After a slime pit appeared in his driveway, Dean Fitzroy had enough of Tri Kuppa Bro's pranks. When he made arrangements to expel them, three of the frat brothers hired the Ghostbusters. Fitzroy later aided the Ghostbusters in identifying the leader of the real culprits, Elwin Spalding. He accompanied them to the girls' dorm where they enticed the ghosts with graduation. At the fake graduation ceremony, Fitzroy gave a quick speech then Ray trapped them. Dean Fitzroy apologized to the frat but Peter pulled the bucket of water prank on him.
