|“||Hey look, everybody! It's Cousin Plankton!||”|
— Clem, "Plankton's Army"
He is a light green plankton with an overbite and messy teeth. He has a light yellow eye and wears a messy, light blue hat made out of rags.
Role in series
He is contacted by his cousin Sheldon J. Plankton, who needs his family's help to obtain Krabby Patty secret formula. He is introduced as the leader of the rest of Plankton's cousins, since he does most of the speaking. Clem re-introduces Sheldon to his family, when he seems unfamiliar with them. But after going on and on introducing the hundreds of the family members, Plankton screams at him to stop.
"One Coarse Meal"
He appears in Plankton's flashback about his family being eaten, and then appears again inside Pearl during Plankton's nightmare.
- He was the character who revealed Plankton's first name.
- Unlike the rest of his family, he cannot read.
- In the episode "Plankton's Army," he was voiced by Dee Bradley Baker, but in the video game Plankton's Robotic Revenge, he was voiced by Bill Fagerbakke instead.
