Ash, Dawn, and Brock finally arrive in Eterna City. They head to the museum where the rare Adamant Orb has been stolen by thieves. They soon run into both Gardenia and Nando. Since the thieves used a Sunflora to help rob the museum, they believe Nando and his new Sunflora are the thieves. Ash, Dawn, and Brock send out their Pokémon to try and catch the real thieves, and they even have help from Viridian City's Officer Jenny. The poilce officers then begin their search for Nando's Sunflora, who has just run into Pikachu and Piplup. Meanwhile, Team Rocket, who are the real thieves, hideout is a small room since the entire museum is sealed off, but they are soon found by Pikachu, Piplup, and Sunflora.
