Somehow Claire Brtewster has been put in charge of the school's Foreign Exchange Club, and selects a student from Scandanavia to come to Peaceful Pines. However, the student turns out to be female, nicer and more attractive than Claire, so a jealous Claire sets out to deliberately humiliate her. In retaliation Lydia, Beetlejuice and the rest of the Neitherworld gang decide to teach Claire a lesson by making her a foreign exchange student to "Scrungylvania" and making her follow all the "local customs".
