Pikachu serves as a central figure among Pokémon companions Piplup, Buneary, Chimchar, and Ambipom during beach activities. He swims underwater and plays with a Master Ball-like beach ball, displaying curiosity and enjoyment in group interactions.

After Team Rocket's Pokémon cause a disruption, Pikachu and the group become separated from their trainers and transported to a frozen environment. There, Pikachu takes initiative by climbing an icy peak to survey their location. He organizes efforts to return home, following guidance from local Pokémon Spheal and Snorunt toward an ice castle.

Inside the castle, Pikachu observes a conflict between Abomasnow and Froslass over damaged ice statues. He coordinates the group to mediate: Buneary uses Ice Beam and Turtwig employs Razor Leaf to repair the statues, facilitating cooperative problem-solving.

When Croagunk accidentally destroys the newly repaired statues, Pikachu initiates a collective effort to carve replacement sculptures into a mountainside. He guides the Pokémon to utilize their individual abilities and attacks for this task, showcasing leadership and adaptability.

To depart the frozen isle, Pikachu collaborates in constructing an ice boat. This solution enables the group to navigate back to their original beach location, concluding their adventure through cooperative effort.
