The End Wither

I am just a beginner so, don't judge.

The End Wither is related to alot of Creepypasta articles. I seem to remember about a year ago, I was playing Minecraft Pocket Edition and I was going to The End to defeat The Ender Dragon. I wanted to spawn a Wither whilst the Dragon was still alive. I did, and got a little something different. This is where the End Wither comes in. I loved looking at it while it spun around in circles The Wither was black with purple dots. It looked like an obsidian texture.
