Was Moose a man or a woman?

Was Moose, the owner of the concession stand, male or female – or perhaps a little of each? Each time I saw him and/or her, I became distracted by the androgyny.

Even the actor's name, Mickey Fox, leaves questions. I see Mickey was born Helen Fox, so I guess at one point she was female, but I really couldn't tell from this film. Not that there's anything wrong with androgyny.
