"Spongicus" is a SpongeBob SquarePants episode from season 6. In this episode, Plankton builds a coliseum and holds a gladiator show, but SpongeBob interferes when he finds out Patrick is involved.



In the beginning of the episode, Plankton decides to destroy the Chum Bucket and turns it into a coliseum, announcing to Bikini Bottom on a jumbotron that there will be free entertainment, promising guts, and glory available to everyone in now what is called the Chum Coliseum. The coliseum is a spoof of the Roman arena with its battles and gladiatorial games, complete with Plankton in the Emperor's chair and a toga. Soon, the Krusty Krab is devoid of its loyal customers, and Mr. Krabs and the crew go to the coliseum to find out what Plankton is up to. When they sit down, a giant lionfish is released and SpongeBob is excited about who will get mauled until he realizes the prisoner that will be going up against the lionfish is Patrick. To entice the lionfish into chasing Patrick, Plankton orders blood sausages to be placed around Patrick's throat. SpongeBob decides to help Patrick and turns into a gladiator, complete with armor and a chariot pulled by seahorses.

Lionfish vs. Patrick.

He soon catches up with Patrick and rescues him, but now the entertainment has turned into a chase scene that does not contain the blood and guts Plankton promises, even when Betsy Krabs wants to see "body parts." Meanwhile, Plankton is trying to sell chum to the crowd who are getting hungry waiting for the guts and glory. One of the spectators agrees to buy a chum stick, but is angered when Plankton tells her it will be $10. She angrily asks why she should pay $10 when Krabby Patties are only a single buck, which the overhearing Mr. Krabs agrees to. Plankton angrily tells her "You can't get entertainment like this at the Krusty Krab!" and states that the fight will be off unless she pays $10. She agrees and immediately gets sick from eating the chum stick, while the rest of the crowd, having had enough, get up to go. Plankton traps all of the customers by blocking off all the exits when they try to leave. He claims to have waited 20 years to see the number of customers Mr. Krabs sees every day and demands everyone to sit back down and buy his chum. They sit back down grumbling and the entertainment continues.

SpongeBob to the rescue!

Going back to SpongeBob and Patrick, SpongeBob discovers that the Lion Fish is chasing the blood sausages around Patrick's neck, not him, after witnessing the Lion Fish eat a sausage that was thrown on the ground. He throws the rest of the blood sausages and they land in a pile on Plankton. He freaks out, now realizing the Lion Fish is charging towards him. He quickly escapes out of a secret door he had placed in the coliseum, taunting the Sea Lion and calling it a "prissy feline." The Lion Fish smashes through the wall and chases Plankton, who runs for his life. After Plankton's failed plans, the Krusty Krab is back in business, but Mr. Krabs has raised the price of a Krabby Patty from $1 to $10. When a customer complains about it, Mr. Krabs points to the Lion Fish and tells him he can talk it up with his new "financial advisor." The scared customer then complies and orders the patty.

Mr. Krabs, SpongeBob, Patrick, and Squidward laugh altogether and then leave rather awkwardly one by one, as the episode ends with the lionfish roaring at the audience/viewers.

Running gags

  • Customers complaining about the food costing ten dollars instead of one dollar.
    • As a result of their complaint, there are consequences if they do not pay ten dollars, such as Plankton calling off the fight and Mr. Krabs telling Wobbles to speak to the "financial expert," which is the chained lion fish.

Episode references

  • Like the sea bear from "The Camping Episode," the lionfish is portrayed as a fish with a predatory animal's head and claws on the tips of its pectoral fins.
    • However, unlike sea bears, lionfish exist in real life, but they do not look anything like in the episode.

Cultural references

  • The title "Spongicus" is a play on words on the name of famous Roman gladiator Spartacus.
  • The coliseum that Plankton made is similar to the Colosseum of Rome.
  • The lionfish is a parody of the Nemean Lion from Greek mythology and a visual pun on real-life lionfish.
    • The lionfish also resembles Merlion, the national symbol of Singapore.


One of the frames when SpongeBob's tooth is yellow.

  • When SpongeBob gasps while cleaning the window, one of his teeth flicker from white to yellow.
  • At the beginning of the episode, SpongeBob warns Mr. Krabs about Plankton through a payphone in the Krusty Krab. However, the payphone disappears in later scenes and is not seen for the rest of the episode.
  • Patrick's toga is white, but in one scene, it turns green.
  • When the people leave the Colosseum, they wind up in the area of the arena. Plankton is also in the arena when vending chumsticks. In reality, they could not go from the bleachers to the arena; corridors would lead from the bleachers to the outside of the Colosseum.
    • Also, the chariot and the lionfish are not there.
  • Incidental 49 is forced to eat a chum stick, but when everyone is not allowed to leave and forced to eat chum sticks, Incidental 49 can be seen with another chum stick.

Patrick with pink lips.

  • Patrick's lips turn pink, instead of black, towards the end of the episode.
  • The cash register is not at the counter at the end of the episode when everyone is laughing around it.
  • At the end of the episode when the lionfish roars and it shows the Krusty Krab, the clam sign is not there.

Erroneous non-inclusion of copyright information on the Nickelodeon Productions logo.

  • Along with its sister episode "Suction Cup Symphony," there is no year or copyright information anywhere in the end credits.
  • After Plankton destroys the Chum Bucket, part of Mr. Krabs' shirt becomes transparent.
