Trivia

 * The Dark Humans in this episode are called the Darkfishes.
 * To make the episode more kid-friendly, SpongeBob slays the Darkfishes the slapstick way.
 * Instead of being killed, The Darkfishes runs off.
 * This episode doesn't contain the usual "Opening credits" ocean so rather, the Opening credits scene resembles the ending credits scene from Velocity: The Dark Human Slayer.
