"Plankton's Regular" is a SpongeBob SquarePants episode from season six. In this episode, Plankton learns that he has a regular customer who visits the Chum Bucket daily.



Plankton is once again complaining about how he has no customers, with Karen being annoyed by his constant whining. Nat Peterson instantly comes in and asks for a chumstick. Plankton at first thinks he is kidding, then Nat says he was serious, then Plankton gives Nat the chumstick. After Nat eats it, he says it is so good, he would come back the next day. Plankton is overjoyed by that fact and brags to Karen, who is barely shaken by this. Plankton decides to wait with a chumstick for Nat. Eight hours later, Plankton is woken up by the clock and realizes it is closing time and concludes that it was a lie that Nat was coming back. However, at that moment, Nat appears. Plankton gives him the chum he had been saving, which Nat thinks is perfect after it looks like he thought it was a very appalling meal. Nat says he will come back the next day and the next week, telling Plankton he has a regular customer on his hands.

Plankton's Regular 151

At the Krusty Krab, Plankton appears and Mr. Krabs tries to squish him with a spoon. Plankton assures Mr. Krabs that he does not need to compete with the Krusty Krab anymore since he now has a regular customer. Mr. Krabs laughs at him and shows off all his customers eating Krabby Patties. Then Nat appears asking Plankton for another chumstick in front of Mr. Krabs. Nat carries Plankton back to the Chum Bucket, with Plankton mocking Mr. Krabs and insulting him.

Mr. Krabs explains the situation to SpongeBob and orders him to get Nat to eat food from the Krusty Krab and not at the Chum Bucket, but every attempt is unsuccessful. Mr. Krabs bursts into tears, saying that he cannot afford Plankton to have even just one customer. SpongeBob says that if he wants Nat to eat at the Krusty Krab, he will have to make chum as good as Plankton. This gives Mr. Krabs the idea to steal the chum recipe.

That night, Mr. Krabs sneaks into the Chum Bucket trying to steal Plankton's recipe but Plankton catches him with the spoon security system. SpongeBob then grabs Plankton and starts talking about the irony of the situation, but Plankton then uses the spoon security system on SpongeBob as well. After Plankton reveals the name of his system, Karen shows on screen that Nat is heading for the Chum Bucket with a fortune. Nat comes back telling Plankton that the Chum made him sick twice since he only pretended to like the food so Karen would pay him so that

Plankton would stop complaining. Unfortunately, Plankton feels miserable again and realizes that he actually never had a regular customer. SpongeBob tells Mr. Krabs to escape, but Mr. Krabs decides to stay and laugh at Plankton's misery.

  • This is Nat's biggest role to date in the series.
  • This is the first episode to have one of the Bikini Bottomites as one of the main characters.
  • Nat's first name is revealed in this episode.
    • In "Missing Identity," when Nat is at work, they say his name was Peterson. It has now been confirmed that Peterson is his last name.
  • Plankton started waiting for Nat at 10:00 A.M. and ended at 5:57 P.M. That is three minutes before closing time for both the Chum Bucket and the Krusty Krab.
  • When Nat goes to the Chum Bucket the second time, he eats two chumsticks, but he only paid for one.
  • Foreshadowing: the first clue that Nat actually hates Plankton's chum is when the second time he goes to the Chum Bucket, he looks like he hated it, but he lies and says: "It's perfection!"
    • The second clue is that he said he does not like Krabby Patties and he said he does not have any friends but in one scene, he can be seen sitting at the Krusty Krab, eating a Krabby Patty with other people.
    • The third clue that Nat hates Plankton's chum is when Mr. Krabs makes Nat eat his brand of chum. When Nat eats the new chum, he says that it was the "second foulest thing he had ever tasted." He was likely referring to Plankton's chum.
      • This also proves that Plankton cannot even make better chum than Mr. Krabs', which is the only thing he is good at making.
  • This is the second episode where Mr. Krabs steals other formulas. The first is "Best Frenemies."
  • This episode contradicts The SpongeBob SquarePants Movie as in that movie, Plankton says that he never had a customer. However, in this episode, he does.
  • In the game SpongeBob Moves In!, one of the quest arcs involving Plankton is extremely similar to this episode's events.
  • Nat is seen eating chum again in "Chum Bucket Supreme"; however, that time is only because he enjoyed saying the slogan "Chum is Fum" despite still being disgusted by the food.



Plankton shouldn't have gotten the chum stick.

  • When Mr. Krabs shows his customers to Plankton, Nat is seen in the background as one of Mr. Krabs' customers despite being Plankton's customer.
  • When Nat goes to smell the Krabby Patty, there is no animation that shows him bending over and after he wipes his face when SpongeBob got his face greasy.
  • When Karen is shown taped to the wall, there is tape over her screen, which restricts her speech even though she has no mouth.
  • When SpongeBob tries feeding Nat the Krabby Patty, the cheese is missing in the next scene.
