When Broken Bear's makeshift rocket fails and he falls back to Earth believing he is on another planet, he saves a bear from a zoo to take back to Earth with him. Finding a human-made rocket, he takes off. He leaves the atmosphere with the zoo bear and lands on another planet. The planet has 19 imprinted on its surface in lava, alluding to the number 19 imprinted on Broken Bear's fur.

Green bears occupy this planet, and Broken Bear believes this is his calling, to become 'leader of the space bears'. However, while inside the ship, he accidentally sets the rocket to launch and he goes back to Earth. The zoo bear, left on the space bear planet, is treated as the new leader.
