Wobble and corkscrewing are something that all spiders display in varying degrees at some point in their life. It's not been proven to be genetic, but mostly anyone who knows a Spider knows what i'm talking about.
It's nothing that impairs them by any means and it's not a sickness, just a quirky, funny trait about Spiders in general!
Thanks! And yes! The breeder gave me the index card that shows everything that went on with the snake while in his care. Top notch breeder!
