NancyO'Malley (or better known as Officer Nancy) is a blonde-haired, purple fish. She works as a police officer in Bikini Bottom with other officers. She appears to be quite dimwitted.
She and her partner, usually Officer John, had a large role in "Nasty Patty." In this episode, Mr. Krabs gave her a soda but forgot to give her ice, Then, when she hit the Health Inspector in the head with a barrel, her first name is revealed. When she arrested SpongeBob for not inviting her to his party in "Party Pooper Pants," her last name is also revealed. Nancy's 6 partners are Officer John, Officer Rob, a yellow one, a purple one (males), a female green officer with orange curly hair (appeared only in the ending of "No Free Rides" and "Goo Goo Gas"), and her twin sister Marcie, who only appears in "Patty Caper." She looks just like Nancy except that she is green and has red hair. SpongeBob called her to arrest the Tattletale Strangler (unfortunately, the Strangler escaped again). She was happy when SpongeBob "put" the Strangler in jail (the strangler did it by himself and was with Patrick).
