You play the part of a light crazed moth. You must hit as many light bulbs as possible before the lizard climbs to the top of the wire and short circuits the whole house.
Be careful not to hit the UV Lights, as they pack a large jolt enough to kill a moth.
Hitting a bulb sends a small electric shock to the lizard causing him to drop back down the wire a short way. Try to get the 100 Watt bulbs, they give more points and knock the lizard down more.
