List of characters

Billy Bob Plankton, is one of Sheldon J. Plankton's cousins. He is a hillbilly like the rest of Plankton's cousins. His only appears in "Plankton's Army."


He is a rectangular plankton. He has one eye and a Gray mustache. He is one of the few family members not to have antennae. He is in a wheelbarrow with a blue blanket. It is unknown why, the most likely reason is that he cannot walk.


He came to the Chum Bucket after receiving one of Sheldon's numerous calling for the family's assistance. Once he entered the Chum Bucket, he was granted root beer if he and the rest of the family helped Sheldon steal the Krabby Patty Secret Formula. He later assisted him to find out that the "secret ingredient" was mashed plankton.
