Cast out your fishing line and reel someone in from the circle to you. When you pull her to you she will flop like a fish. The fish and the fisher person will greet each other once the fish is reeled in.
Plan for Success: Model and practice what casting a fishing line and reeling someone in would look like as well as what is appropriate flopping.
Variations/Extensions: Put the heel of your hand to your neighbor's hand. Flop your fingers on the wrist of your neighbor as a fish would do. Greet your neighbor as you flop.
