I love the "crazy looking normal" oxymoron in the ball python world. Maybe if its "crazy looking" maybe its not "normal". Every mutation was once a "crazy looking normal". Obviously there are normal ball pythons that take on a crazy appearance due to incubation or developmental problems, but it's still important to closely analyze what you are seeing that is "crazy looking" and determine what is the CAUSE. In this case it's the spider gene.

I've seen spider hets for other genes that greatly diminish the white and pattern. I've seen het tristripe really change the patterning on spiders. As for what is effecting this spider is uncertain, and yes it doesn't look like a great example, but I absolutely see the spider gene there. And for me its actually obvious.
