- Hagglethorn Hall
- Subterranean cave
- The song used in this episode (I Can Make You Happy) was previously used in the episode Mystery Mask Mix-Up; in that episode it was performed by Austin Roberts.
- This is the only episode that features a chase scene that does not include Shaggy, and Scooby.
- Davy Jones passed away on February 29, 2012.
- After Davy falls down the stairs in the tin can suit of armour, Velma then insists on "helping him out of his outfit", right after the matter, Fred states "women! Go figure them out!" An interesting comment and situation made in a kids TV show.
Animation mistakes and/or technical glitches
- None known.
Inconsistencies/continuity errors and/or goofs/oddities
- This episode reveals that Fred has a nephew that was three years old at the time it took place indicating he has at least one brother or sister, but this hasn't been referenced since so it can hardly be considered canon.
- Shaggy is shown to be allergic to hay in this episode, but he functioned without issue in previous episodes that took place in a farm setting (like The Frickert Fracas), and in future episodes. The hay allergy is never brought up again making it a deus ex machina.
- Scooby's howling is also an example of a deus ex machina.
- After the moat monster's costume is destroyed and the gang tries to find their way out of the cave Velma states that before the costume was destroyed the person was hopping with their feet side by side and afterword ran like a human being with one foot in front of the other. The problem is during much of the chase the moat monster puts one foot in front of the other though he is doing it on all fours.
- Due to most likely expensive royalties owed to Davy Jones in lending his likeness and voice to to a fictionalised version of himself, Warner Home Video are unable to release this episode onto DVD.
