Mushroomy Kingdom is basically a distorted copy of World 1-1 of Super Mario Bros. All item boxes will grant the player a random item (based on witch ones are turned on) and all the other boxes can be broken with any attack. The background of this stage is very much a desert and not too friendly looking. This stage scrolls to the left on its own and once the end of the level is reached it goes back to the start of it. Note that all the boxes are back to the original state. This stage also has a chance of being World 1-2, which acts just like World 1-1 just this time a different level.
