After removing all your clothes, you climb into the pool. It's cool but not shockingly cold, and an underground spring somewhere feeds in a stream of bubbles.
The water comes up to your chest and the bottom of the pond is a deep layer of squishy mud. You wriggle your toes as the mud oozes through them. It feels soo good. There are also lots of weeds at the bottom which brush against your legs. You lean back against the rocky bank and relax.
Suddenly you hear footsteps approaching. Not wanting to be caught in the pool, you try to climb out - only to discover your feet are stuck in the mud and your ankles are tangled in weeds! You'll never be able to extract yourself in time!
Luckily the rocky overhang hides you from the path and the footsteps fade away again. They don't seem to have noticed your clothes either. You'll be able to stay here for hours without being caught, so you relax again in the invigerating waters. You're not going anywhere for a while...
