Kings follower
The participants run around the area in a long row, with the King at the front. Everyone else has to copy the Kings movements. Its only the fantasy of the King that limits the movements.
But a few examples:
Animal (elephant, monkey, frog, mouse, crab, worm, or all gets fleas)
Humans: morning (lie down, stand up, stretch), runner, fencer, swimmer, rock musician, soldier, officer, nerd (sit down and relax), dancer.
