Description of feature request

I recently found this cool video on youtube, it contains all the wither storms sound effects from MCSM in high quality, so it would be pretty cool if CWSM sound effects were updated to be in higher quality too.

Now, my suggestion is that when the wither storm picks up a player or formidibomb, it should do a special "beastly growl" (https://www.youtube.com/watch?v=WONLuAHUeCU , from 3:12 to 4:10) and do its roaring animation without shooting a flaming skull. Why?
I just think it would be a small, but pretty cool detail.
