Thanks to an enchanting evolutionary anomaly, guinea pigs have transformed into plush cars affectionately called "Molcars." Drivers can luxuriate in the snug interiors of their fluffy vehicles while meeting all their transportation needs. However, Molcars are not mechanized automobiles powered by lettuce; they are living creatures with their own worries and desires. Whether alone with their operators or among other Molcars, these rodent-on-wheels become embroiled in countless daring and exhilarating escapades that are unique to Molcars.
