Everyone is saying that there is no way that he could have been frozen, so I'll assume that he wasn't frozen (although he was stiff, I am sure of that, that was not my imagination). And whether I warmed him up over the course of 2 minutes or 2 days, all that really matters is that he survived. I'm glad that things worked out the way they did, because if I had done something different, I might be saying "hey I got a dead snake in the mail today".
