Who am I?

Well, here is a short description of me... I am a very free spirit. I've been known to go with the flow and be very chill. Sometimes I can give off an icy demeanor but most people warm up to me eventually. I'm also a clean freak. I hate being dirty. I'd also like to say that I am some what of world traveler. I've been everywhere to the polar ice caps to Victoria Falls in Africa. I'd like to visit Mars one day but we'll have to see how that goes.  

Who do you think I am?
