Piranha Pond
The light sparkles off a small pool of water. It's fed by a brook that splashes and runs over stones and pebbles. As you kneel down to put your hands into the refreshing water, a hungry voracious fish jumps up, mouth agape and sharp teeth aimed at your fingers. You just manage to call out "fiddlesticks!" and feel a slight breeze as your hand vanishes right before the piranha closes it's mouth around it.

Better luck next time!
