Morph

All the participants gather in a large circle. One person is selected to be the initiator. That person chooses a motion and a noise. The person to their right must then imitate that motion and noise as accurately as possible. This continues all the way around the circle until it returns to the initiator. The key is to imitate the person directly to your left. If they slightly change the motion or noise in any way, do your best to imitate the new change.
