Re "warm AND humid hide"- My little Aussie spotted python has such a thing- it's a large rectangular plastic food container that's about 8.5" x 12.5" long
and about 3.5" deep. I use similar humid hides for my corn snakes, but they like cooler temps so their humid-hides aren't heated, whereas my spotted
python loves the warmth, so her humid hide and also a regular hide are both over her UTH- her humid hide currently has damp orchid bark, but mostly
soaked sphaghum moss is best for this & what my corns have in theirs. (I switch things up now & then depending on what I have on hand.) My spotted
python uses her humid hide the most of all her hides (she has a cool one too) and it's essential for her to shed well...apparently these are a coastal species,
not desert. Anyway, I suspect your little BP would love to snuggle into damp moss with warmth... and I'm keeping my fingers crossed for his recovery.
