Kelp Chips are chips sold in Bikini Bottom. They only appear in the episode "The Inside Job." In that episode Plankton eats them while watching TV in the Chum Bucket.
The wrapper of the Kelp Chips is blue. On the front there is an dark green circle and yellow letters says 'Kelp Chips'. The bag closely resembles Lays Potato Chips, and some unheard of brands of potato chips, such as Golden Flake Potato Chips.
