You went to the Tabony key and put all the rocks in the little slots? And you still can't find them? Hmm......Are you sure your in one of caves on the water and you are running around inside? When you finished the puzzle, did a little word box pop up and say something (which I forget what)? Did the room shake after putting all the rocks in the slots?
I know its a lot of questions, but answer these, and you'll solve your problem. And WOO! First Post.
