|Previous world||(8) Koopa Planet/Core (?)|
Special World (also known as Bonus Land) is the ninth and final world in Newer Super Mario Bros. Wii. It is a mishmash of themes only unlocked if the player has completed Bowser's Keep and collected all 354 prior Star Coins.
Special World has no bosses.
Special World itself is portrayed as a circle of ten blank Newer logos, color-coded according to the rainbow with some exceptions, all around a Newer logo in the middle. It is set in a green checkered seemingly alternate dimension accessed only through a Newer-themed futuristic teleporter. The levels themselves, however, are several different themes corresponding with their color on the world map.
Special World can only be accessed through completing Bowser's Keep in Koopa Core and having collected all 354 prior Star Coins, which will unlock a pathway from Yoshi's Island. Completion of Black Clappers grants access to a shortcut to Red Lava, leading nowhere new and signaling the ending of the game.

- Six of Special World's levels—Red Lava, Orange Prairie, Yellow Beach, Mossdeep Greens, Blue Chilldesert, and Navyblue Molemine—have inaccessible secret exits that may possibly be linked to the unused Special World. It is likely that these secret exits were required in order to move on from the normal Special World to the unused one, in a manner similar to the Special Zone in Super Mario World.
- It is unknown whether or not the other four levels in this world were intended to have secret exits. It's possible that they were intended to have secret exits, but the idea was scrapped before they were completed.
