The Evil Beneath is the first half of the fifthteenth episode of season three. 


Jimmy, Carl, and Sheen are trapped in Dr. Moist's lair, who captures innocent tourists and turns them into Algae Men by inviting them to eat food with him. When they eat the green algae seeds they turn green, then into Algae Men. Which explains the rash of disappearances in the Bahama Quadrangle.


  • The Bahama Quadrangle is a reference to the Bermuda Triangle, a loosely-defined region in the western part of the North Atlantic Ocean, where a number of aircraft and ships are said to have disappeared under mysterious circumstances.
  • Jeff Bennet would later use the voice he used for Dr. Moist for Dorkus on Planet Sheen.
