Add Bears and/or Beavers, deer, or owl, moose, squirrel, badger. Or racoon

This would obviously make the game a lot more fun especially In the new biome and I'm sure many players and youtubers like myself would find this an insanely amazing update to the game if MOJANG were to overload this biome or just add one of these mobs the game wouldn't be so boring anymore and many players would want to hop on the game agsin
