World 1-2 (New Super Mario Bros. 2)

The level starts off with a green Warp Pipe. Above it is a green Koopa enclosed in Brick Blocks, and the first red POW Block. Hitting the block will destroy the Brick Blocks and overturn the Koopa. The POW Block itself turns into a Used Block. Going down the pipe, the player will automatically ground pound and hit another red POW Block. The level is full of Koopa Troopas and red POW Blocks, which breaks empty Brick Blocks, triggers those containing items or reveal hidden items. Mario will then come across several Brick Blocks where the player can see three Koopas and two POW Blocks (see Star Coin 1). A gold Warp Pipe follows (see Star Coin 2). A Piranha Plant can be seen in the next gold pipe. Moving platforms appear. After that, the player can see the first pipe which turns fireballs into coins. To access it the player needs to use a Koopa to activate a POW Block. Exhausting the pipe will release a Mega Mushroom. After several more Koopas and Piranhas the player reaches the checkpoint flag. Mega Mario is needed to break several blocks to obtain another Star Coin between two sets of moving platforms. After that, a pipe leads back to the overworld, where another set of Brick Blocks can be found with a POW Block, followed by the flagpole.

Star Coins

 * Star Coin 1: The first Star Coin is hidden in several Brick Blocks where the player can see three Koopas and two POW Blocks. To obtain it, the player has to activate the POW Blocks by using the red Koopa on top, revealing the Star Coin.
 * Star Coin 2: The player needs to go down the first gold Warp Pipe he comes across. The player then has to hit the P-Switch and dash to the Star Coin while avoiding the Koopas before the timer runs out.
 * Star Coin 3: After the second Star Coin, the player will come across a black Warp Pipe. Mario/Luigi will need to spit fireballs into the pipe. Eventually, a Mega Mushroom will come out. The player should grab it and run to the right, because Mega Mario is required to break the blocks surrounding the Star Coin.
