Momo is a polar bear, albeit with a human soul.
As a polar bear, Mo Mo was not strong enough. When he was about to starve to death, he met Li Bing, a photographer who came to the Arctic to collect photos.
Li Bing is not a Buddhist, but he is better than a Buddhist. His compassion for all living things is much more pious than ordinary Buddhists. Although he knew that polar bears were angry and cruel animals, he still chose to save Mo Mo.
