World Flower (New Super Mario Bros. 2)

World  is the second special world in New Super Mario Bros. 2. As in World Mushroom, this world has a generic design, having a background colour of green. This is an optional world to completing the first goal of the game (that is, beating Bowser) and serves as an alternative world to World 4. This world can be accessed by completing either World 3-Cannon or World Mushroom-Cannon.

There are a total of nine levels and three Toad Houses in this world. There are three normal levels, a Ghost House and a Castle on the main path, and an additional two levels and a Cannon which can be found by secret exits in the other levels. The three Toad Houses includes two that are green and one which is red. The boss of this world is Lemmy Koopa, fought at the castle at the end of the world. Defeating him will take the player to World 5. The cannon in this world takes the player immediately to World 6, thus skipping World 5 as well. Note that a player can skip almost all normal worlds in the game (except World 1 and World 6) by taking the cannon of every entered world until the battle with Bowser (World 1-Cannon, World Mushroom-Cannon and World Flower-Cannon).

To access this level, the timer must end with the two digits '88' (that is, 'x88', where 'x' can be any number) when the player reaches the flagpole of any World Flower level. Once the level is completed, it can be accessed again by satisfying the above condition once more.

The level begins with Mario beside the Cannon Pipe in the generic world. Upon entering the pipe, two, columns of coins will appear and Mario will be shot to the sky, collecting the coins. Mario will land on a rainbow-coloured platform. First, sets spinning coins arranged in the shape of a fan can first be found. Some coins will then jump up from the abyss below. A Red Ring can then be found, where 8 parachuting red coins will then appear. During this time, a 100 Gold Coin will fall. Finally, more spinning coins can be found before Mario jumps down and the level ends.

This level takes place in the mountains during sunset, and the floor is mainly made up of pipes, mainly infested with Piranha Plants. Mario begins partially enclosed in a set of Snake Blocks on a blue pipe. Above is a set of three ? Blocks, of which one contains a Super Leaf. Mario will then have to jump from Snake Block to Snake Block to leap over an abyss. More Snake Blocks can be found next, also leaping over an abyss, then a Goomba can be found. An area with fast Snake Blocks follow, where Mario have to walk on the Snake Blocks quickly to the other side. The checkpoint can then be found, followed by ? Blocks which one of them has a Super Leaf. Mario will then come across an area with many Snake Blocks where he needs to make his way upwards to the other side. Two ? Blocks can be found above a single Koopa Troopa. The one on the right will begin flying when hit and hitting it again releases a 1-Up Mushroom. Mario then has to cross several gaps in between mini pipes with Snake Blocks above them. After that several Goombas can be found on more Snake Blocks, followed by the flagpole.

Star Coins

 * Star Coin 1: The first Star Coin can be found early in the level between two sets of Snake Blocks guarded by a Paratroopa. Mario will have to drop down to the lower half of the mini pipe on the left and slowly use the Snake Blocks to reach the Star Coin.
 * Star Coin 2: The Star Coin is just before the checkpoint beside a mini pipe. Mario needs to wall jump off the nearby Snake Blocks when it gets close enough to reach the Star Coin.
 * Star Coin 3: At the top of the area where Mario needs to make his way upwards after the checkpoint, there are two blue pipes on the left and a yellow one on the right. Mario should carefully slide down the side of one of these pipes to find the Star Coin and wall kick back up afterwards.

Secret Exit
When Mario reaches the two ? Blocks before the area with the Snake Blocks above the mini pipes, Mario needs to hit the right ? Block to make it fly, then stand on top of the block until it flies upwards, taking Mario to a hidden area in the sky. This is best achieved by performing a ground pound on top of the block while it is not flying. Mario then has to cross several sets of Snake Blocks, which ends with the flagpole.

This exit unlocks World Flower-A.

To unlock this level, the player has to locate the secret exit in World Flower-1.

This level takes place underground, in an icy area. Mario begins on a non-slippery platform above the ice. A Koopa Troopa can then be found on the ice, below two ? Blocks and a Brick Block, one of then containing a Super Leaf. Jumping over several small gaps, Mario will meet several Buzzy Beetles on the ceiling. Mario will then travel to the other side of a large abyss on an ice platform. Several Buzzy Beetles and Koopa Troopas will fall from smaller ice platforms during the ride. Spike Tops will then begin to appear. At the end of the ride is the checkpoint. Another Super Leaf can be found in a ? Block after that. Mario then has to jump across several gaps from platform to platform which have Spike Tops and Buzzy Beetles on them. In between the gaps are rectangular Ice Donut Lifts. Furthur on, Mario will have to make his way downwards to several one-way gates and drop down to and ride on another moving ice platform. Koopa Troopas, Buzzy Beetles and Spike Tops can be found along the ride. Several rectangular Ice Donut Lifts are also in place during the ride. At some points, Mario will have to either duck or jump over some platforms. Mario will then have to jump off the moving ice platform onto a platform below the exit Warp Pipe at the end of the ride as it continues moving off the screen. Back outside, Mario will need to ride another moving ice platform to get across an abyss. A single square ice platform can be found during the ride before Mario reaches the flagpole.

Completing this level will unlock World Flower-Cannon and a green Toad House.

Star Coins

 * Star Coin 1: The Star Coin can be spotted above an ice platform which is used by the first Spike Top to walk on.
 * Star Coin 2: The second Star Coin is below the third ice platform after the checkpoint. Mario will have to grab a nearby Buzzy Beetle and aim and toss it from the left to a Brick Block under the next platform so that the shell will bounce off the platform walls at the right positions into the Star Coin.
 * Star Coin 3: This Star Coin can be found above the second square ice platform being used by two Spike Tops during the second ride.

To unlock this level, the player needs to complete World Flower-A.

The level begins with Mario beside the cannon in the generic world. Entering the cannon begins a countdown, and then Mario is blasted off into the course. In this level, Mario needs to navigate through a rather difficult course of parachuting Bomb-ombs and rotating and stationary electric Amps, while preventing falling down the large abyss. A single Red Ring can be found halfway through the course which causes 8 red coins to appear that Mario can collect to earn a power-up. After that, the level ends. This level can be made significantly easier if Mario was in Raccoon Mario form before starting the level.

Completing this level will unlock World 6-1.

Mario begins on the floor of the ghost house in front of a Boo and under a spider web. Going up are two sets of ? Blocks and Brick Blocks on each side of the wall. One of them is a multi-coin Brick Block and another contains a Super Leaf. Mario then has to climb up more spider webs to the next level, where even more spider webs, a Boo and a Gold Ring awaits. Obtaining the Gold Ring will cause the Boo to turn golden, move away from Mario and leave behind a trial of coins. The path up then splits into two. Up the left path are several sets of stairs with several Goombas on them. At the next level is a Big Boo, more spider webs and another Gold Ring. Climbing up the spider webs leads to the top level where a lone ? Block sits above the second Star Coin. The ? Block contains a Star which, upon collecting, turns all floors, stairs and spider webs into coins and the room changes significantly, such as the lowest level now being filled with water. Mario will then have to move to the right (at the bottom of the Ghost House) into a small path. Boohemoth then appears. Mario will have to navigate through the path which is halfway filled with water. Strong water currents can be found here along with several Peepas. A door leading outside can then be found. A Boo and several more spider webs can be found, followed by the flagpole.

Star Coins

 * Star Coin 1: At the fork, the player should take the right path and navigate through the spider webs to find the Star Coin.
 * Star Coin 2: This Star Coin can be found enclosed in walls below a ? Block containing a Star. Mario will need to collect the Star within the area above the Star Coin so that Mario will drop down to the Star Coin when everthing changes to coins.
 * Star Coin 3: Before the door leading to the flagpole, the Star Coin can be found under a set of stairs. Mario will have to navigate through the water under the stairs to reach the Star Coin before Boohemoth blocks it.

Secret Exit
Upon obtaining the Star at the top of the first area, Mario will need to slide down the right wall to land on a hidden platform. Going right leads to the next area, where a door can be found. Going beyond the door to the right leads to a hidden area with coins and a Brick Block containing a 1-Up Mushroom. The door leads outside, where Mario will fall and land on the ground. Outside, a Big Boo can be found. Mario then has to climb several spider webs to get past a large abyss to the other side, avoiding Boos, where the flagpole can then be found.

This exit unlocks World Flower-B.

The level begins with Mario on an elevated platform beside a vine whichwill be constantly swinging at the start of the level. Mario needs to swing on the vine to cross over to the other side and then drop off the cliff to the ground. Before the cliff a ? Block can be found containing a Fire Flower. On the other side of the cliff a hidden block containing a Star can be found directly above a multi-coin Brick Block. Moving forward, Mario will then to cross a gap, then a red Koopa Paratroopa and a red Koopa Troopa can be found on another orange elevated platform.

On the other side, a multi-coin Brick Block can be found with a red Koopa. Mario will then need to swing on another vine to reach another set of rotating platforms to cross the toxic water. More elevated platforms can then be found, followed by a Koopa and a Scuttle Bug. On the other side, a Koopa can be found, followed by another vine with a Red Ring in the middle. A Paratroopa can be found, then Mario will have to climb up a ledge and get to the other side, where a Koopa can be found which can be used to release a P-Switch from a Brick Block. Activating the P-Switch causes blue coins to appear. Mario will then have to cross a large gap of toxic water by swinging from vine to vine, and then bouncing from Scuttle Bug to Scuttle Bug to reach a green Warp Pipe. Warping through takes Mario to the last area, where two Scuttle Bugs can be found, followed by a high vine which can help Mario reach the top of the flagpole right after.
