My friend has a bumblebee with the worst wobble I have ever seen. She turns completely upside down when going to strike at her food then proceeds to eat it while upside down. And when she is in shed her head has been known to do loopy loops. With this being said the person has decided never to breed her because she doesn't want to take the chance that it breeds into the babies.

If you are looking into getting a spider morph just make sure you ask the breeder if they know how bad the wobble is and they should know. However just be aware that when you bring the bp home that the wobble might be more prevalent at first because of stress from the new environment. My Enchantress (the vanilla butter banana spider) my friend who bred her didn't really notice a wobble but once I brought her home the first night she did a loopy loop but since then she's been fine. She's only wobbled the once during feeding and missed and ended up grabbing the tail.

Enchantress is my sweetest bp and I love how the spiders morphs look. If you want one just go for it and get one from a reliable breeder. They have their quirks but so does every bp. My one normal will strike at you after every feeding I don't know why she just does. My cinnamon pewter doesn't like to ever lay in the warm side of his cage, he's always in the cool side even while digesting.
