Quarrel Bear was a female polar bear that PewDiePie encountered.
When PewDiePie tries to approach the baby, Quarrel Bear believes that he is trying to hurt her son. In rage, she attacks PewDiePie. After being strangled by a rope while being dragged around in a boat and countless other tortures, Quarrel Bear is finished off by an arrow. PewDiePie then brings Quarrel Bear's baby in, naming him Polarn.
