Mushroom Kingdom II (Super Smash Flash 2)

Mushroom Kingdom II is a starter stage in Super Smash Flash 2 that originally appeared in  as an unlockable stage. Mushroom Kingdom II was originally added in demo v0.5b, though it was removed in demo v0.8a in favour of the brand new Mushroom Kingdom III. For SSF2 Beta Dev Blog #8, it was confirmed that Mushroom Kingdom II was returning for Beta, sporting an updated design.

Layout
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 's Vegetable move, which would have been buried in the ground as soon as the match starts.

Music

 * The main music track is Overworld (Super Mario Bros. 2), an upbeat piano remix of the ground theme from Super Mario Bros. 2.
 * The alternate music track is Caves (Super Mario Bros. 2), a funky remix of the underground theme from Super Mario Bros. 2.

Tournament legality
This stage is banned in competitive play. It has walk-offs on both sides and two pits that make certain recoveries like ' difficult or impossible.

Origin
This stage is from Super Mario Bros. 2, but the graphics of the background of the stage are from the  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. Like in Super Smash Bros. Melee and Super Smash Bros. Ultimate, Birdo comes from either side of the stage and shoot three eggs at the players in SSF2. 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.

Trivia

 * Mushroom Kingdom II, Waiting Room, and Yoshi's Island (64) are the only stages to be cut from an earlier version of the SSF2 Demo, only to be brought back in Beta 1.0.
