Also, I've never heard of a trend of facial deformities in champagnes. I believe you may have been misinformed.... champagnes DO, however, sometimes exhibit neurological issues that are very similar to the issues with the spider gene (wobbling, spinning, listlessness).
Though these issues hardly ever affect the animals ability to thrive as a "normal" ball python, some people speculate that it is the reason, when affected animals are bred together, that the offspring super spider, super champagne, and spider champagne cannot survive outside the egg.
