The level starts out with the setting from the beginning of World 1-1 from Super Mario Bros., except with enemies and a beanstalk inside of the ? Blocks. A few warp pipes appear with a wall of synchronized Fire Bars. Mario must enter the warp pipe, and he will end up in the same beginning as before, except with bigger enemies. As Mario jumps across each warp pipe, he will encounter a Blooper on top of two Hammer Bros., a synchronized row of Fire Bars that Mario must avoid by climbing the beanstalks, and a segment where Mario must jump onto each conveyor belt and Koopa Paratroopa while avoiding Grinders to reach another warp pipe. Mario will then end up in a Lakitu cloud and must ride down to the Goal Pole.
