"Mermaid Man and Barnacle Boy" is a SpongeBob SquarePants episode from Season 1. In this episode, SpongeBob and Patrick learn that their heroes are retired.



SpongeBob and Patrick look at the journey of the famous superheroes - Mermaid Man and Barnacle Boy. They decide to visit Squidward, who is annoyed by the antics of his friends. By calling Squidward Reflecto, SpongeBob and Patrick learn that their characters actually live in a nursing home and have long since retired. They decide that such crime fighters have nothing to do in retirement, and come to the Shady Shoals nursing home, where they are met by its caretaker. He escorts the friends to the superheroes. SpongeBob tells them that superheroes should not be retired, but they should fight evil. Mermaid Man creates a panic when he hears the word "evil." Meanwhile, the caretaker of the nursing home arrives and throws SpongeBob and Patrick out.

"What is going on in here?!"

While the evil fighters are going to the cafeteria for lunch, SpongeBob arrives and makes an inspiring speech about how superheroes should not be retired. While SpongeBob is telling this, the caretaker comes again and throws him right out to his house.

Barnacle Boy tells SpongeBob he will not come out of retirement.

SpongeBob and Patrick come up with a new plan to free the superheroes from retirement: SpongeBob, disguised as a woman, drops his bag, and Patrick, disguised as a criminal, steals it. Suddenly, Barnacle Boy comes to SpongeBob and says that they will always be retired, because there is no evil. Mermaid Man interrupts him and replies that there is always evil. They start arguing, until SpongeBob interrupts them and says that he and Patrick have painted their invisible boatmobile. Barnacle Boy decides to end the argument and rubs Mermaid Man that evil is right in front of them. It shows their rings, which resume their superhero activities, and the evil fighters get into a fight with SpongeBob and Patrick, who are admired from there. Mermaid Man and Barnacle Boy do everything possible to remove unwanted guests: Waterballs, Raging Whirlpool. And finally, for the third time, they are lucky: they are helped by elderly residents of a nursing home, who pick up SpongeBob and Patrick and throw them back into their homes.

Eventually, a show of Mermaid Man and Barnacle Boy is created: New adventures of Mermaid Man and Barnacle Boy. The Duo play checkers, then suddenly, the phone rings. Mermaid Man picks up the phone and thinks the phone is broken and hangs up. And then, the voice on the TV says: "Will our heroes ever get their phone fixed? Tune in next week and find out." After watching the new episode SpongeBob enjoyed it as he thought it was better than the old show, and when SpongeBob winks, the words appear: "Wink!"

  • "Mermaid Man and Barnacle Boy" was ranked #37 during the Best Day Ever event from November 9–10, 2006.
  • Currently retired critic Paul Pritchard of the DVD Verdict, in a review of 10 Happiest Moments, said that this episode "stood out" for him from the rest, by calling it "the perfect encapsulation of everything that makes SpongeBob great." He also praised Mermaid Man for getting "some of the funniest lines in SpongeBob history."[2]



  • This episode marks the first for several things:
    • The first appearance of Mermaid Man and Barnacle Boy (hence the title).
    • The first time SpongeBob is seen in drag.

  • When SpongeBob and Patrick are first asking the man at the front desk to see Mermaid Man and Barnacle Boy, an article on the inside of his newspaper reads, "School Drop Out Rate Soars." This has a double meaning, because "school" is also the name of a group of fish.
  • The old captain is played by Don Newhouse, the man who guarded the gates at Nickelodeon Animation Studio in Burbank, California at the time. He later reappeared in "Sun Bleached" and is also the inspiration for the character "Old Kid" from Invader Zim.

  • This is Mark O'Hare's first episode as a writer.
  • Atlantis is first mentioned in this episode before making its first actual appearance in the episode "Neptune's Spatula."

  • When Mermaid Man says "To the broccoli!", his right bra strap turns orange for a split second.
  • When Mable comes outside after Mermaid Man says, "sea creatures assemble," the bottom of her cane flashes white for two different frames.
