White Snorlax begins as a snow sculpture meticulously crafted by Pikachu and other Pokémon near a winter Pokémon Center. At night, the snow figure spontaneously animates, gaining sentience and mobility. It approaches the cabin window where the Pokémon rest, beckoning them to follow.

This living snow Snorlax leads Pikachu and companions on a nocturnal trek to a cliffside fruit tree. Attempting to retrieve an apple, the structure collapses under its weight. The group lands on Snorlax's belly, using it as an improvised sled. They drift on ice into the ocean, encounter a whirlpool, and observe aquatic Pokémon. Snorlax uses a Blizzard ability to freeze the whirlpool, creating a stable ice platform. Later, it helps form an ice boat alongside other Pokémon.

After the boat disintegrates, Lapras rescues the group, transporting them to a glacial area populated by identical snow Snorlax figures. Here, the animated Snorlax departs to join the others. Pikachu and friends awaken the next morning beside their intact snow sculpture, leaving the nocturnal events ambiguous. The character displays no connection to standard Snorlax biology or behavior beyond visual resemblance. Its narrative remains confined to this self-contained story.
