World 7-Airship (Super Mario Bros. 3)

 is the airship level and the fourteenth and final level overall of Pipe Land in Super Mario Bros. 3. The level becomes accessible upon completing 2 and its own completion unlocks the way into Dark Land.

Layout
Like with the other airship stages, Ludwig's airship autoscrolls horizontally. Ludwig's airship is made up of several platforms with Bolt Lifts that can be used to jump across the gaps, along with Rocket Engines and Rocky Wrenches that the player needs to avoid. After the first Bolt Lift is a ? Block containing a power-up. After the second and the longest Bolt Lift is a wall the player needs to slide under, and a power-up is placed above it. Afterward are several small platforms with Bolt Lifts at the ends, followed by three Bolt Lifts that will travel backwards when stepped on before the Warp Pipe to Ludwig. Like with the other Koopalings, Ludwig fires his magic wand to attack and is defeated after jumping on his head three times. However, after Ludwig comes out of his shell after jumping on him, he will charge at the player, which will paralyze them for a short time.

Once Ludwig is defeated, a letter from King Koopa, or a Koopa Troopa in the PAL NES releases, will be shown saying he has the princess locked up in his castle.

Trivia

 * This is the only airship level to have huge square windows at the stern of the ship (the other airships have small circular port windows).
 * In the Super Mario All-Stars and GBA versions, the cursed king is a crowned Yoshi instead of a Pirahna Plant in the NES original version.
 * The letter from Bowser at the end of the level has a picture of Bowser only in the All-Stars and GBA versions.
