We can always count on Ship/shore/lighthouse.
One end of the room is the shore, the other is the lighthouse and the center line is the ship. you call out any of the three and the scouts run.
If you yell out SURF, they drop to their bellies where ever they are. At the scout level the last to do as called is out. at cub level they don't care to win just to play for as long as you let them so no one is out.
Always love pointing to shore and yelling lighthouse.
Twice as much fun in the water.
