Continuity mistake: After the mystery is solved, the gang are driving away in the Mystery Machine. Shaggy and Scooby are in the back marveling at their wax dummies. Velma, Daphne, and Fred are in the front seat and can look back at them. But when it shows an angle from in front of them, the inside of the van behind Fred, Daphne and Velma can't be seen, only a solid gray wall where you should see Scooby, Shaggy, and their dummies, and even the back doors of the van.
Continuity mistake: When the Hooded Claw tries to kill Penelope, by tying her to a stage coach that is calculated to hit the passing train, The Anthill Mob end up on the track. The train runs them over which flattens the car and Pockets uses a spatula to get the car off him. When the car pops back into its original shape, Pockets is supposed to be lying flat on the railroad, but he can be spotted in the car.
