actually, it DOES. at least, according to namco. i mean, just look at pacman world 2, pacman the hannah-barbara cartoon, even the new pacman ghostly adventures (which totally sucks) shows pinky as a chick. oh!
Oh, ok then. I guess it does make sense since Pinky was confirmed to be male in the old Pac-Man cartoon series. (However, Pinky was reintroduced as a Female in the Pac-Man World video games.)
