Final Scooby-Doo episode to use a laugh track, which had been in place since Scooby Doo, Where Are You! (1969).
Lennie Weinrib's final performance as Scrappy-Doo. His voice was oddly not re-dubbed by replacement actor Don Messick for the opening titles, so subsequent seasons would continue to hear his voice despite Scrappy sounding distinctively different in the actual episodes.
This episodes acts as a full length 'Pilot' of sorts for the revamped short segment formula that was come in subsequent seasons, with Scooby, Shaggy and Scrappy becoming independent from the rest of the gang and encountering real criminals, monsters and foes etc rather than the traditional supernatural whodunit mysteries. As this was also Lennie Weinrib's final performance as Scrappy-Doo, it would mark the only occasion he would voice Scrappy in such a story.
Final episode to feature the entire Mystery Inc. gang. Daphne would return for The New Scooby and Scrappy-Doo Show (1983), and other than guest appearances, Fred and Velma would not be seen until A Pup Named Scooby-Doo (1988) (along with Daphne as their younger selves) and Scooby-Doo on Zombie Island (1998) as fully reinstated regulars.
First Scooby-Doo episode where the villains didn't wear monster or ghost costumes.
