Plot
Velma gets a call from Cuthbert Crawley, a lawyer for Velma's family who tells her that she has inherited her great uncle's castle in Transylvania, Pennsylvania. At his office, Velma turns the offer down, replying that she wants nothing to do with her uncle, puzzling her friends. Mr. Crawley understands, revealing the curse over the estate. As the gang heads outside, Fred hears a noise from the Mystery Machine, then it explodes and a mysterious character with a mask appears. Crawley reveals that it is the ghost of the Baron, Velma's old ancestor. The remains of the machine explode again, with words saying "stay away from Transylvania", but Fred declares that is where they are going to find the person responsible for destroying the Mystery Machine.
Having no other option, the gang ride in the express. When pressured by the gang, Velma reveals the truth: her real last name is Von Dinkenstein, and the ghost is likely her ancestor, Baron Von Dinkenstein, who was said to have created a monster (which inspired famous novelist Mary Shelley to write her novel Frankenstein). All of a sudden, the train starts to pick up speed. After getting everyone to the last car, Shaggy goes to the front of the train, but finds not the conductor but the Baron's ghost who tears off the control panel before disappearing. The gang still manage to save the last car, the people, and themselves just as the train derails and explodes. As they arrive in town, the people in the car are the Inspector Krunch, the burgermeister and Iago. He takes them to the castle, where they meet Mrs. Vanders, the housekeeper. They arrive in the Baron's laboratory and find the created monster in solid ice. Perturbed by this revelation, Velma vows to recreate the experiment in order to prove that the monster is a fake and tells everyone else to leave. As the rest of the gang leave, Vanders shows Velma a machine which hypnotizes her.
Strange things start happening when the gang goes to a village festival.
