I have a bumblebee boy (spider + pastel), and I really notice no wobble in him. He used to get it just a tad at feeding time when he got over excited, and he had problem landing strikes, but he's just fine now- though he does take his time waiting for "the right moment". He does do derpy things though- like he's the one to eat his food backwards, or slither off the bed, get stuck somewhere, etc, etc. The man calls him "our little retard", but he's basically both of our favorites (well, I don't have favorites, but whatever) because of how "special" he is. Maybe I say this cos I've never seen a "bad" wobble, but I love the spider gene and I think they make for amazing morphs / breeders / pets.
