World 1-2 is the second level of World 1 in Super Mario Bros.: The Lost Levels.
Layout[]
This is the first underground level of the game. There is a small cut scene at the beginning of the level showing Mario or Luigi walking into a pipe in the overworld. In this level, there are Goombas, Piranha Plants, and Koopa Troopas the player has to avoid, and a large canyon where the player must quickly jump over the platforms to cross. Now the player has to cross pipes infested with Piranha Plants, and some Koopa Troopas. Here, the player can either go to World 1-3, go up a vine to the World 3-1 Warp Zone, go above the exit to 1-3 to a World 4-1 Warp Zone down the first pipe, or continue on to a World 2-1 Warp Zone. When going down the pipe to the World 4-1 Warp Zone, if the player loses a life, he or she will start at the beginning of the level instead of at the midway point.
