Vagina isn't a dirty word, you can say it, but yeah Mid-wife probably works better... Or "Ooba Droid" is my preferred name since for some weird ass reason it says that... "Oooba... oooooba..."
WTF is that about? Anyway, I'd take one and the Vader 2-1B-ish droid. I'm all about wonky background droids and aliens mixed into the line. Troop Builders always get my preferential treatment, but yeah the background characters are what make this one of the broadest toy lines ever.
