Her fur is purple and white and she keeps a ribbon tied to her hair which causes it to fall over one eye. She has a massive tail, nearly twice the size of her own body, which is the source of her purple coloured stench that stinks of moldy cheese and rotten fish. Fifi lives alone in an abandoned pink Cadillac at the Acme junkyard where she can be found lounging on her bed, listening to music, reading romance novels. Fifi is French and very flirtatious. She speaks English with some French words.
