 What is a Pizzly Bear? Tell me what's a Pizzly Bear. So let me start with Grolar Bears because that's where the story begins. And Grolar Bears are essentially a hybrid of polar bears and grizzlies. And that's specifically where the mother is a polar bear and the father is a grizzly. The opposite, which is the Pizzly Bear, is when the mother is a grizzly bear and the father is a polar bear.
