Pokémon S08E10 - Where's Armaldo?

Arriving on an island, Max encounters a Cradily, an ancient Pokémon that is supposed to be extinct. His friends do not believe him, so Max goes away to search for it and finds a building. Ash, May and Brock eventually find a woman and are surprised to see the Cradily Max spoke about. They go to the lab, where they also find an Anorith, which evolves into an Armaldo. Team Rocket barges in and after failing to catch Armaldo, Armaldo goes on a rampage.
