All except one squad stand on one side of the play area.
These are the fish.
The remaining squads form the net.
The leader of the fish calls out : "Fish swim!"
All fish swim toward the net.
The net clasp hands and try to capture as many fish as possible into their circle.
All the fish that are caught in the net become the dreaded net loops (They are now part of the net.)
How many fish can avoid being caught?
