World Flower (New Super Mario Bros. 2)

World Flower 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.

This level starts with Mario shooting out of a Cannon Pipe and collecting Coins while being shot into the sky. This level has coins circling around in groups of seven. There is also a Red Ring in this level, which gives the player a Gold Flower if all of the Red Coins are collected. During Mario's red coin collecting, a 100 Gold Coin will appear. This will give the player 100 coins, resulting in an extra life. The level ends when the player falls back down to the World Map.

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.

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.
