Full credits

The following credits are how they are seen on-screen (or as close as possible).


  • "I Can Make You Happy", the song used in this episode, was previously used in the Scooby-Doo, Where Are You! episode Mystery Mask Mix-Up. In that episode, it was performed by George A. Robertson, Jr.
  • This is the only episode that features a chase scene that does not include Shaggy and Scooby.
  • This episode seems to bear a resemblance to the Scooby-Doo, Where Are You! episode A Gaggle of Galloping Ghosts, in that they both have castles that were imported from Europe to America. The latter in this case from Transylvania, and were meant to serve as tourist attractions until someone scared the tourists away for their own benefit.
  • 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.
  • Davy Jones passed away on February 29, 2012, at the age of 66.

Cultural references

  • Davy Jones was best known for being a part of The Monkees, a 1960s pop rock band created from its 1966-68 TV series of the same name. By the time this episode aired, the Monkees had already disbanded as a musical entity, yet Jones had already established international stardom as a teen idol. Incidentally, his friend and ex-Monkee, Mickey Dolenz, was already working as a voice-over artist for Hanna-Barbera, and would be a regular voice provider in the franchise's upcoming incarnation, The Scooby-Doo Show.
    • When Velma says he should "soothe the savage beast," Davy says he's never sung to a frog before, but he has sung to monkeys.
  • Shaggy mentions Henry VIII and Anne Boleyn. In English history, Henry VIII was king of England from 1509 to 1547 known for his six wives who were either beheaded or had their marriage annulled because they could not produce a rightful heir. Anne Boleyn (1501-1536) was his second wife who was beheaded due of her miscarriages.

Animation mistakes and/or technical glitches

  • When the Haunted horseman rides up to and into the barn he is transparent.

Inconsistencies/continuity errors and/or goofs/oddities

  • The title card spells Davy Jones' first name as "Davey", which is not how Mr. Jones was known professionally.
  • 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. Yet whenever Fred's family is brought up in moments throughout the various Scooby-Doo TV series and films, it's almost always implied that he's an only child.
  • 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.
  • It's still mysterious who exactly was hiding behind the white sheet in the music room. Did the Duke of Strathmore also have a henchman? Also, what was behind the secret door in the kitchen before the gang fell down into the cavern?
  • The song-and-chase sequence of the episode is written as Davy Jones attempting to use music to "soothe the savage beast" at Velma's suggestion. The end of the sequence places Mr. Jones hiding underwater breathing through a straw, a situation in which it would be difficult to sing properly. And somehow the Moat Monster wasn't able to follow the singing to his hiding place.
  • After the moat monster's costume is destroyed and the gang try 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 afterwards 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 usually doing so on all fours, there were times when he leaned back and used only his hind legs to move about.
  • While they were running away from the moat monster in the moat of the castle, Scooby and Shaggy can run/walk on water. This situation disobeys the law of physics since people cannot walk/run at water whatsoever due to the low density of the water.

Davy Jones: Velma, you're a genius.
Velma: You're just saying that for one reason. Because it's true.
