Im going to have a buzzer in my mouth that will make a sound when someone presses the button.
Jonathan is going to have his head rocking side to side using this little white piece from the little bits which makes it move.
Max is going to have EarPods that you can pull out of his mouth and listen to music or there might be a voice recording instead.
