Mrs. Squiggles is a yellow worm that wears an orange wig. She wears light blue earrings, light blue eye shadow, pink lipstick, and a black collar.
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.
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.
