Mushroom Central

Mushroom Central is the main world of the Mushroom Kingdom. It is the first world of Bowser's Revenge. The world has thirteen levels.

1-1, False Start
World 1-1, False Start describes a dream that Mario has of defeating Bowser. The level starts in a grass section, and has three paths that can be taken to get to the castle section. There is an underground path, a sky path and a water path, which all lead to a castle and a fight against Bowser. The level is short, but hard, and can be skipped on the world map. The pipe at the beginning of the castle section takes the player back to the grass section, where they can take the other paths. There are three star coins in this level. At the end of the level, two Subcons tell Mario it was all a dream, and send him back to the Mushroom Kingdom.
