Polar Bear

Polar bears 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 may 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.

Their swimming speed is faster than the player's.

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

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.
