Wither stars can't blow up. Well they can. Put one inside a chest or inventory or bundle or hopper or oven or anything that can hold an item. and set TNT around it and the chest or bundle etc... will blow up destroying the contents. but wither stars can't blow up. I would make it so when you do blow up it all blows up except for the wither star and it just drops on the floor.

Also I was fighting 20 withers and i killed one and it dropped a wither star a wither came and blew it up. A wither can blow up a wither star.

That is all. Any questions ask below.
