sec...
heard of Brian Barczyk (I probably spelled his name wrong) from SnakeBytesTV? I tweeted him a photo, and asked him about the "fancy" thing. He clarified it's a spider.
Additionally, I had tweeted him a photo of my snake.
That at is just one of the online contacts. Another breeder is actually a friend I've known for a while online. She's not really a professional like Brian is, however she was the one who initially warned me about the spider wobble. Told me to watch out for it because some spider bps get culled if it prevents them from eating right.
And these are just the online contacts. Unfortunately, in person conversations don't come with transcripts, so I cannot provide proof there.
