Bozly's Father's Chansey lives at a Safari Zone. After its partner died, it stayed there and helped out by healing injured Pokémon. It kept the hat that its partner used to wear and wore it on its head.
Bozly spent years trying to get his father's hat from it.
Bozly put up a wanted poster in the Safari Zone to catch Lucky but no one was able to catch it.
Meg was curious about the relationship between Lucky and her uncle, so she decided to venture into the Safari Zone alone to find it. She found out that the Lucky had been helping her uncle all these years in the Safari Zone and he finally realized that with
Meg's help. He apologized to Lucky and it returned the hat to him.
