The stage is made up of three sections. There are two upper platforms on either side of the stage and one lower platform in the middle. The center platform is actually two 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 Melee version.
The music track is an incomplete rendition of Princess Peach's Castle, an orchestral remix of the ground and underground themes from Super Mario Bros., ripped straight from Super Smash Bros. Melee.
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 does not show up at the end of every area to shoot eggs at the player, Pidgit and his flying carpet are also absent.
This stage is rather infamous due to its appearance as the second level of Classic mode, where the player must face Mario and Luigi (but only if he has been unlocked) with Samus as the teammate, as most of the time the match ends early due to Mario and Samus self-destructing in the gaps of the stage.
The track that plays on this stage did not originally play on the original version in Super Smash Bros. Melee instead of the original ground theme from Super Mario Bros. 2 as the main music track.
