So i was wondering if there was any particular reason that sometimes some of the rocks in this pool are covered with water and then other times they are not. Does anyone know if this has something to do with a puzzle?

I think it's just the tide coming in and going out.

Thank you, Mbee. That explains the gold fish mystery. lol
