I know Cass. I thought about removing it. KD has a penchant for odd sculpts, and compared to some of the more recent ones (like the Forge God), this is tame!
It's not a wang, it's like a longer version of the inner mouth from Alien. Meant to eat wangs, apparently. From KD's site:
"She has a mouthed cord growing from her belly that devours male organs of her mates to better the chances of divine conception."
My concern with cutting and sculpting is that her stance reflects a elephant trunk between her legs. If I cut that out, she's going to have one hell of a gap.
