Pikachu's Great Sparking Search!

Summer fun turns into a quest when Pikachu and Pochama, playing with a beach ball, drift down a river and arrive in a sprawling metropolis. Exploring the city's rooftops, they stumble upon a conflict between a jagged-eared Pichu and Muchul. The pair are upset; they lost a "Sparkling" present intended for Kireihana, whose birthday is today. The loss is a major problem! With the clock ticking, Pikachu and friends join the search for the missing Sparkling. However, they aren't alone in their pursuit. The ever-present Nyarth-tachi (Team Rocket) are also aiming to find the Sparkling. The Great Sparkling Search begins, promising a race against time and a clash of intentions amidst the urban landscape.
