The Carpet Plain is a 2-Player Mode map.
It has the indoor style that the Glutton's Kitchen displays; hold 'R' to see the walls of a house. The floor, as the name suggests, is covered in a grey and fluffy carpet, occasionally with plates or toy blocks on it. The borders of the level are made out of baseboards, bricks, trees and bump-like "bridges" that one can walk on. All of these objects are wooden, and most of them are painted in a variety of colours.
Enemies
Dwarf Orange Bulborbs, Sheargrubs, Shearwigs (under the yellow marbles) and two Puffy Blowhogs.
