Do me a favor, since you're such an obvious fan of the show (I'm basing this on your screen name) maybe you should look at the credits at the end of the first 2 seasons. Then come back and review your original question.
Question: I've seen some weirdo interpretations of your original and its starting to bug me about this, hopefully you could answer so I can silence stupid arguments I've had, what are the things all over him? Are those supposed to be spikes or sensory thingies?
that makes sense, but I don't think my stupid friend is going to take the same answer I've been giving him for the past two days. Can you make a ruling?
