Everyone stands in a circle and is put into pairs. Each pair is given an animal with a sound and an action. The animals are given out the in order that they're in the food chain (eg amoeba at the bottom and lion at the top). The lions make their noise and action and then make the noise and action of another animal. That pair then makes their noise and action and one of another animal etc. You can't make the noise of one of the animals next to you in the circle or of the one that passed it to you. If you do, your pair moves down to become an amoeba and everyone else moves up. The aim is to be a lion at the end of the game. Also, as the game progresses, you can become harsher and say that the pairs aren't allowed to hesitate or confer before making their noises.
