I have a bearded dragon and he, once he grows, will have a multi-level enclosure. I need to find a way to create a natural-looking cliff face that would act as a ladder to the other level. I was looking at the expanding foam stuf, but is there a way i can stick flat sones horizontally into that to make it look more natural? I am using those rep-tiles to create it, but if i strictly used those it would take so many of them. I need some filler material.
Another thing is what color are rocks in the outback? i have outback sand and was wondering what the natural color of it in the wild.
