Glazios - if you want to try toys, you go ahead, just use common sense about things that might hurt them. Mine seem to like things to climb on, and are certainly intrigued when I have a change around!
About the wet hide, I use sphagnum moss, can re-dampen it a good few times usually, unless your gecko chooses to make the damp hide a loo, as one of mine has! I used loo roll just last week when I ran out of moss, won't do it again, useless in my opinion. Dried out quickly and left bits on my gecko.
