I finally managed to finish all of them! The necks still have a few imperfections, but this is honestly the best result I could manage with my current skills.
This Mod includes the regular Ananta enemies and NPCs, as well as Alpa (does anyone still remember her?) and Shanti.
Mmm~ for their sake, I basically had to force the Bibo+ body into a snake shape...
But I have to admit, they do look pretty nice when they start twisting around, hahahaha~
