Snow White, I guess.
Do you have school?
Add a Bee Hive block. Acts as a spawner for Bees, effectively bats with smaller hitbox, that act as neutral mobs, attacking when provoked, or if hive is hit. Hive could produce honey, as a new food and potential potion ingredient. Similarly, ant colonies could be interesting. Black and Red ants produced from separate hills, hills produced by new queens, exponentially expanding bee hives and ant colonies, until the world is flooded with bees and ants, until all entities are now bee-ants, and the game becomes Bee Ant.
Maybe it would be a good idea to add a new creature called the Nether Stag.
Basically the Nether Stag looks like a stag beetle but with Nether aspects.
You know? Now that I think about it, I might need to work a bit more on that.
I was wondering when it would be added. And I never knew it was originally in Minecraft...
Sorry, I thought it said 1.9.0 releases. Instead, it's just another lame 1.8 update. .-.
