Kelpo is a brand of cereal that appears in many episodes, beginning with "Karate Choppers."


It is packaged in a small, light 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 dark blue, capitalized text, and also reads "with one of 8 essential prizes inside!" on an orange burst effect. There are squiggly lines on the side of the box, along with a blue square.

The cereal itself is average pale yellow chunks.
