Circles of My Confusion

I love photos of surprisingly unlikely cross-species animal friendships (What the %@#! did I just say)? Anyway…looks like something happened between the penultimate and the last photo.  That Polar Bear looks awfully relaxed in the last shot;  all that’s missing is a cigarette dangling outta his mouth.  I wonder if we got a “Polar Dog,” or even a “DogBear” outta this little rendez-vous…
