|Special World (unused world)|
|Game(s)||Newer Super Mario Bros. Wii|
|World number||F (unofficial)|
Special World is an unused world greatly resembling that of Super Mario World's Special World that was intended to be in Newer Super Mario Bros. Wii, but ended up being cut, supposedly due to time constraints and the impending release of the project. Unlike Cutland, the other unused world, there are actually levels that go with this world, but were also unused. As these levels were unused, they lack names. However, a user named mariomasters1 released the world, renaming all the levels and giving the world number the letter F.
