Fifi is one of the girls who was trapped with Madeline in LaCroque's lacemaking business in Madeline: Lost in Paris. She was presumably sick (due to coughing several times in the movie), and her hair was cut to make lace. When LaCroque's scheme is discovered, Madeline, Fifi, and the other girls are rescued. Madeline spends the reward money to build a school for Fifi and the girls to live in. After receiving treatment, Fifi's coughing stops and her hair is back to normal.
