Airships are shaped identical to large wooden ships, however instead of sails they have propellors. On the front of the airships are usually Bowser's face. In New Super Mario Bros. U, each Koopaling got a personal airship which was smaller in size and had the respective Koopaling's head and features on it.
The Koopaling Airship appears in the last World in New Super Mario Bros. 4 as the Tower Boss (alongside with Bowser Jr. To defeat the airship, Mario must jump on a Koopaling when he or she jumps out of the airship to attack him. Once all the Koopalngs (and Bowser Jr.) are defeated, the Koopaling Airship will spin out of control and explode, giving Mario the key to the final course, Bowser's Castle. Please note that as every Koopaling is defeated, the next one is more difficult to jump on.
The Airship is the signature court for Bowser Jr. and the inside of the Airship is a signature stage for Boom Boom and Pom Pom. The court is on top of a Airship and the goals are floating by some propeller things. You can fall if the Airship and if your character dies so it takes a while to respawn so be careful. The inside is the same but you can’t fall off and the background is different.
- The official Prima Games guide for New Super Mario Bros. Wii calls the airships "Sky Ships."
- Princess Peach can be found on the airship in one of the official artworks for Super Mario Bros. 3; however in the game, she only appears in the secret room where she is locked in when Mario rescues her in the end after defeating Bowser.
- In Super Mario Galaxy, whenever the player spins near the doors of the airship, a coin will pop out.
