Cross the pond via the stones
	Fall in the water
	Not all stones are safe

The contestant has to get from one end of a long pond to the other, using the stepping stones spaced across the water.
All of the stones look identical, but not all of them are fixed in position. Some stones aren't supported and will sink when trodden on.
Super version
Balls are fired at the contestant, from cannons, as they make their way across. If they successfully reach the other side of the pond, the game isn't over as they move straight on to play Bridge Ball.
