Bowser's Castle (Dance Dance Revolution: Mario Mix)

"Bowser's Castle" is a playable song in Dance Dance Revolution: Mario Mix. It is a remix of the music for the Mario Kart: Double Dash!! incarnation of Bowser's Castle.

It appears as the final stage of Story Mode, Bowser Battle, soundtracking Mario or Luigi's contest with Bowser to get back all four Music Keys. Unlike most Story Mode danceoff opponents, Bowser does not behave like a second player. Instead, Bowser can be seen dancing in the background of the song in all modes, standing on an elevated stage in the middle of the titular location.

This song's only Mush Mode gimmick is Rockets, which are exclusive to it. Pieces of a Rocket will appear as notes, behaving normally until stepped on. When stepped on, they will move to the bottom of the screen, to the side of the area where notes appear. Stepping on three Rocket pieces will assemble the full Rocket, which will land next to Bowser, open its base up to reveal a hammer, and hit Bowser over the head with it. When done enough times, the rocket will instead wind up for a full swing that smashes Bowser through the ceiling, creating a hole through which fireworks can be seen. This must occur by the end of the song to defeat Bowser; if it does not, the player will fail the song regardless of the state of their dance meter.
