Nat[5] Tucker[6] Peterson[7] is a yellow-tan fish who has appeared in various episodes and is one of the most common fish characters in the series. He first appears in the episode "Ripped Pants" and plays his biggest role yet in "Plankton's Regular."


He is a yellow-tan-colored fish with light lavender lips and a dark lavender dorsal fin. He has light green arms and legs and wears faded light blue shorts. His stomach is dark-yellow/green and he is very slender and skinny. He often goes without wearing a shirt or shoes.


Nat works at Snail Po Headquarters and a variety of other places. He was also a member of the Bikini Bottom Music Lovers Club. His last name is revealed in the episode "Missing Identity" when Norma Rechid addresses him by the surname "Peterson." He is friends with Fred, Harold, and DoodlePants (as seen in Drawn to Life: SpongeBob SquarePants Edition). He tells DoodlePants helpful advice on how to defeat DoodleBob.

He seems to be with Martha Smith in various episodes, although Shubie may also be his girlfriend/wife, as seen in the episode "SpongeHenge."

In "Plankton's Regular”, his most notable appearance, he feigns enjoyment of Plankton's chum in order to fulfill a deal with Karen, Plankton's wife. He is shown to live in a mobile home and apparently possesses great acting skills, as he manages to fend off SpongeBob's persistent attempts to give him a Krabby Patty. However, one can foresee the ending when Nat is forced to taste Mr. Krabs' Krusty Chum and he proclaims that it is the second foulest thing he has ever tasted. The audience can infer that the foulest thing is actually Plankton's chum, and Mr. Krabs has thwarted him in that area of food service as well.

At the end of the episode, Nat breaks the news to Plankton and cuts off the deal with Karen, returning the money that she had given him to eat at the Chum Bucket. He is last shown being carted off by medical staff members, which he claims will be the third time he will have visited the doctor on account of Plankton's chum.

In the episode "Squid Baby," he yells, "My face! And also my leg. But mostly my face!," making a reference to Fred's catchphrase "My leg!"
