Most Spiders will do a corkscrew/spinning of the body & wobble their heads. In some cases they can majorly have it, and other times they don't have it as bad. Sometimes, they won't have it at all, but that doesn't mean that they don't carry the corkscrew & wobble in their genes. Some Spiders that don't show it at all will sometimes show it when they are stressed.
This gene can be spread to the offspring, and even normal Ball pythons can get this if one of the parents are a Spider and does happen to carry the corkscrew & wobble in their genes. So, if you bred a Spider to any other morph, the other morph in the offspring could even get it because it has the Spider's genes, if that makes sense. Even if the parent doesn't show the corkscrew or wobble, it could still have it in its genes and pass it on to any of the offspring.
