When Stu Pickles's Reptar invention for the Reptarland amusement park in Paris breaks, he is summoned over to fix it. From the moment Stu and the entire Rugrats crew arrive, life in the French capital is turned upside down. Coco LaBouche, the sneaky head of Reptarland, has an agenda all of her own and is busy scheming with Angelica's help. Chas wants a new wife and Chuckie wants a new mum, but surely Coco is not the right person. Luckily the babies are on hand to sort things out...in their own special way.
