figured it out!! and it explains why no body's heard of that!
boy do I feel silly for freaking, with out thinking, but the green is what threw me off,
Ralf was choosing security over temperature once I introduced his second hide, he was STAYING on the cool side cause that rock was smaller and he felt more snug and safe in it, sooooo, I took each hide and cut out a card board "wall" pefectly shaped form roof to floor, and scotch taped it in there, Buuuuut, cardboard looked guaty, and Ralf thought it was Tacky J/K!
So I took a crayola magic marker and colored his new wall black so you see no card board, which by the way he now uses both rocks and fits a perfect coil in each.
But he did his shed w/o leaving the hide(crawling in circles) so I guess the 75% humidity moistened things up and he rubbed all over his magic marker wall.
