Very unique, I've never seen a spider with spots, but it's definitely a spider. And as far as the wobble, anything with the spider gene (not the spider name necessarily) will have a wobble from barely noticeable to horrible. Some outgrow it, and some get worse, it is the luck of the draw. I have a very soft spot for spiders, I love them specifically because of the wobble and awesome patterns. My little girl is just the sweetest thing when she looks up at me with that wobble, I just want to squeeze her lol. Congrats though, your spider is definitely unique looking.
