List of episodes

"The Secret Box" is a SpongeBob SquarePants episode from season two. In this episode, SpongeBob wants to see what is inside Patrick's secret box.



SpongeBob is running towards Patrick's house, ready to go jellyfishing. Patrick says he'll go with him, but must put away his "secret box" first. SpongeBob asks him what's inside the box, but Patrick refuses to let SpongeBob see. Despite repeated attempts, SpongeBob is unable to get Patrick into opening the box, even after he tempts Patrick with secrets of his own. All that is known is that whatever is in the box is extremely funny. SpongeBob eventually gives up and decides not to look.

That night, SpongeBob finally snaps and sneaks into Patrick's house and tries to sneak a peek while Patrick sleeps. He makes several noises, but Patrick doesn't wake up. However, SpongeBob accidentally speaks, and Patrick wakes up and catches him in the act. He is shocked, and declares their friendship to be over. But, Patrick ultimately forgives him and opens the box. Inside, there is just a piece of string ("A secret string!" as Patrick describes it). SpongeBob comments on how he "should've known," but when he leaves, Patrick reveals to the audience the real secret; when he pulls the string, a secret compartment opens in the box, and there is "a embarrassing picture of SpongeBob at a Christmas party" the audience doesn't see. Patrick then tells SpongeBob "Merry Christmas."

  • It is revealed that SpongeBob and Patrick's symbol of friendship is a ring that sings, "It's the best friends forever, best friends forever, ring!" When a button is pressed, it has dancing figures of SpongeBob and Patrick.
  • This episode is referenced in the "Under My Rock" song.
  • According to an interview with Stephen Hillenburg found here, the idea for this episode came from this quote:

"The idea came to Drymon because he, too, had a secret box as a child. "He started telling us about it. We wanted to make fun of him and use it."

  • Running Gag: Every time SpongeBob steps on or bounces onto Patrick's house floor, it causes a loud noise.
  • This is the first episode to use a real image as part of the title card instead of a drawn one.
  • The sound effect heard when the box is falling on SpongeBob's knees can be heard in this episode accompanied with a Warner Bros. stock sound effect, on "Dexter's Laboratory," "The Powerpuff Girls," "The Powerpuff Girls Movie," and an episode of "My Gym Partner's a Monkey" called "Guano in 60 Seconds" despite the Cartoon Network program's APM Music containings.
  • This episode reveals that SpongeBob and Patrick had been friends since they were babies.
  • The design of Old SpongeBob seen in SpongeBob's fantasy of Patrick and himself being old was used again in "Goo Goo Gas."
  • This episode's basic plot line bares a striking resemblance to the 'Dharma & Greg' episode "The Box" which aired just eight months before.
  • In Polish version, this episode called Super tajne pudełko which means The Super Secret Box.
  • This episode aired four days before the 9/11 tourism attacks, along with "Band Geeks."
  • In the 2005 movie War of the Worlds, Rachel, Tom Cruise's daughter, is shown watching the episode on TV. However, the audio and video are out of sync.
  • This is one of the few episodes to have just Tom Kenny and Bill Fagerbakke as the voice actors. Another one is "Rise and Shine."
    • Also, both this episode and "Rise and Shine" only feature SpongeBob, Patrick, and Gary as the characters.
  • Patrick's line "Duh!" and his face is a popular internet meme.
  • Patrick's line "The inner machinations of my mind are an enigma." and the milk spilling has become a popular internet meme.
  • A lot of scenes from this episode have been used on YouTube.
  • The end of the episode is foreshadowed earlier in the episode when Patrick pulls on SpongeBob's tongue, just like how he pulls the string on his secret box.
  • SpongeBob claimed he has never been late for work, but he is late for work in "New Digs." It is possible that this episode took place before that one.

Cultural references

  • Patrick says "Hands off, peeping Bob!," a possible reference to the phrase "peeping Tom."
  • When Patrick mistakes SpongeBob for the Clam-burglar, it is possibly a reference to a McDonald's character, the Hamburglar.


  • Squidward's house was missing near the end of the episode. This also occurs in "InSPONGEiac."
  • The potato chip on the floor that SpongeBob stepped on is in one scene, but in another scene, it is missing.
  • In this episode, SpongeBob is drawn as a lighter shade of yellow.
  • When Patrick says, "And to think we joined the 'Best Friends Forever' club?!" his purple eyelids disappear.
  • When SpongeBob gathers the "secret" stuff, he goes towards Patrick's House, not his own.
  • When the screen shakes, there is a light blue border. This error also occurs in "Welcome to the Chum Bucket" and "Band Geeks."
  • In the opening credits, the k in Carson Kugler's name is lowercased instead of capitalized. This also happens again in "Welcome to the Chum Bucket" and "Procrastination."
