It’s a bright summer day, and everyone is brimming with energy. Pikachu and his friends play with a beach ball. While chasing each other and diving into a river, Pikachu and Pochama drift over a sprawling metropolis. “Where are we?” they ask, scanning from the rooftops. Suddenly, a bang erupts as jagged‑eared Pichu collides with Muchul. The two erupt into an angry argument: “The Sparkling is gone! It was the present we were supposed to give to Kireihana.” To make matters worse, today is Kireihana’s birthday! Realizing they must hurry and search, they learn that the Nyarth‑tachi are also after it. Thus, the Great Sparkling Search begins.
