World Flower (New Super Mario Bros. 2)

World Flower is the second special world in New Super Mario Bros. 2. This world has a generic design which is similar to that of World Mushroom and World Star. The background colour of this world is green. It is an alternative world to World 4 and thus it is optional. This world can be accessed by completing either World 3-Cannon or World Mushroom-Cannon. There are three Toad Houses in this world, two red and one green.

There are 9 levels in this world, and, unlike normal worlds, does not have a tower level. There is also only 3 normal levels on the main path in this world, contradictory to 5 to 6 levels in normal worlds. Levels in this world (other than World Flower-Rainbow and World Flower-Cannon) can be based on any theme. There is also a Ghost House in this world. There are also two secret levels which the players have to find the secret exits for. The world ends, as always, with the castle level, where Lemmy Koopa, the boss of this world, is waiting, unless the player takes the path to the cannon, which will lead to World 6 when completed, allowing the player to skip World 4 and World 5. However, if the player took the cannon in World Mushroom, then the player can also skip World 2 and World 3.

This course can be unlocked by beating any level in this world when the last two digits of the clock are "x88." 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 is a dusk level taking place in the high mountains. This level contains a lot of Warp Pipes, mini pipes, and Snake Blocks. The Snake Blocks enter and exit the area using Mini Mario pipes. There are also Goombas and Koopa Troopas. The player should note that none of these pipes can be entered. This level also has a secret exit, leading to World Flower-A.

Star Coins

 * Star Coin 1: The first Star Coin is early in the level. The player can use the Snake Blocks underneath it to reach the Star Coin.
 * Star Coin 2: The second Star Coin is before the Checkpoint Flag. The player should wall jump off of a Snake Block as it passes by the Star Coin.
 * Star Coin 3: After the checkpoint, the player will have to use the Snake Blocks to climb up a shaft. At the top are two blue Warp Pipes and a yellow Warp Pipe, with a gap in between them. The player should fall down the gap to reach the Star Coin. In order to get out, the player will need to wall jump back up.

Secret Exit
After Star Coin 3, the player should go to the yellow pipe and notice two ? Blocks. The player needs to stand on the right ? Block and then ground pound it. This will allow the ? Block to grow wings, taking the player to the skies. Then, the player should navigate across the Snake blocks to reach the Secret Exit.

The Secret Exit unlocks World Flower-A.
