HELP! Baby ball python extremely skinny and corkscrewing!

Yes, this is definitely jumping in quickly & learning the hard way...I'm not impressed with the breeder you found. A snake should never be sold in this condition- rescued perhaps, but not sold.

86* for that bathwater was still a little too warm; that's nearly as high as the maximum recommended temperature in their enclosures (you want the cool side to be roughly 77* & the warm side to be 88-89* max. warmth), & remember, in their enclosures they can always move away from the warmth, unlike in a bath where they're totally surrounded by whatever temperature the water is. I do hope he's okay, he's going to need all the help you can provide, it sounds like. Think of him as being in your ICU- (intensive care unit).

Don't handle him at all, as you might a pet- just watch & let him rest until he's eaten (& digested) AT LEAST 3 meals with you (& preferably after 5+ meals, with one in such poor condition) at normal intervals (5-7 days). In this case, if you get him to eat a fuzzy, I'd offer again after 5-6 days, unless he's in shed.*

*You said his skin is wrinkly- he might be wearing an old stuck shed, which you might need to help him get out of- but for now, keep his humidity up- about 75% (I hope you have a gauge? and also are using a thermostat on any/all heat sources?)

I see you've posted pics while I was typing- that helps us see what you're dealing with. He's a pretty little soul- & as Armiyana mentioned, he's thin but could be worse, & he doesn't appear to be wearing old shed, so that's good.
