I don't know much about pins, but I think it has something more going on. It looks significantly different from any other pin I remember seeing.
We need more pics! I'd love to see pics of the parents, as well as the "normal" sibs. The one in the top right of the group picture looks interesting to me.
EDIT: I guess I forgot to refresh before I posted. Thanks for the pics of the parents. The only thing I notice is that some of the alien eyes on the mom are quite small. Not exactly the thing you'd look for to produce an eye-popping snake like that!
Thanks so much for posting pictures of the parents. The female has something hidden.... it is so exciting!!! Can't wait til next year to see what you'll do with mom and what else she produces!!
