has a super-nice family by the name of Bjorklund living in it. The mother, Model, tells them how she moved there because she was trying to raise money.
Later, Velma is walking around looking for clues when Mr. E approaches her and asks her to help him again. She declines and walks away. After she leaves, Pericles tries to talk Mr. E, aka Ricky, into working with him again, saying that Cassidy is bitter, and that Brad and Judy are enigmas.
While Velma is out, the gang gets attacked by the Graveyard Ghoul in the Bjorklund house.
Mr. E thinks back to when he first met Pericles as a child, and how he nursed him back to health, becoming best friends.
Velma finds out that Count Evallo von Meanskrieg was rejected for a work permit for being "pure evil". When she tries to tell the gang, they laugh and say it can't be that obvious.
Velma goes off to look for clues again and gets ambushed by the Graveyard Ghoul in the cemetery.
Velma talks to Sheriff Stone and gets him to help her trap the Graveyard Ghoul. They find out that the Ghoul is using one of the crypts to hide a natural gas well. After a chase, they catch the Graveyard Ghoul, and find out that Evallo wanted to steal the gas to prove that he was worthy of his family's evil name. The mayor then reveals that the gas company next to the cemetery owes the Bjorklunds money for having unknowningly tapped into the gas field under the cemetery. When Mrs. Bjorklund sees how much money it is, she decides to move back to the old country she emmigrated from, as she and her daughters walk gleefully away. Then Sheriff Stone has to release Evallo for deportation as he has "diplomatic immunity."
Ricky and Pericles in the meantime, have decided to put the past behind them and work together to get the treasure, but first they must get rid of Cassidy.

- The recap also includes a never-before seen deleted scene from Web of the Dreamweaver!, in which Shaggy and the Sheriff spit Francilee's Cornbread Stuffin' on Scooby. This scene is an off-screen one, as the Sheriff says he was going to destroy that tasty evidence, as soon as Francilee Jackson was caught, with Scooby & Shaggy offering to help, while the rest of the gang questioned her.
