New realm including a boss a new ore and new mobs!

How you get to the new realm is you make a nether portal made of amethyst with gold for the corner then you set it on fire. It has floating islands and less gravity. The new mobs are all flying phantom looking things. There are also iron golem looking things that are green with blue vines. Connected to anti gravity you can walk on walls and walk upside down. The ore is green. You can only craft armor with that ore. With that armor you can fly in the realm. Also with that armor if people come in a two block radius they get poisoned. They also have these green shards. If you break the shards you can craft a block. The boss is a three headed green serpent that lives in a temple. How you get to the temple is you jump in this floating yellow orb. When you get there the serpent will shoot poison balls at you. When you kill it, it becomes an egg. If you cover the egg in that green crystal block it hatches in one Minecraft day. And it becomes that flying green three headed serpent but you tamed it AND YOU CAN RIDE IT AND FLY AROUND ON IT AND MAKE IT SHOOT POSION BALLS though sadly you can’t bring it into the over world. And there’s this new green blue magenta wood.
