Description of feature
You should remove the 2 Big Tentacles after the witherstorm gets formidibombed so that it looks similar to the Witherstorm in MCSM while retaining Crackers Witherstorm Look, and make it when it gets 9 heads that the 2 Big Tentacles regrow back.
You could also make it a Config Option to make the tentacles disappear when formidibombed and regrow when it gets 9 heads.
Phase 6 after formidibomb:

Phase 6 After it gets 9 heads and the 2 main tentacles Grow back:

These images i found on the internet cuz i dont know how to put screenshots on github but you get my point.

ONLY ONE FEATURE REQUEST PER ISSUE

I like this idea, would kind of look weird without them but would kinda make sense too, after such a big strong blast of an F-Bomb. May I add that it would be cool too that the tentacles convert into tainted flesh blocks and stay on the ground, as if they have been cut off? Just a side idea.

IIRC, crackers said he wouldn't make any changes to the body and tentacle models for now, but id recommend you just wait and see for what he has to say

Gonna keep the tentacles attached. Don't really feel like messing with the look of the existing phases too much.
