If you spam Bebop's 1 while it is winding up, it queues the sound multiple times.

Spamming Bebop's 1 while it is winding up will cause the sound to queue up and begin to play multiple times. If you just press the button once, you hear both noises at the beginning and end of the animation just once. If you hit it multiple times, you will hear multiple clicks at the end of the animation and the beginning of the animation.
