It is a minor cutscene.
After beating Level B-9, a drawing of a teapot will appear on the map. When clicked on, a cutscene will begin in Level A-2 featuring an argument between the Runner and the Pastafarian. The Pastafarian had drawn a Teapot on the Runner's map, saying that it was missing.
The Runner asks her to only doodle things that exist, but the Pastafarian insists that the Teapot does. The Runner asks if she can see it, but the Pastafarian tells her that it is too small to see. The only reason she gives for its existence is that "The Flying Spaghetti Monster places a teapot in every solar system." This cutscene can be viewed again by clicking on the teapot drawing on the map.
If you look carefully in the background of this level, you can find the Child hiding in the background, spying on the two characters' conversation.
- The teapot is a reference to Russell's Teapot, a hypothetical teapot floating around in space.
