Subspace[1] (alternatively Sub-space[2][3] or Sub-Space[4]), also known as the Hidden World[5], is an alternate dimension to Subcon in Super Mario Bros. 2. In Subspace, everything is turned dark and reverses direction on a single screen which the player cannot travel beyond. Subspace can only be accessed by use of the Magical Potions (which create doors leading to the land) in Super Mario Bros. 2.

When Mario or his friends enter Subspace, they only have a few seconds to get the Mushroom that may or may not appear; it depends on where in Subspace the hero has entered. In Subspace, all items found in the red grass are transformed into coins when the player plucks them, giving the heroes an chance of earning extra lives in the slot machine Bonus Chance at the level end. Depending on the area, players can also collect cherries, Starmen, and POW.

A few jars allow the player to skip to another world like a Warp Zone.

There are no enemies, but Phanto can follow the player into Subspace if he or she was holding the key. The player can still die by falling into a pit or drowning in quicksand. In both remakes, the background is the same, but the level actually has color and is not just simply black. Additionally, in the GBA remake, Yoshi Eggs could be found here after Wart is defeated.
