To Catch a Ghost 101

Casper High School is adding a new class to the curriculum this Winter. Ghost 101, short for 'To Catch a Ghost 101.' Danny, Sam, Tucker and Valerie don't sign up for the class, but when they find their names on the roster for the new class when they get their schedules they are forced to take it. Maddie and Jack are the Teachers. What is Team Phantom going to do? Be very careful.
