Emergency Mother-In-Law Program (E.M.I.L.P.) is Karen's mother and only appears when Karen short circuits.
E.M.I.L.P. was programmed to be a mother-in-law program, and it made an appearance in "Single Cell Anniversary." She doesn't like the idea of Plankton being the husband of Karen, saying she could have been with an ATM. She hasn't appeared again. Plankton mentions her and her husband in "The Algae's Always Greener," when he said, "Your parents must have been like, part computer or something." She's voiced by the same person who voices Karen.
PLANKTON, WHAT HAVE YOU DONE TO MY DAUGHTER? YOU MADE HER CRY. YOU KNOW, SHE COULD'VE BEEN WITH AN ATM, SOMEONE WITH MONEY, BUT SHE CHOSE YOU!, I DON'T KNOW WHY!!!!
In the Indonesian version, this character has the name: P.D.I.M. (Program Darurat Ibu Mertua) from English translation.
