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 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.
