"Mermaid Man & Barnacle Boy VI: The Motion Picture" is a SpongeBob SquarePants episode from season 4. In this episode, SpongeBob and Patrick find out that a Mermaid Man and Barnacle Boy movie is in production and are using actors, so they make their own with the real heroes.



SpongeBob and Patrick excited about the Mermaid Man and Barnacle Boy movie.

In the beginning of the episode, SpongeBob and Patrick are at a Mermaid Man and Barnacle Boy fan club meeting, where they learn that a new movie will be made based on the heroes, and meet the actors who will be portraying them. SpongeBob is very furious that the movie is using actors instead of the real Mermaid Man and Barnacle Boy. The actors state that this is an action movie and that the real Mermaid Man and Barnacle Boy are too old for action, resulting in SpongeBob telling the fan club that they must boycott the movie. He insults the actors, but this gets him and Patrick thrown out of the building instead.

The two then go to Shady Shoals and tell Mermaid Man and Barnacle Boy that Drippy Brothers Studios is making a movie about them and using actors. The heroes find the news horrible, with Mermaid Man crying as a result, and Patrick suggests they make their own movie, which they agree with. After brainstorming ideas at the Krusty Krab, SpongeBob and the crew meet to make the movie. SpongeBob is the director, Squidward is the makeup artist, Sandy is in charge of using the dynamite for explosion scenes, Patrick is the camera operator, Mr. Krabs caters the crew Krabby Patties, Pearl is the leading lady and the invisible boatmobile, and lastly Mermaid Man and Barnacle Boy are the stars of the movie. While they are filming, Plankton appears to audition for Man Ray, but SpongeBob tells him that Man Ray is not in their movie, so he gives Plankton the job of working the microphone instead. Mermaid Man has trouble with one of his lines, which takes 5,003 takes to get it right. A scene is filmed where Mermaid Man and Barnacle Boy ride Pearl up a steep mountain to Kelp Thing's hideout. Pearl is too heavy to pull and slides down the mountain, crashing into the sets.

Everything is destroyed, and Patrick reveals that he had accidentally been filming with the lens cap on. (SpongeBob: "PATRICK!" Patrick: What? I didn't want to loose it.") Now they have no footage to work with. SpongeBob goes berserk with frustration, eats worms, and cries since all the work he did for the movie was ruined, but Mermaid Man convinces him to finish the movie.

Mr. Krabs holds the premiere of SpongeBob's production in his restaurant, hoping to make lots of money from the movie. The members of the Mermaid Man and Barnacle Boy Fan Club attend, but only because the movie from Drippy Bros. Studios was sold out. The movie is then shown. SpongeBob plays with a car near a box with "Lox" on it. Then the patty vault is opened and Kelp Thing comes down, wanting to steal the Krabby Patties. But then Mermaid Man, played by Sandy, attacks him. He and Barnacle Boy unite, ending the film.

The movie proves to be terrible, and the fans are not pleased except for SpongeBob and Patrick. However, Mermaid Man is glad that SpongeBob proved that he and Barnacle Boy still have some "action" left in their old bones. They then laugh happily due to their efforts, as the episode ends.

Running gags

  • When someone says "boom" in a sentence, the scene changes to Sandy preparing to use a detonator, with Mermaid Man and Barnacle Boy in the background. She asks "Did somebody say boom?" and pushes the detonator. Mermaid Man and Barnacle Boy blow up.
  • A close-up of SpongeBob's mouth saying "actors" using a live-action human mouth.


The episode was confirmed by New York Post on February 23, 2005, revealing that Ernest Borgnine and Tim Conway will be reprising their roles for an untitled Mermaid Man and Barnacle Boy episode.[4]
