World 2 (New Super Mario Bros. 2)

World 2 is the desert world of New Super Mario Bros. 2. This world introduces the new Gold Flower power-up, where Mario can transform into Gold Mario (and Luigi to Silver Luigi). This world has 4 Toad Houses, two are red, one is green and the last is a Star Toad House. It is also the first world with a Ghost House in the game.

This world consists of 10 levels. 8 of them are on the main path and 2 levels are optional. This world is also optional as it can be bypassed by completing World Mushroom. The map music and overworld music of the world is similar to that of World 2 of New Super Mario Bros. Wii. The world layout is also similar to World 2 of New Super Mario Bros.. The boss of this world is Iggy Koopa.

First, Mario will come across some tilting Brick Blocks, one of them is a ? Block containing a Fire Flower, followed by a Piranha Plant. Throughout the level, there are tilting Brick Blocks which acts as platforms, and Piranha Plants being the main enemies. There is also a Red Ring which will make 8 Red Coins parachute into the level. After the checkpoint, there are also Note Blocks, Koopa Troopas and Koopa Paratroopas. The Gold Flower is also introduced in this level (see Star Coin 2). After the last Piranha Plant, several tilting Brick Block platforms can help Mario reach the top of the flagpole.

Star Coins
The three Star Coins in this level are located very close to each other.


 * Star Coin 1: Before the checkpoint, there is a gap on the ceiling. Attempting to pass through the gap will make a hidden block containing a coin appear. Mario needs to go to the left of the gap and jump towards the right at the topmost point. He should land on a platform. The Star Coin should be in sight now
 * Star Coin 2: After the checkpoint, there is a gold Warp Pipe. Warping through will take the player underground. The player can find a Gold Flower in a lone ? Block, which allows Mario to shoot fireballs that change Brick Blocks into coins, activate them, or score coins instead of points when killing enemies. When Mario sees the first Goomba, he should stop shooting fireballs (just in case). Mario can then use the Brick Blocks as platforms to reach a ledge where the Star Coin is. He can obtain it by shooting the obstructing Brick Blocks with fireballs. In any case the Brick Blocks were changed into coins, the player can still use the Goomba Tower nearby (if still intact) to leap up to the ledge.
 * Star Coin 3: This Star Coin is located just before the last set of Note Blocks. (If the player just obtained the second Star Coin, he needs to go towards the left.) The player needs to use the Note Block to reach a high tilting Brick Blocks while avoiding the Paratroopas to obtain the last Star Coin.

The player is on a moving platform. Towards the end are many Fireballs jumping out of the lava. At the end the player battles Iggy Koopa. His battle is like his battle in New Super Mario Bros. Wii. A Chain Chomp pulls him. The player will have to stomp on Iggy 3 times.
