World Flower-A

 is a level in World Flower in New Super Mario Bros. 2 that is unlocked by locating the secret exit in World Flower-1.

Layout
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. Further 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 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.
