Polar Bear

Polar bears are neutral mobs that will be added in Minecraft and to a future Pocket Edition version.

Spawning
Polar bears are found in snowy biomes.

Behavior
They can exist in a passive, neutral, or hostile state. The cubs are passive; adults are neutral, but they will become hostile if attacked. All adults within a 41×41×21 cuboid will become hostile towards the attacker if a cub is attacked. An adult will also become hostile towards a player within a 21×21×21 cuboid of the adult if a cub is within a 16×16×8 cuboid of the adult. They can attack not only players, but other mobs that accidentally attack it.

Their swimming speed is faster than the player's, making them difficult to get away from if they are attacking.

Polar bears attack by rearing on their back legs and then mauling down on the attacker with their front paws.

Polar bear cubs can be grown up quickly using wheat, similar to cows.

The adults can get heart particles using wheat, but adult polar bears fed wheat do not end up actually breeding.

Polar bears can be led with a lead.

Drops
When killed, a polar bear has a $3/4$ chance to drop 0–2 raw fish, and a $1/4$ chance to drop 0–2 raw salmon.
