Super Mario World

Super Mario World is a 1-P stage appearing as the first level of the Adventure mode in Super Smash Flash. As the name implies, it is the ripped level Yoshi's Island 2 from the game . However, the stage itself is not an exact replica of the level as many elements from the original game are missing in the SSF version, ex: Flying Goombas are not found in this level.

Layout
The stage possesses platforms from Yoshi's Island 2, although not all are present. Near the beginning is a plateau with some red Koopa Troopas walking on it as well as some used blocks the players can stand on. After passing a long way with more Koopas and encountering the first Flying Goombas, the player finds some Warp Pipes followed by three plateaus to stand on. Above the first of the plateaus there is a platform made of many Lakitu clouds which can be reached only by doing a second jump with the help of some Flip Blocks, a Flying Goomba is also found in there. Following the way, the next plateau is found, though it is a bit smaller than the previous found. Finally, more Koopas, Warp Pipes, and square-shaped Flip-Blocks are found and the Giant Gate to complete the level.

Enemies

 * Koopa Troopa
 * Flying Goomba

Origin
As previously mentioned, the sprites for this stage were ripped from those of Yoshi's Island 2, the second level of Super Mario World and the first level where completion is required to beat the game. Thus, the main layout of the level and most of its set pieces are identical as well, but the alignment of its enemies are different; most notably, Flying Goombas do not appear. Like in all levels of the game, the player must pass the Giant Gate to complete it. This level in particular is notable for how Yoshi makes his very first appearance in the  series as a rideable companion, though this is absent as well.
