Plankton's cousins

Doug Plankton is one of Plankton's cousins. He is a hillbilly like the rest of Plankton's cousins. He only appeared in Plankton's Army, and at the end of the episode ran away upon learning that an ingredient to the Krabby Patty was ground plankton (This was later revealed to be a trick by Mr Krabs.), like all of Plankton's other cousins.


  • The name could be reference to the first name of Plankton's voice actor, Doug Lawrence.
