Walkling

If there's an end update, then I would love for you to add the Walkling which is an enderman that walks in mid air with a cape. It doesn't have arms but it will use its mind to pick up blocks and throw them at you. It may be more fitting if it was a mini boss. When defeated the mob will drop a totem of void which can save you if you fall into the void but it can work for three times or once, you decide.
