In a Monkee-type romp with Velma, Daphne, and a froglike moat monster, Davy sings "
I Can Make You Happy", a remake of the tune first heard in the original
Scooby Doo, Where Are You! episode no. 19, "Mystery Mask Mix-Up" (9/19/70).
The Haunted Horseman bears a striking resemblance to The Black Knight, the major protagonist of the original series premiere, "
What A Night For A Knight."
The following snippets from this episode can be seen in the opening titles:
- The Horseman and his horse charging.
