A comedy movie, MOLMAX (Zoku-hen) picks up where the first MOLMAX film left off. In that earlier movie, high-tech Molcars guided by artificial intelligence arrived in Molcity, and Potato and his friends were caught up in a pursuit between a secretive group and an AI called Canon. Molcars are guinea pigs transformed into vehicles, soft and wide-eyed with tiny tire feet, and each one bursts with character and pep.
