In the game The Works, two cards depict bears. One depicts the Barenkönig, the king of the bears, and the other depicts the Swartzwalders, and portrays a group of bears standing upright and holding weapons. Additional points in favor of this theory: the bears' Master is 1. someone who has been on Castle Wulfenbach and 2. been near Dimo's hat. That would seem to narrow it down to either Krosp or Agatha. Also, that crown that Konig has on a chain around his neck sure looks Krosp-sized.
