Because of a charming evolutionary twist, guinea pigs have transformed into plush motor vehicles called "Molcars." Drivers now experience a velvety cabin while meeting all their travel demands. Yet Molcars are not merely lettuce‑powered engines; they possess consciousness, harboring personal concerns and aspirations. Whether beside their owners or interacting with one another, these wheeled rodents find themselves in countless thrilling and unpredictable escapades—adventures that only a Molcar could encounter in the bustling city streets during their daily commutes and adventures.
