The Mini Me is a mob added by the OpenBlocks mod. You can summon it with a Golden Egg by placing the Golden Egg and waiting a while. Note that the Golden Egg will cast a small explosion on spawning the Mini Me, so the player should not place it near valuable blocks. The Mini Me looks like a one block tall version of the player who placed the Golden Egg.
It will follow the player around and pick it up automatically. While being carried, the player can control the Mini Me in the same way as Horses. By looking in the direction it wants to travel and pressing the walking keys, the Mini Me starts to move. The Mini Me can be dismounted by pressing Shift.
