"SB-129" is a SpongeBob SquarePants episode from season 1. In this episode, Squidward accidentally freezes himself for 2,000 years and experiences complications while using a time machine.



Early one Sunday morning, Squidward goes to his window to play his clarinet. However, SpongeBob's alarm clock goes off at the same time, jamming Squidward's clarinet in his throat. SpongeBob asks Squidward if he'd like to go jellyfishing, taking Squidward's squeals of protest as a "yes." After dislodging the clarinet from his throat, Squidward finds SpongeBob and Patrick waiting for him. When he refuses to come out, Patrick realizes he doesn't want to play with them, but SpongeBob believes it is because he is still preparing to play with them and repeatedly asks him if he is ready.

Squidward asks SpongeBob why he is not at work, to which SpongeBob replies that the Krusty Krab is closed on Sundays. Squidward tells them to wait for him, closes the door, then sneaks out the back and heads for the Krusty Krab. It is indeed deserted, but SpongeBob and Patrick soon arrive calling for Squidward. He runs to the kitchen and hides in the storage freezer. When SpongeBob and Patrick cannot find him, they assume he is already at Jellyfish Fields and leave. Squidward tries to exit the freezer but finds that the door is locked; he assures himself that someone will find him soon enough.

Squidward frozen.

2,000 years later, Squidward is still stuck in the freezer, frozen in a block of ice. The door's rusted hinges give way and Squidward falls to the floor. SpongeTron, a robotic descendant of SpongeBob, sees the frozen cephalopod and thaws him out. Squidward is shocked to discover that he is in the future and begs for a way to get back to his own time, so SpongeTron directs him to a time machine. Squidward decides that he will travel to a time before SpongeBob has born, simply referred to as "the past."

The time machine arrives in the primordial sea. Squidward hopes that he can finally play his clarinet in peace, but he soon runs into a primitive sponge and starfish. The two remain curious about Squidward, but are soon distracted by a jellyfish, which they are frightened of. Taking his chance to get away, Squidward tries to play once more but is constantly interrupted by the screams of the primitives, who are zapping themselves with the jellyfish. Squidward has them tear pieces off their loincloths and proceeds to fashion jellyfish nets for them. Amazed by Squidward's demonstration of jellyfishing, the primitives take the nets in earnest.

Squidward all alone.

Squidward begins to play at last. However, the wailing of the clarinet aggravates the primitives and they chase him down. Barely making it back to the time machine, Squidward frantically jams the lever up and down and accidentally snaps it off, sending the machine hurtling through time and space before arriving in a world of emptiness.

Squidward is glad to have found a place where he can be alone, but hearing several disembodied voices repeating the word "alone," prove too much for him to bear. He frantically tries and fails to escape (repeatedly coming back to the same spot where he started). Desperate, he stomps on the ground in frustration and crashes through the floor and back into the time machine. Squidward breaks down sobbing and begs the time machine to take him home, saying that he even misses SpongeBob.

At his words, the time machine returns Squidward to Conch Street, where SpongeBob and Patrick await him. When they ask him if he is finally ready for jellyfishing, Squidward refuses and demands to know who invented such a foolish game. They remind him that it was, in fact, he who invented it, and Squidward, realizing he has inadvertently caused a temporal paradox, states that he is going back to rectify his mistake.

  • This episode was originally titled "SpongeBob 3000"[2] or "How I Learned to Stop Worrying and Love the Sponge."[3]

Animation cel marked with the "129" production code.

  • The episode's title, "SB-129," is its production code. "SB" stands for SpongeBob, and this was the 29th segment produced for Season 1, hence "129."
    • Model sheets, backgrounds, and animation cels for each episode are labeled with their production codes in the "SB-___" format. For example, "Squeaky Boots" was the second segment produced for season 1 and was marked "SB-102." "SB-129" is the only time the code was used in place of an actual title.
    • Even though the official name "SB-129" is the 29th episode in production order, it was actually the 26th episode in airing order.
  • This episode premiered on New Year's Eve in 1999 along with several other Nicktoons episodes with futuristic themes in celebration of the new millennium.
  • This is the first episode to use an animated title card.
  • This is the first episode where the words in the title card moves.
  • This is the debut appearance of Incidental 119.
  • This is the first episode where a time card is read out.
  • This is the first episode where the opening credits do not appear in an underwater background.
    • "Reef Blower" also applies technically, but it does not have any opening credits for that matter.
  • The man who reads the episode title card is an uncredited Doug Lawrence.[citation needed]
  • Apparently no one went in the freezer for 2,000 years so no one knew how Squidward went missing.
    • This could possibly be explained by Squidward returning to the present seemingly about the time he went missing, so no-one looked for him.
  • The present-day before Squidward sees the world after two millennia is set on March 6, 2017, which was the future when the episode originally aired.
  • This was Aaron Springer's first episode as a storyboard director instead of a storyboard artist.
  • In the Serbian dub, the episode is called "SB-192." This is a pun on the Serbian TV channel B92, which originally aired SpongeBob in Serbia.
  • The German name for this episode is "Die Zeitmaschine," which means "The Time Machine."
    • The French name for this episode is "Voyages Dans Le Temps," which means "Time Travel."
  • The ending, which arises from Squidward time-traveling and inventing the game of jellyfishing, is a time paradox known as a causality loop. This occurs when someone is inspired or driven by an event to time travel and, whether or not intentionally, causes the event which will facilitate their initial time-traveling trip.

"2000 Years Later."

  • The "2000 Years Later" time card uses a recolored version of the background for the title card of "Pickles."
  • In Nickelodeon Southeast Asia, during the marathon of Squidward's big holiday contest, this episode was known as its original working title, "SpongeBob 3000."[citation needed]
  • When Squidward is in the Nowhere dimension, his footsteps make different sounds than usual.
  • SpongeTron mentions that he has 486 clones, one for each letter of the alphabet.
    • This means that over the course of the two millennia, 460 more letters have been added to the alphabet.
    • However, in the Russian dub, SpongeTron says that he has 500 clones.
  • In the future, the entirety of Bikini Bottom is covered in chrome, except for the hinges on the freezer door, the freezer's interior, the time machine's interior, and the Bikini Bottom civilians.

Surprised SpongeBob (primitive) meme.

  • The primitive SpongeBob from this episode became a meme in 2014 and became fairly popular in the spring and summer seasons of 2016. Specifically, the scene where Squidward says, "What are you simpletons doing?" and SpongeBob primitive turns around while making a surprised face.[4] Most people who use this meme often confuse him with SpongeGar.
  • In the Polish dub, SpongeTron is called "SpongeBot" and PatTron is called "PatrickBot."
  • The scene with the primitive jellyfish is shown before the play menu appears on the DVD main menu of SpongeBob Goes Prehistoric.
  • According to the Show Design special feature on the Nautical Nonsense and Sponge Buddies DVD, it's stated by Nick Jennings how this episode was originally going to be about SpongeBob and Patrick time traveling, but it was replaced with Squidward.
SB-129 137.png
  • This is one of two season 1 episodes after "Jellyfish Jam" with a small scene that tests digital ink-and-paint animation. In this case, the short scene of Primitive Sponge and Primitive Star drooling was done digitally.
  • A calendar in the future Krusty Krab lists the date Squidward was thawed as March 6, 4017. This means Squidward got stuck inside the freezer on March 6, 2017.

  • This episode is alternatively titled "SpongeBob 129" on various sources, including the old Nickelodeon website, the Nickelodeon official YouTube channel, Amazon Prime Video, Paramount+, and the PlayStation Store.[5][6][7][8][9]
  • This is the first episode where the Krusty Krab appears without Mr. Krabs, as it was closed at that time.
  • A clip from this episode was used in a Nickelodeon bumper aired on March 7, 2020, reminding the viewer to change forward their clocks for Daylight Savings Time.[citation needed]
  • This is the first episode where SpongeBob does not play a major role.
  • Three scenes in this episode would later appear in the season 3 episode "Ugh," specifically during the song "When Worlds Collide:"
    • SpongeTron saying, "I am SpongeTron" in a robotic way.
    • Squidward laying down and saying "Future!"
    • Primate Sponge and Prehistoric Starfish being confused and drooling after holding a jellyfish.

Cultural references

  • The episode title "SB-129" is a likely homage to the 1971 sci-fi film THX 1138.
  • The shot of Squidward's face after being in the freezer for 2,000 years is somewhat similar to the shot of Jack Torrance's face after freezing to death in The Shining.
  • The time machine in this episode looks similar to the TARDIS from Doctor Who except it does not look like a phone box.


One window on SpongeBob's house.

  • At the start of the episode, SpongeBob's pineapple house only has one window, as opposed to two.
  • Before SpongeBob's alarm clock goes off, it is facing the bed. When it goes off, it is facing Squidward.
  • Squidward wonders why SpongeBob is not at work. However, he should know the answer because they share the same work schedule.
  • Squidward was unnoticed by everyone in town while he was frozen, even though his face is visible from the freezer window and the possibility of someone encountering him in the countless years that passed.

SpongeBob's black tie.

  • When Squidward is running to the Krusty Krab, SpongeBob's tie is black instead of red.
  • Even though the Krusty Krab is closed, the doors remain unlocked.
  • When Squidward closes the freezer door, the doorknob disappears.
  • When Squidward exits the can opener room, there is a spot between his legs and his shirt flickers from blue to brown for a few frames.
  • When Squidward enters the time machine in the future, there is one red and one green light above the door. When he next exits the time machine in the past, there are two red lights at the top.
    • The first time Squidward enters the time machine, the switch reads future on the top and past on the bottom. The next time he enters, the two are reversed.
    • When Squidward enters the time machine, the doorknob changes sides.
  • When Squidward goes up to the bush where Primitive Sponge is, he puts one arm towards it, but in the close-up, he uses two arms.
    • Also, he would have needed to put his clarinet down. However, he does not put it down in the prior scene.

Squidward appears to be saying, "What's going on?" with no voice.

  • When the machine malfunctions just before it brings Squidward to Nowhere, during the scene with the color change effect, Squidward's lip movement does not match when he says "What's going on?" with no voice.
  • When Squidward runs in Nowhere, his clarinet disappears, but when he falls back into the time machine, it reappears. It then disappears when he exits the time machine.
  • When SpongeTron says "Hi PatTron!," it comes out as "Hi PatTon!"
