Flatchoo appears in the beginning of the film in a separate line of toys called the "Belch Brigade". His first appearance is a red ogre-like character. When pressing his stomach, he produces a burp and fart noise.
In the line of toys produced after the success of the film, Flatchoo was released as a member of the Gorgonites. The toy comes with an additional character, Nibble, which was never seen in the film.
- Flatchoo was originally going to be green but was made red instead.
- Some concept art of the Gorgonites included Flatchoo with green skin. This suggests that he was part of them in the early stages of the production of the film.
