'''World 9-1''' is the first level of [[World 9 (Super Mario Bros.: The Lost Levels)|World 9]] in ''[[Super Mario Bros.: The Lost Levels]]'' and the first secret level overall in said game. It is primarily underwater, but uses graphics typically associated with overworld levels; because of this and the palette assigned to underwater levels in the original, many pipes and bushes appear with the pink coral's palette, and [[Bill Blaster]]s are tinted the same green as the terrain. However, in ''[[Super Mario All-Stars]]'', the palette oddities are fixed.

In ''[[Nintendo World Championships: NES Edition]]'', completing this course as [[Mario]] is the goal of a Master-difficulty challenge titled Divemaster.

==Layout==
The player starts in a small area looking similar to the [[Warp Zone]]s in earlier levels with a [[Warp Pipe]] with a [[Piranha Plant]] in it that leads to the underwater portion of the level. This is also the only playable level in the game to have the player enter the underwater portion willingly, as opposed to the player character automatically entering a Warp Pipe to enter the underwater or underground portion of the level.

The player is dropped into the water above a pipe with a Piranha Plant, followed by a [[Koopa Paratroopa]]. On top of a row of [[? Block]]s is a Bill Blaster, however it cannot fire any [[Bullet Bill]]s underwater. After some downward moving [[lift]]s above a current is another Koopa Paratroopa, followed by an alternating from the top and bottom group of pipes with Piranha Plants the player needs to swim through. After some more Koopa Paratroopas, the player will come across [[Lakitu]], followed by a group of [[Koopa Troopa]]s, [[Goomba]]s, and more nullified Bill Blasters before coming to a [[Hammer Bro]]. After some [[Blooper]]s, [[Buzzy Beetle]]s, and more Koopa Paratroopas is the [[Goal Pole]].
