Hmm...this reminds me of a part in NERD's ball python book. He says that many ball python "lords" (his term, not mine) in Africa will find something weird, start breeding it on their own and then sell the offspring to americans as "Oh, I just found this running around in the wild. You will be the first and only to have it". I wonder if this was the case with the pastels?
He also says that because of this process there are probably morphs in the possession of these ball python lords that we have never even heard of.
