Mushroom Kingdom II (Super Smash Flash)

Mushroom Kingdom II, also known as Subcon, is a Mario stage featured in Super Smash Flash as the second stage representation from said series. It is based on the stage of the same name from Super Smash Bros. Melee. The stage is rather unfamous due is appearance as the second level of the Classic Mode where the player must face and  (but only if he has been unlocked) with  as the teammate, with most of the time the match ends early due to Mario and Samus self-destructing in the gaps of the stage.

Layout
The stage is made up of 3 sections. There are two upper platforms on either side of the stage and one lower platform in the middle. The center platform is actually 2 platforms connected by a log. There is a pit on either side of the middle platform. There were no logs fall in the waterfall, unlike in the Meleeversion.

Music
Oddly in SSF, this stage's BGM is Princess Peach's Castle as opposed to the original Super Mario Bros. 2: Ground Theme from Melee. Because of that, the music also loops earlier than usual.

Origin
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. Unlike in Melee, Birdo doesn't show up at the end of every area to shoot eggs at the player, Pidgit and his flying carpet are also absent.
