This is sooo cute! It's clear that your BP enjoys his soft hides a lot.
My BP loves soft things as well, he really likes to burrow/tunnel in blankets and comfortably coil up inside them. I could swear he particularly likes it when sheets are fresh as well lol. In the wild ball pythons are often hiding in tunnels with soft soil and they have soft scales/skin so it makes sense that they like soft textures.
I've considered giving my BP something soft in his enclosure but he'd probably pee on it and ruin it so alas I've had to stick with things that are easy to disinfect lol
