The SS Brass is an airship with a musical instrument theme.
In Dance Dance Revolution: Mario Mix, Mario (and/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 SS Brass. The main form of propulsion, powered by giant trumpet-like turbines, gets revamped into trombone-like, or French horn-like turbines depending on the level, after the player defeats Pirate Lakitu in Fishing Frenzy. An unlockable minigame titled Fire Up the SS Brass involves maneuvering the ship through tunnels.
