Plankton had pieced together his own creation using memory and science.

Plankton's chum is the signature ingredient in all of Plankton's menu items. As one of several major factors that causes the Chum Bucket to attract no customers, the taste is highly considered foul in contrast to Mr. Krabs' Krabby Patty. Although mentioned in previous episodes, chum first physically appears in the episode "Friend or Foe."

Role in series

During Plankton's childhood, he and his former best friend, Mr. Krabs, saw how their classmates' favorite burger joint gained "li-spect" and wealth. Pursuing their own yet combined goals, they attempted to open their own restaurant with their own recipe and burger, which turns out to take no attention. Their burger poisoned Old Man Jenkins, resulting in an argument that sparked their hostile relationship.

Mr. Krabs made his own burger, the Krabby Patty, and Plankton used chum for his burger. Plankton's creation proved foul even to those who could eat anything. On the other hand, Mr. Krabs' tasted quite good.

Plankton continues to use chum in most of his products, despite its foulness and overall toxicity (many have vomited after eating it). In later seasons, his chum was still inedible but another quality in his restaurant, such as the Chum Caverns or a popular slogan, would draw in customers.

In "Krabby Patty Creature Feature", SpongeBob learns that the cure to the Secret Patty's side-effects is actually chum. He then uses it to return everyone back to normal after they mutated into Krabby Patty zombie monsters, which helped him save the day.


The Chum Bucket contains a variety of products that are mostly made out of chum:


According to the episode "Spongicus," it is said that Plankton's chum is made from:

  • Jellyfish Squeezings
  • Seahorse Snout
  • Whale blubber (which is ironic due to Plankton's fear of whales)
  • Sprinkle of anchor rust

According to the episode "Jailbreak!," there is an alternate way to create chum. All that is needed is a toilet and:

  • Cultural fungus growth medium (an old sock)
  • Subtropical vegetal matter (a banana peel)
  • Organic filler (a bucket of trash)
  • Live bacterial culture (a recently used napkin)

After adding all of those, Plankton closes the seat and flushes it, causing them to mix together and create the chum.


  • In real life, chum is inedible for people, which means it is not suitable for eating.
  • According to "The Krabby Kronicle," his chum is actually chum made from real live fish, which serve as the series' characters. Chum should already be meat from fish, as that is how it is in real life.
  • In the later seasons, some characters have gained the habit of eating chum despite tasting horrible to the customers who have already eaten it.
  • Most of the time, the chum bears a reddish-brownish color similar to that of real-life beef patties.
  • Chummy Patties are the only food that Plankton serves that isn't actually made of chum. It is basically a pure grease sandwich.
    • Oddly, they still have "chum" in the name.
  • According to the episode "Friend or Foe," chum is actually an ingredient in the Krabby Patty secret formula.
  • As revealed in "Jailbreak!," chum can actually be used to help pull off crimes and as a result, the criminal community holds Plankton in high regards.
  • Out of all the chum-related food, the Chummy Patties and Chum Fricassee are the only ones that Plankton has sold that actually taste good.
  • In "Free Samples," it is revealed that Patrick Star is the only one who can eat chum compared to anyone else who eats it. Also, in "Chum Caverns," Patrick ate a lot of Plankton's chum, which means he is the only one who loves eating it, though he doesn't know the food item is sold at the Chum Bucket.
  • Despite the fact that the ingredients for chum (as explained by Plankton in the episode "Spongicus") are only just that, chum, many other things have been seen in it such as an eyeball, as seen in the episode "Drive Thru."
  • Pre-cooked chum can be used as a cure to revert the victims who ate Sandy’s Secret Molecular Krabby Patties, transforming those who are Krabby Patty Zombies back to normal in "Krabby Patty Creature Feature."
  • In real life, people use chum for bait when they catch fish.
