Is this just for boys or can the girls become a pirate as well?

I'm going with some friends and they have 2 kids who are Pirates of the Caribbean crazy - (I'm quite partial to Jack Sparrow myself )

Anyhoo, I mentioned that I thought there was something at one of the parks that they could do and I've been pestered ever since The cheeky things have even said I can be their pirate mum - hence my name

Any help would be great.
