They find the missing Tepig trapped inside of Rockridge Fort's cannon, and fire him out of the cannon at Snivy's suggestion. Pikachu, Oshawott, and Snivy go to the Crag Area, where they find Victini looking for his friend, Tepig. The trio also find Piplup, who stays behind in Wish Park to warn anyone else who comes into the park. She allows them to ring the Wish Bell, warning them of the consequences if they continue to interfere. The trio complete Chandelure's attraction, Dance Inferno, then meet the second-in-command of Wish Park: Gothitelle. There, they find Zoroark, who had been bringing Pokémon into Wish Park, but went back to rescue them after they didn't come back. With Snivy's help, the team finds the missing piece of the poster and reopens the portal to Wish Park. They find the Poster hiding Windmill Way's portal to Wish Park to be ripped, and find a Zorua looking for his friend, Zoroark.
They proceed to the Arbor Area, where they meet Snivy, a tomboyish princess who wants adventure and hates her royal duties. After fighting Cofagrigus, they ring the Wish Bell in the Cake Zone, freeing all Pokémon who were trapped there. They enter Wish Park and defeat Cofagrigus' attraction, Cake Contraption. They learn from him that to open a portal to Wish Park, they must simply wish for it to open, and that making more friends to help wish for the portal to open causes it to become a lot easier. Pikachu and Oshawott decide to team up and solve the case of Wish Park, starting by finding Krokorok in Cove Town. The three are then chased out of Wish Park by two floating hands, which end up trapping Piplup in Wish Park. The two are almost trapped in Wish Park, but an Oshawott investigating Pokémon disappearances comes to their rescue. However, they soon find that Pokémon who play the attractions in Wish Park for too long become trapped and unable to leave. They meet Krokorok and Sandile, who take them to Wish Park, which is spoken as a place where fun never stops. Pikachu and Piplup come to a new PokéPark to play together in Seasong Beach, in the Cove Area. Reshiram is optimistic, stating that he sees a light in the darkness. Zekrom expresses concern, and warns of trying times for PokéPark. The game opens with Reshiram and Zekrom conversing.
