SS Brass

The S.S. Brass is a flying boat made out of instruments. In Dance Dance Revolution: Mario Mix, Mario (or Luigi and Toad) use it to fly across the Mushroom Kingdom to get the Music Keys. The songs "In The Whirlpool", "Step by Step" and "Always Smiling" are set on the S.S. Brass. The main form of propulsion, powered by the trumpet-like turbines, gets revamped into trombone-like turbines after the player defeats Pirate Lakitu in Fishing Frenzy.
