Dirty little polar bears..

Picked up my card today at the zoo and went to see the little polar bears...you can see them from two sides one side is darker and its grass and soil that is why they do not look white.. on the other side is a pond where they can swim.... my first photo is when they where on the darker side and still dirty...an hour later I arrived on the other side.. see the extra photo... they are in the water playing and totally clean... its was fun to watch them play...
