The player should be able to breed Polar Bears

The player should be able to breed Polar Bears. Polar Bears are neutral unless near a cub. By breeding 2 adult polar bears a baby polar bear cub would be created. This would turn the adult polar bears aggressive towards the player. They would be a very interesting dynamic for the player to have to handle. Upon growing up, the baby polar bear cub could drop a useful item similar to the turtle scute. Perhaps this polar bear fur could be used to make fuzzy pants that prevent the frost damage from powdered snow.
