Sit in a circle at maintain a steady beat (bang on your knees, clap your hands, click with your left hand, click with your right hand, repeat). The first person says on the beat "One frog" the next says "Two eyes" then "Four legs" then "Into the puddle" then "ker-PLUNK!". The number of frogs increment each time the frogs jump into the puddle, so the next sequence goes: "Two frogs", "Four eyes", "Eight legs", "Into the puddle", "Into the puddle", "ker-PLUNK", "ker-PLUNK". I hope you get the drift. If someone says the wrong phrase/number or is too slow or misses the beat then they are out. The game ends when there is a single winner.
