 The storylines are notable for their random, abstract nature, and the fact that an episode will frequently end without any moral message at all.For example, in the twelfth episode, "Clean Your Teeth", it begins to snow in the middle of summer, and Stoppit gets left behind on his own while Tidyup and Clean Your Teeth spend the rest of the episode playing on sledges at the end, even though he loves the snow.Unlike its predecessor, "Stoppit and Tidyup" was cel-animated, and while a single episode of "The Trap Door" would take Charles Mills and Terry Brain an average of two weeks to write, build and shoot in 1984, a single episode of this series would only take them an average of ten days to write and film in 1987.
