The story of Claymates begins when a scientist creates a formula that transforms clay into living animals. A Witch Doctor desires the formula for himself, capturing the scientist, and transforming the scientist's son Clayton into a blue ball of clay. As Clayton, the player must travel across the world, from his backyard to Japan and beyond, in order to rescue his father and return to normal.
