The Millennium Comet is about to make its long-awaited reappearance in the sky, supposedly granting the wishes of all who see it. Ash and friends are equally interested in the Millennium Festival, especially when they attend a magic performance by the Great Butler. Even more interesting is Butler’s mysterious cocoon, from which Max hears a strange voice calling! When Jirachi emerges from its slumber, Max has a new friend, but only for the few days of the comet’s visit. Meanwhile, Butler wants to revive the Legendary Groudon, and Jirachi just might be able to grant that wish. Can Max, Ash, May, and Brock stop Butler and save Jirachi?
