- Dancing rabbits in shootout games
In any rabbit shootout game, if you find anything that plays music (boombox, phonograph, etc.), shoot it. It will begin to play music. If rabbits get too close to the music player they will begin to dance instead of attacking you. Any rabbits far away will still try to attack.
