Blanche Ramora and her sister Coral belong to the sister-act synchronized swimming duo: The Aquadolls. They have always been the chief rivals of the Darling Mermaid Darlings. Blanche was married to Shane Trickle. She was killed in a shark accident.
She appears in the series finale of Pushing Daisies, "Kerplunk". Her surname is presumably designed to evoke 'remora'.
