Pokémon Horizons

Navi is really depressed due to losing the Dream Ball. It was really dear to her, as she had been given it by Matiere so that she'd one day use it to catch hold of her dream... Meanwhile, Metamon picks up the Dream Ball Navi dropped on the airship and decides to head off to Miare City all by itself in order to return it to her...! Will Metamon be able to find Navi and return the Dream Ball safe and sound?!
