This level uses the Hammer and Boomerang Bros., screen scrolling pipes, the animated falling water from the SMB3 underground tileset, coin outlines, the pipe cannon, ON/OFF blocks and the one-ride timed lifts. The powerup blocks contain a Propeller Mushroom if you're not small. There's also an airship-themed bonus level that teleports Mario if you fall down, and the goal cave level at the end (because the main level uses layer 3 clouds).
The airship bonus level:
Super Mario 3D Land: Main Theme by RednGreen
