Mia is Althea Sol Alfitaria's pet ferret in Final Fantasy Crystal Chronicles: The Crystal Bearers.

Rather troublesome, she seems to have a fondness for treasures, especially the Crystal Idol that Layle obtains from Amidatelion early in the game. Layle pursues the ferret through Alfitaria, and upon catching her and getting the Crystal Idol back, meets Althea for the first time.
