Eugene H. Krabs upon seeing Plankton's cousins formed as an army, "Plankton's Army"

Plankton's cousins are part of Plankton's family that appear in the episodes "Plankton's Army, "One Coarse Meal," and "Karen's Virus," as well as the games Delivery Dilemma, Sea Stampede, Creature from the Krusty Krab, and Plankton's Robotic Revenge.


They dress and act in the manner of a modern hillbilly. The majority of them can read except for Clem.

Unlike Plankton, they are not evil. However, they're perfectly fine with doing Plankton's evil bidding as long as he provides them with various rewards, such as memory for their laptops, an extra string for a banjo, matching boots, and most importantly for root beer (which seems to be their favorite beverage).
