its permenant - our son got picked last Oct

he was wearing a Jedi training cap we got in the Star Wars gift shop next door and a Star Wars t-shirt. We got to the area about 40 minutes early, stood on the line so he was at the front (he's only 5!) so the bigger kids were behind him and it was a scrum when they chose the kids but the hat clinched it
