World 2-Castle (New Super Mario Bros. 2)

 is the castle of World 2 in New Super Mario Bros. 2. The level is spent nearly entirely on a platform that only moves if the player is stepping on it. Podoboos and Fireballs will attempt to lurch out and hurt the player in this level.

Layout
The player starts out on a flat surface, where the moving platform is docked. After jumping on the moving platform, a few Buzzy Beetles will be encountered, moving around on Brick Block structures. When the player approaches the structures, they fold out, dropping the Buzzy Beetles onto the platform. Soon after, Thwomps appear. The player can bait these Thwomps into crashing into lava, destroying them. Shortly after, the Midway Flag appears along with two ? Blocks, one of which has a Super Leaf inside. Another platform is docked here. The platform quickly approaches a quad of fireballs and the second Star Coin rotating above. The level's Red Ring is located directly after this, floating above a set of Brick Block structures. Shortly after, a dual set of fireballs and a red pipe appear on-screen. After a few more sets of fireballs, the boss door appears.

Boss Battle
The boss is Iggy Koopa, riding around in his Chain Chomp carriage as a cowboy. The battle plays extremely similar to his Castle battle in New Super Mario Bros. Wii. The player must stomp him on the head three times to defeat him.

Star Coins

 * Star Coin 1: The first Star Coin coin can be seen right above the second set of folding brick block platforms. To reach it, use the platforms that are under the Star Coin.
 * Star Coin 2: The second coin is swinging back and forth on the ceiling. The player can either use the springboard (from the nearby ? block) or they can try to jump for it.
 * Star Coin 3: The player will need the springboard, hiding in the ? block near the second Star Coin, to reach a red pipe in the ceiling. In this area, the player should run to the left and hit the P-Switch in the left block. This will allow the player to get the final Star Coin. Alternatively, the player can use the Raccoon Leaf to enter the red pipe.
