The Mushroom Kingdom is the first world in Mushroom Kingdom Fusion. It is Mario, Luigi, and Wario's home world. Bowser is the World Boss. The majority of the levels in the Mushroom Kingdom are original levels, done in a classic Mario style similar to either Super Mario Bros. 3 or New Super Mario Bros., although there are a handful of levels scattered throughout that are modeled directly after specific levels throughout the Mario series. This world is divided up onto 8 "lands", areas with levels based on a specific environmental theme. Each "land" has it's own seperate screen on the map, except the last one, which takes up two.
The Mushroom Kingdom also counts as the game's "hub" world; not only does the player start here, but they also must return here after completing each other world in order to open up the route to the next. After returning to World 1 after completing a different world, the game will indicate a specific level that has started undergoing the Fusion effect while the player was away. These levels contain "World Exits", special secret routes containing a mini-Fusion level related to the world it connects to. By completing a World Exit, the player will gain permanent access to the warp pipe leading to that particular world.
