Blurb
As the Twinleaf Festival winds down, our heroes encounter a Natu and a Xatu, who provide them with a mysterious and puzzling adventure they’ll never forget!

Coming to the close of the Twinleaf Festival, our heroes are enjoying some of the many treats it offers when they run into their old friend Barry, who challenges Ash to a battle right away. But Barry suddenly notices a Xatu overhead and takes off, with Ash and Misty following.

Soon everyone (minus a very bored Brock, who has volunteered to man one of the booths to cover for a sick attendant) comes across a strange circus tent, and they’re all invited inside. Suddenly, a blinding light causes Ash and his friends to lose consciousness. Upon awakening, they realize they’ve become separated from one another, and they’re surrounded by seemingly gigantic Pokémon!

Meanwhile, Team Rocket is manning the Goldeen Scoop Game booth at the festival, and a stranger threatens to win every Goldeen in stock! But James comes to the rescue, as his younger years’ training in the Goldeen Scoop Game allows him to defeat the stranger and keep the Goldeen for other customers.

When our heroes are finally reunited, they begin to think that the mysterious Natu might hold some answers to their strange experiences of late. After defeating a gigantic Camerupt, they all find themselves back to normal size. They run into Barry’s dad, Palmer, who attempts to explain some of the mysteries of the past, present, and future, although Barry is more confused than ever. We leave our heroes as they ponder the fascinating things Palmer has told them!
