Strangely, making the drum fall asleep during this song will work, but it won't give the heartbeat.
A 16-Beat Attack! is battle theme in Mother 3. However, unlike regular themes, this one only plays when the Beaten Drum decides to change the default battle theme, Tough Zombeat. The song itself sounds like a sped up version of Zombeat but without the supporting cymbals. Before the music changes, the game will announce "The Beaten Drum did a sixteen beat attack!". The song istelf is a quick drum roll.
A Marching Attack!
A Marching Attack! is another theme than can play when the Beaten Drum changes the music. Before the music changes, the game will announce "The Beaten Drum did a marching attack!". The song is a simple drum roll, similar to the beginning of Isn't This Such a Utopia?!. As with A 16-Beat Attack!, there is no heartbeat track.
