Kelpo is a cereal that SpongeBob eats in the beginning of the episode Shanghaied. It appears frequently in the SpongeBob SquarePants series . The brand's most prominent featuring was in Waiting, when SpongeBob needed to collect 99 box tops from Kelpo boxes to obtain a free toy in the mail. It is most likely a parody on Cheerios.
Kelpo resembles a small, yellow box. There is also an image of a kelp with a face (mostly likely Kelpo itself). The word "Kelpo" is also written at the top in blue.
