NUNU BOT!
Lets be honest, the only reason to get the Nunu Bot skin is for the laugh. The model is alright, It's kind of awkward seeing a robot throw a snowball, but the laugh is golden. Unfortunately I cant justify 1820 rp for a laugh. I could however justify 1820 rp (or more, wink wink) for a Nunu Bot skin that had a nuclear explosion (mushroom cloud and everything) when his ultimate went off. Maybe shoots a slow moving rocket instead of the snowball or something. But the big ticket particle would be his ultimate.
