In the short film "Meloetta's Moonlight Serenade," Pikachu serves as a central figure in aiding the Mythical Pokémon Meloetta during the annual Moonlight Recital, an event held in the Pokémon Forest when the moon passes over Lunatone Rock. When a sudden sandstorm scatters all but one of the five special Melody Berries needed for the performance, Pikachu takes charge by organizing a search party to recover the lost berries. It rallies numerous other Pokémon to join the effort, coordinating their actions across the forest.

Throughout the mission, Pikachu devises creative solutions to challenges, such as orchestrating a climb atop a group of Drifblim to retrieve a berry from a high location. The successful recovery of all the berries enables Meloetta’s recital to proceed, concluding in a musical celebration. The film showcases a wide array of Pokémon from various regions, including every starter from Generations I through V, with Pikachu consistently leading and motivating the group.
