The Gorgs' secret password for the day is "I don't know the password."
While this was the fifth episode of Fraggle Rock that aired, it was the first episode to be produced, and served as the original pilot for the series. Jim Henson, CBC, and HBO wanted to see what the show would look like, and what problems could be changed. The reason it did not air first was because it was decided that it was not a proper introduction to the series; a more fitting introductory episode, "Beginnings," was produced later in the first season.
This episode was recorded on March 10, 1982. There was a gap between the production of this episode and the rest; the second episode shot, "Don't Cry Over Spilt Milk," was recorded in mid-April. Some of the puppets underwent slight redesigns in the meantime; most notably Marjory the Trash Heap and Sprocket.
Dave Goelz, the Muppeteer who performs Uncle Traveling Matt, makes a cameo appearance in Matt's scene. When Matt boards a roller coaster, Goelz is sitting next to him, performing Matt. Goelz has a false arm on the back of the roller coaster. Pay close attention to the shot in which Matt stands up. The scene was filmed at Canada's Wonderland, a theme park in Maple, Ontario, just north of filming headquarters in Metropolitan Toronto. The park was relatively new, having opened in 1981; Wild Beast was one of the original rides at the park.
