Crystal Falls

The same day I snagged Crystal Castle, I also got Crystal Falls too!  This was also from She-Ra and one that I was not familiar with and obviously did not have as a kid.

So I took some pictures of some of my figurines with the set...hehe  Hey, that's half the fun!

I do remember seeing that you could put real water in it and it would come out like a waterfall, but I'm hesitant to do so because of the age of this set.  Still undecided.....any fans out there who have this, do you use the water part of it?  If so, does it work or will it ruin the playset?
