Molly, Mop and Moppet land their Magic Adventure Machine in Paris, France. While Molly wishes to meet a Parisian Ballerina, Mop hopes he gets a chance to eat croissants with jam. Upon meeting Molly's cousin, Pierre, in a French garden, the team quickly learn that Pierre has lost his grandfather's Parisian music box somewhere in the city. The team depart on an adventure to retrieve the handmade family treasure. They first visit the Louvre, where they look for Mademoiselle Mona Lisa, but are left disappointed to not find the box. The team then meet Napoleon Bonaparte, who takes them for a ride on his military horse to visit the Arc de Triomphe. While they ride down the Champs Elysees, Molly almost falls off the horse while staring at all the beautiful shops. Napoleon hands Molly a small key to help the team solve their mystery, then he drops them off at Notre Dame. While inside the famous church Moppet finds a beautiful box, but unfortunately, it does not play music. Then a gargoyle taps Mop on the shoulder and suggests he should visit the artists of Montmartre. They walk up the steps of Montmartre and stumble across a red windmill called the Moulin Rouge. When a doorman rudely says 'No Entry!', the team takes a can-can lesson on the balcony with the ladies. Pierre then leads the team to the Artist's Square, where Moppet takes painting lessons with Renoir and tries to paint a picture of Mop. Molly and Pierre speak with Monet, who paints them a map with directions to a music box he once heard playing. But as the team gets lost following Monet's directions, they end up at a beautiful basilica called Sacre Coeur. The team then meet a lady called Marie Antoinette and together they eat cake and many other delicious French cuisines. They then meet Mademoiselle Coco Chanel who makes couture tutus for the whole team. Then they stumble across a French Mime in Sorbonne who informs them that they should visit the Luxembourg gardens. The team finally makes it to the Eiffel tower where they find Pierre's Parisian music box sitting at the top of the tower. They open it using Napoleon's key and inside they find Molly's ballerina. And the whole team celebrates eating croissants and jam at the top of the tower.
