Norma's daughter is a blue fish who makes several cameo appearances throughout the series. She first appears in the episode "Valentine's Day."
Norma's daughter is light blue with faded blue lips and wears a light purple dress with matching leg bands.
Norma's daughter's father is Tom as revealed in "Bubble Buddy", but it is currently unknown who her mother is. Her mother is most likely Tom's ex-wife, Nancy Suzy Fish, who appears with her and Tom in "Bubble Buddy."
Most of the time, she only appears very briefly or in the background. In "Mid-Life Crustacean," she is seen playing with a ball with some other kids. In "Kenny the Cat," she is one of the fish who tries to breathe underwater like Kenny the Cat.
