When you're playing multiplayer and one of the players runs out of lives mid-level, he or she can still contribute to the game from the Great Beyond. Each direction of the D-pad is mapped to a different sound effect. Hold a direction and hit the 1 and 2 buttons to trigger different sounds, including clapping, a horn, kick and snare drums, and of course cowbell. The unfortunate players waiting for the level to end can add a drum line to the music.
