Nat[1] Peterson[2] (Mr. Plankton Universe) is a customer from the Krusty Krab and only appeared in the episode "The Algae's Always Greener."


He ordered two deluxe Krabby Patties when Plankton tried to take them for 'Bun Inspection'. Alternate Universe SpongeBob said those patties were for the customer so Plankton said he'd boil Alternate Nat in hot oil and rip out one of his body parts until SpongeBob signaled that he was sitting right there. Alternate SpongeBob provided two other patties. Later, Alternate Nat showed Plankton a disgusting Krabby Patty, consisting of an eyeball and a dirty sock, among other things. Alternate Nat asked if this was "where he got his sick kicks" and Plankton blamed Alternate Squidward because he was the new fry cook.
