A “Grolar Bear” or “Super Bear” is a cross between a grizzly and a polar bear

As arctic ice melts, grizzlies and polar bears are coming into contact more often and so “grolar bears” are becoming more common. They are like grizzly bears but bigger and have the stomping and hurling abilities of polar bears.
