The Queen of the Manatees is, as her title suggests, queen of the manatees and Mermando's fiancée.
In "Society of the Blind Eye," Mermando explains to Mabel in a bottled message that he has pledged to marry her as a means of avoiding an undersea civil war, though it remains undisclosed as to whether or not she was forced to go through with the marriage as well.
She is a rather large manatee with light gray skin. She wears a pink dress with white buttons and white frills on the sleeves and collar. She also wears a large red and gold crown with spotted fur trim at the bottom, green jewels above it and a purple diamond on top.
Despite her being a manatee, Mabel believes that the queen is very beautiful.
