The players form a circle. One player is taken into in the middle and is blindfolded, they are the bat. Two more players are then taken into the middle and are blindfolded they are the moths. The bat has to catch both moths. To do this the bat shouts ";BAT"; and moves one step. The moths shout ";MOTH"; and moves one step away from the bat';s sound. When a moth is caught they are out and pick someone to be a moth for the next game, when the bat has caught the last moth they choose someone to be the next bat. Everyone should be a bat and a moth at least once.
