Madame D'Oinkeau is a pig that was, at one point, Dimitri Lousteau's fiancée. She lives in a mansion in Monaco.


Little is known of D'Oinkeau, though it is known that she owned the Venus de Whalo, a valuable statue that she offered to Dimitri as an engagement gift. The statue was stolen by the Cooper Gang at the engagement party.

Dimitri was only engaged to her in an attempt to steal her wealth.
