The episodes feature two protagonists, Stoppit and Tidyup, interacting with various other inhabitants of the mythical land of Do As You're Told.

The introduction theme music to Stoppit and Tidyup's friends coming along the screen at the start of each episode was "Follow the Leader" by Bobby Heath, Eric Peters and Robert Hunter from the Spectrum mood library.

Instead they gabble, grunt, squeak, click, make trumpet or raspberry sounds and hum whilst series narrator Terry Wogan unravels the tale for viewers.

The storylines are notable for their random, abstract nature, and the fact that an episode will frequently end without any moral message at all.

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.
