Move any obstacles to the side of the room, or clear an area outside. Instruct everyone to move around the space at a brisk walk, changing direction often but watching where they are going so they don’t bump into each other.
Then, call out the first command: Caterpillar. This instruction means everyone needs to get onto their hands and knees and crawl along like a caterpillar. Get everyone to stand back up and walk normally again. The second command is Butterfly: Beavers should flap their arms as if they are butterflies who are flying. The final command is Pupae: your young people should pretend they are going into a chrysalis by curling up on the floor and staying very still.
Vary the commands and pick up the pace to see who is listening, or turn it into a competition by eliminating anyone who is too slow or does the wrong action. The Beaver Scouts themselves can also become the leader of the game, giving instructions to their peers.
