- Accidental Nightmare Fuel: Tidyup's honking voice, more specifically at the ending of each episode.
- Nightmare Fuel: The Sit-Downs, silent, unmoving creatures with blank white faces and pulsating black holes for eyes. They apparently had hypnotic powers.The Narrator: "Strange creatures that had been sitting there for as long as Stoppit and Tidyup could remember. Tidyup always expected them to do something else but they never did. All they did was... sit down."
- What Do You Mean, It Wasn't Made on Drugs?: They succeeded in making anthropomorphic personifications of the commands that parents give to children, of all the possible options.
- The Woobie: Poor little Calm Down. His episode takes place on a windy day with him being blown around by his umbrella, first towards I Said No's tree stump and then towards a group of children playing. And that's on top of being one of the few characters who starts off explicitly homeless.
YMMV / Stoppit and Tidyup
