Sky City, or World C, is the third secret world in Newer Super Mario Bros. Wii. It is unlocked by completing the secret exit in World 4-A: Hilltop Town. Completing the tower will unlock a shortcut to World 7-2: Paratroopa Peaks. This is the fastest way to finish the game. Unlike other secret worlds it has a tower instead of a fortress. This world is based on Star Wars and Back To The Future and the music is Nimbus Land from Mario RPG. Save the Clock Tower!


Basically, the world's theme is a floating city in the sky.
