Emergency Mother-In-Law Program (E.M.I.L.P.) is Karen Plankton's mother who appears in the episode "Single Cell Anniversary." She scolds Plankton for making Karen cry after he sings her a romantic love song as her anniversary gift. She hates Plankton and wishes Karen had married an ATM machine.
She is a computer who is similar to her daughter. She makes an angry face when seen and has light green glasses, a light green nose, and a light mouth.
Plankton indirectly mentions her and her husband when he says, "Your parents must have been like, part computer or something."
"Single Cell Anniversary"
It is Karen and Plankton's anniversary. Karen has accessed the Krabby Patty secret formula and is willing to give it to Plankton if he gives her something. Plankton leaves.
Later, SpongeBob notices that Plankton needs help and agrees to help him think of something for Karen. Soon, they find out that she is a music lover. SpongeBob teaches Plankton how to sing. Later, Plankton sings a love song for Karen with the help of SpongeBob and Patrick. As promised, she starts downloading the Krabby Patty formula. However, she starts crying, which she is not supposed to be able to do, and she short circuits.
She turns on again, but instead of showing Karen it shows "E.M.I.L.P." Plankton asks what that is and the full title shows up as, "Emergency Mother-In-Law Program." His mother-in-law then shows up on the screen and complains about Plankton.
