Creation and development

Originally, in "Spy Buddies," instead of Plankton finding SpongeBob and Patrick when they fall into the Chum Bucket, SpongeBob and Patrick were going to find a domestic dispute between Plankton and Karen, which featured Plankton not wanting to go to Karen's Mother-in-law's house because she was going to be a car alarm that was going have only said, "Stay away from the vehicle."[1] It should be noted that "Karen's Mother-in-law" may have been a mistake and that the commentator was referring to Karen's Mother, whom would later become, "E.M.I.L.P." However, this has not been confirmed.
