There would be at least 2 hides receded into the topsoil layer, possibly with a tube connecting them? One would have moss in it to be a humid hide, the other would have something like aspen or orchid bark. I'd want these to be made of something sturdy and not too far down, visible from the front so I could see if something started rotting. He loves to burrow so either that, or a section full of something like aspen that would be free for burrowing in.

He'd also have 3+ surface hides- one secured to the back or side, near the top, for heat and climbing purposes. I think a cork tube would be good for that, or one of those plastic box hides that I could cover with cork flats. I'd put one of these near the river, with sphagnum moss in it, positioned to be warmer than the underground humid hide, and one on the other side of the enclosure with maybe a bit of leaf litter. Then a hide on the ground made of slate tile or something similar, to be cave-like, and/or possibly one fashioned from cork to look like a tree stump!


This all looks too complicated.

You want everything, EVERYTHING! accessible and easy to take out and clean. Personally, I would just get some hides that look like caves, and add some texture that allows you to maybe grow moss slurry on them. I hide the hides under large sheets of tree bark. If the bark gets pooped on, I can just break that part off, or replace it.

This whole setup will be probably too humid as is, and even with no water features, you will NOT need a humid hide.
