How many times has your penguin waved to another penguin? Maybe to say hello, or to say goodbye! But have you ever noticed that you only wave with the penguin's left flipper, not the right. TIP: The penguin's flipper, not our hands. The penguin is facing us, so it is opposite to what we see. Struggling with your left and right? Don't worry! Just make an L shape with your hands so your thumb is pointing out and your second finger is pointing up. Do this to both hands. The one which reads "L" is your left hand.
