'''World 1-2''' is the second level of [[World 1 (New Super Mario Bros.)|World 1]], and subsequently, of ''[[New Super Mario Bros.]]'' Completing this level through the normal exit will unlock [[World 1-3 (New Super Mario Bros.)|World 1-3]], whilst exiting the level from the secret exit will give the player access to {{world-link|1|towern|World 1-Tower (New Super Mario Bros.)}}.
==Layout==
The level begins with [[Mario]] [[Ground Pound]]ing into the cave, breaking a few [[Brick Blocks]] directly below him and collecting some [[coin]]s. Right after this are two [[? Block]]s, one of which contains either a [[Super Mushroom]] or a [[Fire Flower]], depending on Mario's current form. There are also additional coins that can be collected with more Ground Pounding. Just after this, a [[Goomba]] appears, the first of many throughout the level. The first [[Star Coin]] can also be located nearby in an alcove.

After this are more enemies, including [[Koopa Troopa]]s, as well as coins. There is a long row of Brick Blocks overhead, one of which contains a [[1-Up Mushroom]]. The second Star Coin appears just after this, surrounded with blocks that can be broken either by Ground Pounding or with a Koopa Troopa's shell. After a [[seesaw]] is the level's [[Checkpoint Flag]].

Up next are [[Piranha Plant]]s in [[Warp Pipe|pipe]]s. A [[Hidden Block]] containing a [[Super Star]] can be found in this area. The first pipe can also be entered to find a secret area with a few extra coins, as well as a red Koopa Troopa whose shell can be used to clear away a row of Brick Blocks below, revealing another hidden area filled with Goombas, as well as a ? Block containing a [[Mega Mushroom]].

Back in the main area, Mario must traverse a few more obstacles in the level, including enemies and a seesaw, before entering a Warp Pipe to return to the surface, where the [[Goal Pole]] allows him to finish the level. Alternatively, in a nod to [[World 1-2 (Super Mario Bros.)|World 1-2]] from the original ''[[Super Mario Bros.]]'', Mario can continue upward and to the right to find the level's third and final Star Coin and a pipe leading to [[Goal Pole (secret)|a secret Goal Pole]].

==Red-flag exit==
Towards the end of the level, there will be a small gap at the top of the screen like [[World 1-2 (Super Mario Bros.)|World 1-2]] in the original ''[[Super Mario Bros.]]'' that Mario can access using the seesaw. Running across the gap will lead to the third Star Coin and a pipe, which will lead to the [[Goal Pole (secret)|red-flag exit]]. Using the red-flag exit unlocks a different path that directly leads to a secret [[Toad House]] and the tower of that world.

==Star Coins==
*'''Star Coin 1''' - In the beginning of the level, it can be found on a ledge that needs the use of bricks to get it.
*'''Star Coin 2''' - A huge plethora of blocks surrounds this coin. Ground pounding the top of the box will reveal an opening.
*'''Star Coin 3''' - On the way to the secret exit, the Star Coin should be in plain sight.
