Answer:
Airships in Super Mario Bros. 3 are the Koopa Kid's way of transportation. Although it's design is quite ridiculous, it can fly. It is basically a large boat or ship with several propellers. Defending the Koopa Kids are two strange creatures, the Rocky Wrenches, and Mini Bowser-Bots. Plus, there are cannons and fire engines, which both damage Mario. Once Mario enters the silver pipe at the end of the airship, Mario and a Koopa Kid are locked in battle. Every Koopa Kid's weakness is their head. Jump on their head three times, and the Koopa Kid will hand over the magical wand.
