Gold portal

Make a new portal. 4 blocks of gold at the bottom. 4 blocks going up of gold. 4 blocks going horizontally. 4 blocks of gold going down. Then put on an item frame and put bones on then do rotten flesh then make it go like that on the gold. Put underneath it water then light the golden fire. Then it will turn into a grey portal and when you go through it you go to a place where there are phantoms, skeletons, strays, skeleton horses and zombies and zombie horses.
