I think you should just paint a baseball red and add some black in the middle for the eye. For the third leg, well, just use cardboard boxes or a pipe cylinder if you're feeling incredibly lazy.
Without her eye and third leg, SHE'S NO LONGER OKUU! How are people gonna identify you're Okuu if you don't put in those?!
What about wings?
Oh I've got wings. The reason I feel like I could get away without the third arm and eye is because of the pants that I made myself, they have that distinct arrow pattern that's on her skirt.
The thing that bothers me is the design on her shirt, I get the feeling that making an eye is actually simpler than making that pattern, but then again without the pattern the eye feels kinda out of place :/ Bah I'll figure something out eventually, at least the pants are
stylish
