The stage was rather similar to its SSF counterpart in terms of layout. Some hazards are included in this incarnation such as Birdo, who makes brief appearances in both sides of the foregrounds to hurt combatants by shooting eggs at them. A Pidgit also descends on its carpet. This carpet works as an extra platform. A gimmick that was planned, but never implemented was the ability to pick turnips, similar to Peach's Vegetable move, which would have been buried in the ground as soon as the match starts.
The main music track is titled Overworld (Super Mario Bros. 2), an arrangement from the aforementioned game.
The alternate music track is titled Caves (Super Mario Bros. 2), another arrangement from Super Mario Bros. 2.
This stage is banned in competitive play. It has walk-offs on both sides and two pits that make certain recoveries like Ness' difficult or impossible.
This stage is from Super Mario Bros. 2, but the graphics of the background of the stage are from the Super Mario All-Stars version of Super Mario Bros. 2. In Super Mario Bros. 2, a Birdo usually serves as a mini-boss at the end of each area. Birdo will shoot eggs at the player. From the SSF2 version of the game, Birdo comes from either side of the stage and shoot three eggs at the players. In Super Mario Bros. 2, characters have to jump on a Pidgit and take its carpet to proceed through a level. For SSF2, characters have the ability to jump and stand on Pidgit's carpet.
