Mermaid Man & Barnacle Boy VI The Motion Picture 018
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 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 and insults the actors, but this gets him and Patrick thrown out of the building.

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. 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 isn't 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, meaning that they have no footage to work with. SpongeBob goes berserk with frustration 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 (as Sandy) attacks him. He and Barnacle Boy unite, ending the film. The movie proves to be terrible, and the fans (except for SpongeBob and Patrick) are not pleased. 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.
