Mrs. Squiggles is a yellow worm that wears an orange wig. She wears earrings, eye shadow, and lipstick.
She is owned by a fancy blue fish with black hair and a black suit on. Mrs. Squiggles had orange hair on her head that the blue fish made just for her. However, when Gary told the other pets to start a pet riot, Mrs. Squiggles put her orange wing on the blue fish's black smooth hair as the blue fish screams as payback. She is yellow with orange hair and a collar.
In "Plankton's Pet," she appears at the Animal Shelter meaning that either her owner got her after Plankton got Spot or her owner released her to them sometime after the Pet Show.
