Ugh! That was gross! Why does that exist?
|—Tulip, after exiting the Fart Car with One-One.|
The Fart Car is another train car featured in the pilot.
The inside of the car is a room with white walls, a white floor, and a white ceiling. The floor is shiny enough to show Tulip's reflection. This room is entirely empty, apart from farts that are seemingly created out of nowhere.
