The End

The end is full of endermen, and one of the bosses, THE ENDER DRAGON. Once you have reached the end, you will spawn in a tiny little room. You might think theres an exit somewhere in your little room. But there is NOT. So don't forget to bring a pixaxe with you. When you reach the surface, you will see tall poles made out of obsidian and a spinning square on each. Every time the Ender Dragon flies by, you'll see it shoot something at it. Those things heals the ender dragon so be sure to destroy those first and then the ender dragon. You might try to hit the ender dragon with a sword. DO NOT do that. Even a dimond  sword can't hurt the ender dragon a tiny bit. The only way to hurt it is with ARROWS or with SPLASH POTIONS.  You cant go back to the overworld unless you kill the ender dragon or fall off the edge of the world.
Now I will tell you one thing that almost everyone wants to know. People ask what does the ender dragon drop once you kill it. the answer is......LOADS OF EXPEREINCE!!!!!!
