Kaliningrad was a city of Kenigsberg once and became a USSR enclave after the WW2. The large portion of the Russian army and fleet were located in Kaliningrad. There’s nothing special when you see a large group of Soviet military in the zoo, theatre, or any other entertainment location. It was a common practice to grab soldiers and bring them to whatever cultural event to entertain and boost the morale. But this white bear seems to dislike either this soviet practice or just warm weather. We guess this animal would rather relocate to the location of this kind.
