There is nothing wrong with a Spider that has a wobble or corkscrew - they act like any other Ball python would and the wobble is genetic. I have not seen the wobble with my Spider at all, but I could really care less if he did happen to have it. Don't freak out about the wobble, it's just a genetic thing with all Spiders and there is nothing wrong with them having it. It is not a disease and does not make the Ball python unhealthy.
