Teen-age Mutant Ninja Turtles is a tagging game that I use for K-3rd
grade.  You have four turtles and the rest of the class are foot
soldiers.  The turtles try and tag the soldiers.  When a soldier gets
tagged he gets into a arched-back push-up position.  Another soldier can
free him by crawling underneath him.  The object of the game is to freeze
all of the foot soldiers.
