From what I've read you go around the Magic Kingdom looking for Captain Hooks hook, that Peter Pan has stolen from him, or I also think there is a story line with Alladin. There's a surprise at the end. It sounds really cute. I know they make you do silly things while walking around or skipping, playing follow the leader.
Something different someone who's done it could descibe it better I'm sure.
