Minecraft wither

What's black, has 3 heads, and is the reason that Nate is close to be disqualified from my team? That is right! A wither! The wither are hostile mobs in Minecraft and the second boss in the game. While the Ender dragon is #1. How you make the wither is placing soul sand in a t shape and putting 3 wither skulls on top. Don't be fooled that Mr. three skulls has 3 heads. They are projectiles! In death, they drop a wither star. And then, I like it that you have to build the wither because these 3 heads creep me out!
