The polar bear is the stronger and the slower of the two animals currently in the snow biome. The polar bear drops 2 winter fur and 3 raw meat upon death. The polar bear was added in the Winter is Finally Here update.
Since the polar bear is difficult to fight, it's recommended to avoid them altogether, or circle around a fire to and attack them once in a while without getting hit. (Note: this can be dangerous without proper technique) Another way to kill the polar bear is to lure them over to the border between the winter and the forest biomes and attack them from the forest side since they cannot cross the border.
