Boarding the Airship

Boarding the Airship, or , is the final course of Meringue Clouds in New Super Mario Bros. U. Unlike other the Airship levels in the Mario series, this one takes place outside of the airship, progressing to the boss arena. Before the course starts, there is a short cutscene of the flagship engaging the player.

Layout
The entirety of the course is an autoscrolling level. The first section is similar to the final part of Iggy's Castle in Super Mario World, where a giant object periodically comes down to crush the player. However, unlike Iggy's Castle, Boarding the Airship's object is the giant mechanical hand that was used to toss the Mario Bros. and Toads to Acorn Plains. During the latter half of the first section, the hand will start punching the ground, destroying it in the process.

The second section takes place below the hull of the ship, and the player must use a platform that moves when the Wii Remote or Wii U GamePad is tilted.

The final section is the boss battle with Bowser Jr., in his Koopa Clown Car. Unlike before, however, Bowser Jr. equipped his Clown Car with boxing gloves, which destroy the steel blocks the player has to stand on, and Bowser Jr. himself tosses Bob-ombs, which the player can use to harm Bowser Jr. After three hits, Bowser Jr. is defeated.

A cutscene plays where the player drops onto the airship, and Bowser Jr. prepares to crush Mario, but he runs out of the way and the flagship itself is destroyed and crashes outside of the tornado ahead.
