This is the page about Plankton's cousin. For other uses, see Marvin (disambiguation).
Character
Marvin is one of Plankton's cousins. He appears in the short "Plankton. A Thank You Would Be Nice."
Description[]
Marvin appears to be a much more primitive species of plankton. Marvin is notably smaller than some of Sheldon's other cousins.
Role in short[]
Cousin Marvin appears when Plankton is explaining how his species are the most important living creatures on the planet. He uses cousin Marvin, who he describes as stupid, as an example, but he then explains how Marvin has planktonic plant brains that make up half of the Earth's oxygen.
