Bowser Jr. Showdown

Bowser Jr. Showdown, or Meringue Clouds-, is final course of Meringue Clouds in New Super Luigi U. It is unlocked by completing Ludwig's Block-Press Castle and its own completion unlocks Magma Moat.

Layout
Luigi will hop up onto a cloud that will move when Luigi lands on it. Some Parabombs and Brick Blocks are ahead. Some more Brick Blocks will be moving up and down. Some Brick Blocks, Cannons and a Red Ring appear before a Cannon Pipe which will send Luigi onto the actual airship. There, he will encounter Cannonballs, Cannons, a POW Block, Bob-ombs, and a Cannon Pipe which leads to Bowser Jr.. He will be in his Junior Clown Car, and it will grow boxing gloves, which can crack the blocks. After Luigi jumps on him or throws Bob-ombs at him three times, he will fall. Luigi will celebrate, then the blocks will fall, along with Luigi. Bowser Jr. will command the fist to crush Luigi, but Luigi runs out of the way, destroying the airship instead.

Star Coins

 * Star Coin 2: After the first set of moving Brick Blocks, this Star Coin is hidden in the cloud.
