Go to the office supplies and grab a bottle of liquid glue. Watch the "Employs Only" door until the janitor comes out with the floor mopping stuff. Wait until he stops then walk up to him and say, "Somebody threw up in the ladies room" and when he walks away to check it, pour the glue into the mop bucket.

Get a map of Narnia and go in and ask random people how to get to a certain place, like Cair Paravel or the Lampost.
