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 mostly underground. After passing a few floating platforms and some Pokeys, the player encounters a few rotating pinwheels consisting of three platforms, one of which will contain a Pokey on it. After passing that section the player will find the checkway point, a spring, A Roulette Block and a block that acts like a Roulette Block except with coins. In order to hit any of the blocks the player will have to pick up the spring and drop it under the block they want to hit and bounce on the spring. There will be Spike Tops walking around the border of the blocks. After passing the checkpoint the player will soon enter a yellow pipe. (see Star Coin 1) After a while they will encounter a few floating platforms, 2 of which have Pokeys on them. There's also a Red Ring in the middle of all of the platforms. (see Star Coin 3) After passing a few Buzzy Beetles, the player will enter a yellow pipe that'll blast them out of the underground. Once they are back on the surface the flagpole shouldn't be far.

Star Coins

 * Star Coin 1: Instead of entering the first yellow pipe, the player should jump on the Buzzy Beetle that is on it, go to the bottom floating platform, and throw the shell at the Red POW Block. Enter the yellow pipe that the player just gained access to. After they enter the pipe, 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 From the pipe that got the player out of the area containing the 1st star coin, jump on the Buzzy Beetle and pick it up, keep on going left until the player finds find a small pit between a few brick blocks. Throw the Buzzy Beetle shell into the indent, it should trigger a chain reaction of multiple brick blocks breaking. Enter the new passage the player made and keep on going, they will eventually find the Star Coin, along with a pipe that keeps on creating Goombas.
 * Star Coin 3 Instead of going straight forward to the the final pipe, try to get as far to the top of the floating platforms as the player can and attempt to land on the floating group of blocks. Avoid all of the Spike Tops and navigate through the series of block platforms, the final star coin should just be a hop away from the final block platform.

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.
