World 3-Airship, also known as World 3-6, is the sixteenth level of Super Mario 3D Land.
Mario begins the level by trying to pass by a giant spiked pillar that launches itself at Mario, similar to those found in forts and castles of Super Mario World. These pillars then retract to be launched again seconds later, and they appear throughout the rest of the level. Mario must traverse small floating platforms, dodging these large machines in order to get to Boom Boom at the end of the level. After passing by a couple of the giant pillars, Mario finds the Checkpoint and proceeds onward past spiked balls and Bob-ombs. After the Bob-ombs is a group of ten spiked pillars that Mario must swiftly run past, and upon reaching the far side of these pillars, Mario finds and fights Boom Boom.
- Star Medal 1: Left of the first giant spiked pillar is the first Star Medal, on a floating platform.
- Star Medal 2: In the middle of the large group of spiked pillars is a small basket-like platform. It is where the second Star Medal is found.
- Star Medal 3: The final Star Medal is found on the very tip of the final airship, the airship with the Flagpole.
Enemies that appeared in World 3-Airship:
The battle with Boom Boom is very similar to that of the previous battle in the world 2 airship. The only real difference is that the ground in the room begins to move left and right.
