"Antarctica-like" island biome

It works just like the mushroom island biome (minus the mushrooms), it's a rare biome that's just one giant island filled with ice (packed/blue ice maybe), snow, powder snow, and icebergs! They could even generate igloos! As for the mobs that spawn, they can be polar bears (until you guys decide to add penguins to minecraft), white rabbits, and strays at night. Honestly this biome isn't too far fetched to add to the main game.
