World 1-2 (Super Mario Bros. Special)

World 1-2 is the second level of World 1 from Super Mario Bros. Special.

Layout
The level starts off with Mario entering a pipe, which leads him into an underground section. Here, there is a Brick Block roof over a Hard Block staircase. Past this staircase is a set of five ? Blocks, leftmost containing a Magic Mushroom or Fire Flower, over two Little Goombas. After these is a Hard Block structure, which slightly hints towards a secret Magic Mushroom or Fire Flower Brick Block over the highest Hard Block. Following this are two green Koopa Troopas under a Brick Block structure in an "L" shape with a few coins on it. Past this is a pit followed by another Brick Block structure, this one containing a Magic Mushroom or Fire Flower on its end. After this is a rectangle made of Brick Blocks which coins on top of it and three Little Goombas. This is followed by a set of four ? Blocks, all containing coins, and another Brick Block structure with two Little Goombas under it. This Brick Block structure has three holes, two blocked off from below and above, each containing a single coin. Over the left hole is a hidden 1 up Mushroom in a Brick Block, and under the right hole is a Starman hidden in a Brick Block. Past this is a lift generator, with each lift going downward. After this is a Warp Pipe, which can be entered. Upon entrance of the Warp Pipe, the player will find themselves in a room filled with coins and Brick Blocks, which then leads to three upside-down Warp Pipes, each with Hidden Blocks in between them. To the right is a sideways Warp Pipe, which leads to an overworld section. The player will meet a set of four ? Blocks, followed by a pit and a Hard Block structure with two Little Goombas on it. In the middle of this Hard Block structure is a ? Block containing a Magic Mushroom or Fire Flower. After this is a group of a green and red Koopa Troopa, along with a Little Goombas stuck between two Hard Blocks. Past this is the flagpole area. If the player were to ignore the initial secret pipe, they'd continue onto a set of two ? Blocks, leftmost containing a Magic Mushroom or Fire Flower, and four Warp Pipes. After a set of three ? Blocks, the player finds the ending Warp Pipe, which leads to an overworld section connected to the secret overworld section (though the player cannot scroll back to the secret area). Upon climbing the Hard Block staircase, Mario finds the ending flagpole.
