Exactly what Deb and OhhWatALoser said. It can be done, but there are risks. I was lucky enough to get a 4 year old that was clean, no duckbill or spinal issues.
They're out there, just really hard to find. I think people are just not breeding them because of the inherent risks. I know of one Super Cinny and an 8 Ball on this forum too. Actually there is another SBP hatchling that popped up recently. I totally get why you like them so much. I had to have mine when I found her. Just be careful, be patient, and know that you are going to most likely lay out some cash for one if you don't want to try breeding one yourself.
