I have a reported import girl I named Dirty Josefina after Dirty Joe. Was really bummed when he didn't prove. I may finally get babies from her and her pastel son this year but I'm not expecting it to prove as I don't think any of the other IMG's have. But you got to try just in case. I think at least some that are called IMG are the changer phenomena where a snake suddenly turns axanthic looking in one shed. I've heard a few theories on why that might happen but nothing that sounded definite. My girl was 688 grams and looked like a true ghost when I got her so don't know if she might have hatched normal and suddenly changed or not. She soon started to pick up a cream color in her dorsal stripe and the increased dark IMG look. The constant blurriness of her lower sides is the main thing that gives me some hope she might be something genetic.
