World 1-2 (New Super Mario Bros.)

In New Super Mario Bros., World 1-2 is a cave level similar to World 1-2 from Super Mario Bros.. At the beginning of the level, Mario will fall down a hole into a cave. Three Brick Blocks which are on top of nine coins will then appear. Mario should then go down a short rocky stairway and up another. After this, he will find a few ? Blocks and brick blocks covering coins. Immediately after this, Mario can Ground Pound through numerous blocks to go further underground and find a large number of coins. In order to leave this area, Mario can either wall jump through the shaft he came through or jump up using a spring. The first Star Coin in the level is right the spring. It can be reached by jumping on top of some blocks and going into the rock alcove. Just past this, the first Koopa Troopa in the level will appear. Also, by jumping on top of some brick blocks in this area, breaking some on top of him, and wall jumping of the wall, Mario can walk on top of the brick blocks on the top of the level. Although this way is one way to get past the wall of brick blocks in this area, the main way is simply breaking them. Right after this, Mario can obtain the second star coin by breaking the blocks surrounding it. After that, there is a log which will tip back and forth based on where Mario is walking. Right after the Midway Point, Piranha Plants will appear for the first time in the entire game. After the Piranha Plants, there are two Warp Pipes which Mario can jump on to proceed, and several enemies. Then there is another log. Mario can use this log to get to the secret exit, which will allow him access to the Toad House. The final star coin can only be found this way. If Mario chooses not to do this, then he will come across several brick blocks, a pit, and the warp pipe which lets him leave the cave. Mario will then go through the pipe and surface in an area similar to World 1-1. He will then slide down the flagpole and exit the level. The secret exit is the same, except the stairs to let Mario slide down the flagpole are floating in the air and the flag is red instead of black.
