Officer Jenny asked Iris and Christie to watch after Mimi's Audino after many other Audino began to disappear in the town. Mimi was concerned that her Audino would be the next to disappear. However, Christie and Iris assured her that they had everything under control and put a tracking device on her Audino. Her worst fears came true when Audino began to act strangely and left her side.
After the case was solved, it is assumed that Mimi got her Audino back safe and sound.
Mimi's Audino was suspected to be the next victim of the Audino disappearance case. Iris and Christie watched after it and put a tracking device on it so that even if it ran away, they would be able to follow it. Soon Audino began acting strangely and left Mimi. It joined up with two other Audino and traveled to Team Rocket's secret base all while trying to throw Ash and his friends off their trail. After Roggenrola used Stone Edge on the sound wave machine, Audino joined forces with the other Audino that Team Rocket lured and sent them running with a barrage of different moves.
