Biome Updates

Some biomes can get a little plain, y'know? Sometimes you just explore so much that it's just plain. I think we should update some new biomes, like the Jungle biome. I think there can be more interesting mobs there added. 

Or maybe, oak forest update; Squirrels, deer, or something like that to make it a little more interesting. 

I just thought this idea would be cool :)
