Kelpo is a cereal that appears throughout many episodes of SpongeBob SquarePants.


Kelpo is packaged in a small, yellow box that depicts an image of a piece of kelp with a face, named Kelpy. The cereal's name is written at the top in blue and in all caps and also says "with one of 8 essential prizes inside!" on an orange burst effect.

Role in Series

Kelpo appears quite frequently in the SpongeBob SquarePants series. A fish tries to pass a box of Kelpo off as SpongeBob in "Prehibernation Week" and SpongeBob is seen eating it in "The Bully" while Flats is punching him. The brand's most prominent featuring is in "Waiting," in which SpongeBob needs to collect 99 box tops from Kelpo boxes before eating all the cereal to obtain a free toy in the mail.

In "Sentimental Sponge," SpongeBob gathers many Kelpy toys due to his obsession over items at that time.

Kelpo also appears in the episode "Larry's Gym", Larry tells SpongeBob to do some crunches, but he takes it literally and crunches on some Kelpo.

  • It can possibly be related or made up of kelp, hence its name and the mascot.
  • In "Karate Choppers," the cereal is shown to contain kelp, however, in other episodes it is shown to be normal ordinary cereal.

  • SpongeBob seems to have a whole collection of Kelpo toys, as seen in "Sentimental Sponge," where he is shown gathering plenty of Kelpy toys due to his obsession over items during that time.
  • In SpongeBob's Director's Commentary for the level "Paparazzi Patrick!," SpongeBob says that Patrick's final project for photography class was a framed photograph of a box of Kelpo cereal.
  • A cereal with the same name is seen on Patrick's breakfast table in "Rock-a-Bye Bivalve," but the box differs in appearance from its usual featuring and doesn't depict the brand's mascot, Kelpy.
  • On the box it says you can get one of 8 essential prizes inside, but in "Sentimental Sponge", SpongeBob only has one type of prize in his collection.
    • This is likely just a variant rather than a different brand, as the manufactuers would get involved with a plagiarism lawsuit if that were the case.
