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.

This aerial level takes place on tikis that have wing-like structures, acting as platforms throughout the level. Mario starts in between two ? Blocks, the latter containing a Fire Flower. This is followed by a Paragoomba and several Brick Blocks. Red Koopa Troopas follow. A Gold Ring appears in between two ? Blocks on the ground under a Koopa which allows Mario to earn extra coins with the Koopa. A Hammer Bro. can then be found (see Star Coin 1). Yellow platforms which tilts with respect to weight follows, where Mario must be careful or else he could fall. After that is the checkpoint, where another Fire Flower can be found. Another tilting platform can be found above another Hammer Bro.. This is followed by a Red Ring. After crossing several gaps, a Boomerang Bro. can be found to the right of several Brick Blocks. On the next platform is another Hammer Bro. on Brick Blocks. At this point Mario needs to travel upwards. Going upwards to the first level the player will encounter a Boomerang Bro. and a Koopa Troopa. To the right of that platform is another platform with a Coin Roulette Block. Going up the next level to the top floor is a Sledge Bro. between a Brick Block (which can be turned into a Gold Block) and a ? Block with a Fire Flower. Going right is the last platform with several tiki heads which can help Mario reach the top of the flagpole.

Star Coins

 * Star Coin 1: The first Star Coin is located above the first Hammer Bro..
 * Star Coin 2: On the platform right after the platform with the Red Ring, Mario can find a gap between the two smaller platforms. Dropping down leads to a gold Warp Pipe, taking the player to an area with two Boomerang Bros. and the Star Coin, along with several coins.
 * Star Coin 3: In the last part, when Mario encounters the Sledge Bro., he should go towards the left and jump the gap to a smaller platform. He will meet a Paragoomba which Mario has to jump on to reach the Star Coin.

This level takes place underground. The player starts on the desert ground where a Pokey can be found. Entering the gold Warp Pipe takes the player underground. The main power up, the Super Leaf can be found in a ? Block above the first Pokey underground. After passing a few floating platforms and some Pokeys, the player will encounter a few sets of rotating platforms with several Pokeys on some of them. The player will then find the checkpoint, a Roulette Block, two Coin Roulette Blocks (each Roulette Block has two Spike Tops) and a springboard used to bounce to the Roulette Blocks high up. After passing the checkpoint, there are two platforms moving up and down with a Pokey and a gold Warp Pipe which warps the player to the next area. There are Brick Blocks, ? Blocks and red POW Blocks in this area (see Star Coin 2), followed by platforms that go in opposite directions (two sets move downwards and one set moves upwards), two of which have Pokeys on them, and a Red Ring. After passing a few more Buzzy Beetles and crossing quicksand, a green pipe can be found to blast Mario out of the cave. Back on the surface, there are several stone platforms with Pokeys floating over a pool of quicksand. Crossing it leads to the flagpole.

Star Coins

 * Star Coin 1: Just after the checkpoint, the player should see two Warp Pipes, the lower one obstructed by Brick Blocks. A Buzzy Beetle can be found on the upper pipe. The player has to pick up the Buzzy Beetle and go to the lower moving platform (the one without the Pokey) and try to activate the outer POW Block. If successful, a path will open for the player to reach and enter the pipe. After entering the room, the player should go left and drop down the hole. There are many Piranha Plants that pop out simultaneously every few seconds. Grab the Star Coin that's on the player's left and head back right.
 * Star Coin 2: At the beginning the second area, there is a gap in between the Brick Blocks. The player needs to carry the Buzzy Beetle found further down the level to just before the gap. Releasing the shell will activate all the red POW Blocks, opening a path to the Star Coin. The player should also watch out for the Goombas.
 * Star Coin 3: When reaching the Red Ring, the player needs to climb up the third set of downward moving platforms while moving towards the right to a platform made of Brick Blocks and POW Blocks. Navigating through the path by jumping from platform to platform will bring the player to the 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.
