Thank you for bringing this up, it is true that some Woma Ball Pythons wobble, but it is not believed to be genetic like the Spider. However it is still unknown why it happens with some Womas and not others. Also, you are correct that there are no issues with the Hidden Gene Woma, just the regular Woma, the only known issue with the Hidden Gene Woma is that their super, the Pearl, fails to thrive.
