Don Knotts' second- and final- New Scooby Doo Movies guest appearance, following "Guess Who's Knott Coming To Dinner."
Unusual split-up, where Fred takes Velma, leaving Daphne behind with Shaggy and Scooby (and Don and the Sheriff.) All of the dialogue between Daphne and the sheriff at the window, and Shag, Scoob and Don under the table were cut by Cartoon Network to make room for a cartoon short at the end of the show. Fred and Velma are seen leaving together and finding the tire tracks, but then the rest of the gang is suddenly there, making it seem they had all left together one time. Scooby also goes with Daphne in the cemetery.
The following snippets from this episode can be seen in the opening titles:
- Scooby and Shaggy fall down a cave.
- Scooby and Shaggy rides down in a mine cart.
