OR youre snake just claimed himself a new hide.
My boa got stuck inside her hide 1 time. It was an upside down wicker basket thing that i cut a hole in, well 1 day I had a left over rat pup so i gave it to her. She snatched with just a quick strike out of her hide hole and 2 days later shes draging her hide across the tank cause only about 1/3 of was able to fit out the same hole. It was an easy fix and she wasnt harmed and didnt even seem to care or notice. I was lmao.
I would put the cooling fan in his enclosure rite next to his hide and call it a night.
