List of characters

William James Plankton, more commonly known as Billy Jim, is one of Plankton's cousins. He is a hilbilly like the rest of Plankton's Cousins. His only appearance was in Plankton's Army.


He is an aquamarine plankton. He has three things that might be antennae that connect to a flap on his back that is darker than the rest of him. He has one eye. He also plays that violin.


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.
