Wonderworld is inspired by both the movie Westworld and the TV series Fantasy Island. The idea of a themed park inhabited by robots who cannot harm the guests is clearly based on Delos from Westworld. Wonderworld's Latino host Mr. Marino is clearly inspired by Mr. Roarke from Fantasy Island as well as the guest's choice of fantasy to live out.

For UK broadcast and home video release, the order in which this episode appeared was swapped with Scooby-Doo and Scrappy-Doo: Strange Encounters of a Scooby Kind (1979).
