"Mermaid Man and Barnacle Boy II" is a SpongeBob SquarePants episode from season 1. In this episode, SpongeBob wins a conch shell in a contest to summon his heroes.



The episode begins on one Saturday morning, SpongeBob is watching his favorite show, The Adventures of Mermaid Man and Barnacle Boy, while eating Mermaid Man and Barnacle Boy Bran Flakes. He has entered a competition and is listening to see if he has won the mystery prize. The announcer pronounces the winner as "SpringBoob SquirePin," for his life-sized Krabby Patty mannequins of Mermaid Man and Barnacle Boy. SpongeBob calls out that "SpringBoob SquirePin" stole his idea before the announcer announces that he has made a "slight" error in pronunciation and that the real winner is indeed SpongeBob SquarePants.

Within seconds, SpongeBob's prize is delivered to him. SpongeBob has won the conch signal, a conch which has a noise that is a signal which Mermaid Man and Barnacle Boy respond to. SpongeBob blows the shell and Mermaid Man and Barnacle Boy hear it from Shady Shoals, springing into action. When they arrive at SpongeBob's house, Mermaid Man at first thinks that SpongeBob has been disfigured before Barnacle Boy recognizes him and points it out to his crimefighting partner. SpongeBob explains to the duo that he won the Conch Signal in a contest and that there is no danger; he is simply seeing if works. They then explain to him the importance of the signal and tell him that he must only use it for major emergencies.

Later on, Mermaid Man and Barnacle Boy hear the conch once again while showering and rush to SpongeBob's house, where he appears to be dead on the floor. However, he then reveals that he simply is having trouble opening a jar of mayonnaise. Barnacle Boy is annoyed by this, but Mermaid Man reminds him that emergencies do not come around as often as they used to, and he tells SpongeBob that he can blow the conch "every once in a while." However, SpongeBob ends up constantly calling Mermaid Man and Barnacle Boy to help him with normal everyday tasks. Eventually, the two heroes are exhausted and Barnacle Boy confiscates the item and yells at SpongeBob, who is now in tears and apologizing, explaining that he just wanted to spend time with them. Barnacle Boy ignores his pleas and attempts to destroy the conch signal using his iconic 'Sulfur Vision', but cannot bring himself to do so out of weariness.

Mermaid Man stops him from scolding SpongeBob and tells SpongeBob that the conch signal is too great of a responsibility for him. Instead, they let SpongeBob join them on their daily patrol, with SpongeBob dressed as a superhero.

They do various activities, such as keeping lookout from on top of a tall building. While patrolling the streets in the Invisible Boatmobile, Mermaid Man and Barnacle Boy see an old man, who was once the Atomic Flounder. The two joke about how he could possibly return to villainy before SpongeBob attacks the old man, taking the joke seriously. They stop him as he states his misconception, not understanding that the man is no longer a villain or threat. Angered by this revelation, the former Atomic Flounder pushes SpongeBob off of him as he yells at the heroes and blows atomic breath in Barnacle Boy's face, disintegrating it. The fumed old man then storms off from the heroes.

"Are you up for another ride in the invisible boatmobile?"

At a diner, SpongeBob asks Mermaid Man and Barnacle Boy what they will do the next day before they ask SpongeBob to find their theme song on a jukebox. As he tries to find it, they both remark he is a good kid but a pain and decide to "ditch" SpongeBob. Outside, however, they are attacked and trapped by their nemesis, the Dirty Bubble. When SpongeBob finally finds the song, which is the special dance mix version, he comes outside to tell them and sees their predicament. He asks the Dirty Bubble for his autograph, saying that he is his favorite super villain, and accidentally pops the Dirty Bubble with the tip of the pencil, saving the day.

The trio then ride off in the invisible boatmobile, and closes the episode singing a Mermaid Man and Barnacle Boy-themed version of "Jingle Bells."

  • This episode was originally titled "Twenty-five Words or Less"[3] or "25 Words or Less."[4]
  • Upon meeting with SpongeBob again, Barnacle Boy says, "It's just that sponge kid again," referring to when he and Mermaid Man met SpongeBob in the first "Mermaid Man and Barnacle Boy" episode.
  • In this episode, the Atomic Flounder appears as an actual flounder. However, in "The Bad Guy Club for Villains," he appears as a mutant.
  • It makes it look like the Dirty Bubble died at the end of the episode, but he later returns in "Mermaid Man and Barnacle Boy V." So, it would actually mark his first "defeat."

A slipper or Gary covering Mermaid Man's crotch as a form of censorship.

  • For the first time on the show, there is censorship. When Mermaid Man comes to SpongeBob's house to open a jar of mayonnaise, he is naked except for having his slippers on. When he is rushing into the room, one of his slippers is covering his crotch. Then once he stops in place, Gary just so happens to be in front of his crotch. Barnacle Boy quickly proceeds to grab a towel to put it over his crotch and then Gary moves out of the way.
  • This is the first Mermaid Man and Barnacle Boy episode to not have "The Lineman" as the title card music.
  • This is the first Mermaid Man and Barnacle Boy episode that does not feature Patrick.

  • This is the first appearance of the Mermalair.
  • This is the only season 1 episode to premiere during SNICK.
