World D

Template:Worldbox World D is the fifth and final secret world and the thirteenth and final world that was featured in the game Super Mario Bros.: The Lost Levels. Like the other secret worlds, it was left unused in Super Mario Bros. Deluxe. When Bowser is defeated at the end of World D-4, Princess Toadstool is saved, and, as such, Mario and Luigi beat the game.

Level information

Level	Preview	Description
World D-1	File:World D-1.PNG	A level similar to World 8-1. In the original FCD version, it is a snowy level, but in the SNES remake, its a grassy level.
World D-2	File:World D-2.PNG	This level includes several upside down Piranha Plants.
World D-3	File:World D-3.PNG	A level which has a brick wall in the background similar to World 8-3's. In Super Mario All-Stars the wall is gone so the brick blocks are replaced with hidden blocks.
