Description of feature
So since the bones and the Command Block which are located on top of the structure were pretty much inside the Wither Storm, it would look quite better if there were some tainted planks/stone/sand/cobblestone blocks (and maybe even some tainted dust?) around the command block and tentacles, to make it look like the F-Bomb ripped the body open so the Command Block could get exposed.

I did something similar like that in a gigantic Wither Storm corpse I built myself:

oh yeah and heres a video for uh better visuality i guess like you can see how it looks like what i built

Here's one design that I thought would look good.

Implemented in 2.2/3.2

that first one was epic honestly

yeah well I tried my best with the bones but thanks
