A Gaggle of Galloping Ghosts - S1-E11
Plot hole: There's no way the gypsy man could have shifted between the three forms of a Dracula look-alike, werewolf, and zombie man so quickly all over the place.
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)
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.
