Ash has decided to explore more of Melemele Island and runs into a trainer called Hau, who turns out to be the grandson of Island Kahuna Hala. Hau mentions that he and his partner Dartrix are currently training for the Melemele Island Grand Trial and gets excited when he learns that Ash has already completed it. After seeing Rowlet's evolved form, Ash challenges Hau to a battle, but through an accident he and Rowlet end up losing. Hau agrees to a rematch the next day; can Ash and Rowlet come up with a new move to defeat Dartrix? Meanwhile, an unfortunate attempt to play with a Pyukumuku causes Eevee to meet Pikachu and the Pokémon gang. (Source: Wikipedia)
