Pikachu's PikaBoo

Pikachu and his Pokémon friends are playing on the beach when they notice a mansion nearby. Curious, they wander onto the grounds, looking for something new to do. There, they meet Yogiras, a stern Pokémon who keeps the mansion and its garden in strict order. Despite Yogiras' grumbling, his own friends and Pikachu's group ignore his protests and start a lively game of hide-and-seek. Frustrated at being brushed aside, Yogiras kicks a rock-only for it to strike a lawnmower, turning it on. The machine starts racing wildly after the Pokémon, putting everyone at risk. Now, Pikachu, Yogiras, and all their friends must work together to stop the runaway lawnmower and protect each other.
