Pokemon Diamond & Pearl Atsumare! Pokemon Hoshi Matsuri

Ash, Dawn, and Brock join a lively Pokémon Star Festival filled with quizzes, games, and stargazing. The celebration feels harmless at first, even if its suspicious hosts seem strangely familiar.

Then Pokémon begin vanishing one after another, and Pikachu disappears as well. The cheerful night turns into a rescue mission as Ash races to uncover what is really happening behind the festival.
