|“||He is not a monster!||„|
|~ Lucille defending Francoeur|
Lucille is a Parisian girl and singer with red hair and green eyes. She is dressed all in white with fake wings behind her back on stage. She argues a lot with Raoul, a childhood friend, but is the first to accept Francoeur as he is and will do anything to protect him.
She is married off to the conceited Commissioner Maynott by her aunt Carlotta, who has raised her since her parents passed away.
She is looking for a musician for her show and one night discovers a giant flea. At first Lucille is scared of him, but then, hearing his singing, she discovers how lonely he is and takes him into her home. Lucille names the giant creature Francoeur and disguises him so the police won't discover him, unaware that the flea has grown because of magic fertilizer.
She is willing to give up her freedom to save Francoeur and in a show unexpectedly reveals his identity. In a battle on the Eiffel Tower, Lucille stands up to protect her friends, but Francoeur is shrunk back down to size from the snow. Maynott, who tries to kill Francoeur, is arrested for treason.
Lucille is distraught after the "death" of Francoeur, but on stage, the flea is perched on her earring, and Raoul and Emile bring him back to human size via a new concoction.
