The World Of Nothing is a white, lifeless world, eaten up by The Void. The World Of Nothing consists only of a road. Here the heroes face Mr. L, Luigi possessed by Count Bleck, with his new improved Brobot for a Pure Heart that was destroyed along with what the world previously was. A medieval-looking kingdom known as Sammer’s Kingdom.
After the game is beaten, the World of Nothing is restored back into Sammer's Kingdom, along with it's citizens and it's King. The player may then progress through this optional Chapter.
The world of nothing occasionally has random objects scattered around. Emphasis on RARELY!
