Any morph with the spider gene will have a wobble.
In some cases, it can be extreme in which the animal usually suffers. By extreme, I mean smashing into the sides of their tubs repeatedly, etc.
I have two bumblebees and they don't have a noticeable wobble at all. When it comes to feeding they are a little wonky but are able to eat like everyone else.
If the wobble is extreme, do not attempt to breed. Although if your spider gene Bp has a little wobble, that does not mean its babies will be the same.
