Grizzly started this really unfortunate habit of rinsing his rear-end with the water bottle. It took us a while to figure out what it was. At first we thought he was just scratching himself with it. But we felt sorry for Bean whenever we'd see him do that right before Bean went to take a drink from it.
It is cute, though, that Grizzly uses his one white foot to scratch himself. It's the only white on his whole body.
