Make a Minecraft Earth Update

Minecraft, I have been a long fan of this amazing game you have created, the biomes, the mobs and the message you leave in this game. I want you to please make an Update dedicated to Minecraft earth and adding all those mobs that were in the game to be in a new place. Many of this mobs work as variants for the other mobs such as cows, sheep and chickens. This helps make Minecraft a bit more alive in the biomes because I've noticed that some biomes feel deserted with no mobs around them such as the dark oak forest, savanna, etc. This mobs can make Minecraft more fun and more creative. Please give a good thought about this idea, Minecraft earth may be gone, but Minecraft still lives. Please, the Minecraft Earth mobs should not be left forgotten.
