Post Ender dragon events

After you kill the Ender dragon. New things should happen. For example. Endermen’s eyes should be green to show that they are no longer controlled by the Ender dragon. They should also say thank you in that weird Ender man voice. And they could place valuable blocks by the player like gold block, lapis, and red stone blocks, as a gift. If you respawn the Ender dragon, the Ender men’s eyes should glow red and attack you on sight until you beat the Ender dragon again. This is to show that they are mad at you for summoning it back into the world. And also to make the fight a little bit harder so people have to come up with new strategies to killing the dragon.
