Scooby-Doo! and the Goblin King Shaggy are allowed to keep theirs as they have proven their courage. As morning comes, Fred, Daphne and Velma forget what transpired (due to the effects of the memory-erasing spell) as Shaggy and Scooby-Doo come to pick them up. As the carnival packs up, Scooby uses an unpacked mirror one last time to spook the gang as the film ends. Some monsters from "Scooby-Doo, Where Are You!", "The New Scooby-Doo Movies", "The Scooby-Doo Show", "Scooby-Doo and Scrappy-Doo", "What's New, Scooby-Doo?" and "Scooby-Doo! and the Legend of the Vampire" are sighted in this movie: Scooby-Doo! and the Goblin King Scooby-Doo and
Scooby-Doo, Where Are You! plans to create a non-violent Saturday morning program that would appease the parent watch groups that had protested the superhero-based programs of the mid-1960s. Originally titled "Mysteries Five", and later "Who's S-S-Scared?", "Scooby Doo, Where Are You!" underwent a number of changes from script to screen (the most significant being the downplaying of the musical group angle borrowed from "The Archie Show"). However, the basic concept—four teenagers (Fred, Daphne, Velma, and Shaggy) and a cowardly, clumsy Great Dane (Scooby-Doo) solving supernatural-related mysteries—was always in place. "Scooby-Doo" creators Joe Ruby and Ken Spears served as the story supervisors on the series.
