Fun-in-the-sun on a remote tropical island turns into a tropical treasure trove of tricks and treachery for the Simpsons, when Mr. Burns sends them on a wild secret substance chase into the cream-filled center of an international scandal. Then, Ned takes a psycho-diddily- pathic turn for the worse, and Bart and Lisa enlist Rainier Wolfcastle to uncover the truth. Also, witness the Apu’s incredible 96-hour shift at the Kwik-E-Mart and a western adventure starring Homer Simpson.
