The scenario is set in a world where guinea pigs have evolved into automobiles. "Molcar," the car that relaxes you. They always explore the world with their naive looks, having huge wide eyes, a curvaceous butt, and quick limbs. Even in traffic, simply glancing at the butt of the Molcar in front of you might make you feel better. Even if they cause mischief, their fuzzy sweetness will make you forgive them!? It's a Mol-animation loaded with cure, friendship, adventure, and furry acts, surrounded by scenarios only met by automobiles!
