Follow the water.
From Create Your Own Story
Strange lights bother Fred. He wants nothing at all to do with them. Where the water is, is where Fred wants to go.
Fred follows the water through a very curvey passageway. As he gets farther from the source of light, he is forced to light a torch to see.
In the distance he sees a pool where the water appears to be heading. In the middle of the pool is a treasure chest, floating just above the water.
