Pokémon S15E39 - Expedition to Onix Island!

While training for the World Tournament in Undella Town, Dawn suggests that Ash & Co. need to relax so they travel to a nearby island where many Onix dwell. However, as they explore the island, they inadvertantly anger the Onix that dwell there and the gang gets separated. As they try to find eachother, they keep getting attacked. Meloetta gets angry at Ash getting attacked and manages to change form. Will Meloetta help stop the Onix attack and will Ash & Co. find eachother?
