Polar Bear

"Bears: adorable at a distance. This is true in Minecraft, just as it is in real life. They may look huggable and furry, but they are full of teeth, and not too fussy about what, or who, constitutes a meal."

- Marsh Davies

Polar bears are neutral mobs that live in icy biomes.

Spawning
Polar bears spawn in snowy tundra, snowy mountains, and ice spikes biomes, in groups of up to two. If there is a group of two or more, there is always one parent, and the others are cubs. They can also spawn in frozen rivers, deep-frozen oceans, and regular frozen oceans. Polar bears spawn at light level 7 or higher.

Polar bears can spawn on top of regular ice, but not packed ice or blue ice.

Drops
When killed, an adult polar bear drops one of the following: Dropped fish is always raw, even if the polar bear is on fire when killed.
 * $3/4$ chance of dropping 0-2 . The maximum amount can be increased by 1 per level of Looting, for a maximum of 0-5 with Looting III.
 * $1/4$ chance of dropping 0-2 . The maximum amount can be increased by 1 per level of Looting, for a maximum of 0-5 with Looting III.
 * from player kills

Like other baby animals, killing a baby polar bear yields no items or experience.

Behavior
Polar bears can exist in a passive, neutral, or hostile state. The cubs are passive; adults are neutral. They become hostile toward the player if they get too close to their cubs (this does not seem to happen as fast on easy difficulty).

If a cub is attacked, all adults within a 41×21×41 cuboid become hostile toward the attacker, regardless of difficulty (although in peaceful difficulty, their attacks do zero damage to players). Attacking an adult who is within a 16×8×16 cuboid of a cub also provokes other adults within a 21×21×21 cuboid of the attacked adult. Polar bears can be accidentally provoked by other mobs.

Polar bears also attack foxes.
 * $$, adult polar bears attack any fox that stays near it for a while, hitting it once (similar to how non-aggressive pandas and llamas attack a mob or player once, every time they are struck) every few seconds. Cubs, however, are far more aggressive and constantly attack foxes within 16 blocks.
 * $$, adult polar bears continuously attack foxes within 16 blocks (similar to cubs in Java Edition). Cubs do not attack foxes.

Polar bears attack by rearing on their back legs and then mauling down on the victim with their front paws. Their swimming speed is equal to the player's, making them difficult to get away from if they are attacking in water.

Polar bears cannot breed. Polar bear cubs' growth cannot be sped up.

Trivia

 * According to Jeb, polar bears were added after his son Björn was born. Coincidentally, "björn" is Swedish for "bear".
 * Unlike most other baby mobs, polar bear cubs have a unique sound effect that is not just a sped-up version of the regular polar bear sound effects; this is also reflected in subtitles.
 * Polar Bears are the first bears added into the game, later followed by pandas.
