Set in a world in which guinea pigs have turned into cars, there live “molcars” - a portmanteau of the Japanese word for guinea pig (morumotto, from the word “marmot”) and “car.” They are fluffy and adorable with big round eyes, cute little tire feet, and big round butts. Each is full of personality and energy as they speed around town rescuing animals, taking part in high-speed chases, and more, and this time, Potato and his molcar friends are heading to driving school!
