 What is a piddly bear? Tell me what's a piddly bear. So let me start with growler bears because that's where the story begins. And growler 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 piddly bear, is when the mother is a grizzly bear and the father is a polar bear.
