1 continuity mistake in What the Hex is Going On? - chronological order
Starring: Frank Welker, Don Messick, Casey Kasem, Nicole Jaffe
Revealing mistake: After Mr. Maxwell says that the local people refuse to work on the movie, Velma asks why. In her close up, her right pupil is horribly misshapen. Not round, but a wobbly, almost cloud like shape. (00:01:35)
Don't Fool With a Phantom - S2-E8
Shaggy: Hey, Scoob, aren't our wax statues the greatest?
Scooby: Yeah.
Daphne: Just what are you fellas going to do with those wax dummies you made?
Shaggy: Well like simple, next time we have a mystery, those dummies can go instead of us.
Fred: There's only one problem. How to tell one pair of dummies from the other.
Shaggy: Very funny, very funny.
Scooby: Yeah. Rery funny.
Trivia: During the chase scene, there is an advert on the wall which says "H&B Tuna Co." - a reference to Hanna-Barbera.
Question: We never found out what the ham and chicken bones had to do with anything. They were ham and chicken until Scooby ate them. Afterwards, Shaggy wonders why the ghost would keep ham and chicken in the fridge. This was never answered in the episode. Why were they important?
Answer: Shaggy told the gang he found ham and chicken in the fridge. He said, "Why would a ghost need food?"
Chosen answer: A ghost wouldn't have to keep any food in the fridge - they don't need to eat. So it is one thing that proves the ghost is not a ghost.
