Minecrafts version of Pokeballs

Ok so everybody wants an end update but what would that include ...

I think there should be a consumable item that alows you to capture mobs like a pokeball so in the late game you can have a easier time creating a zoo. This will not replace leads as you will get them later and you can make the "pokeballs" expensive to craft or rare. You cant lead hostile mobs and you have no way of transporting the bigger ones.
