Pokemon: Mezase Pokemon Master EP8 - Getting to the Heart of it All!

Ash, Misty, and Brock arrive in a town where heart-shaped objects are being taken from the town's residents by a Banette. The group discovers that Banette's motive for taking the items is because it used to wear a heart-shaped hair tie, which was gifted to it by its long-lost owner many years prior. Ash and his friends manage to reunite Banette with its owner, which turns out to be the local Nurse Joy.
