is a 1980 American animated mystery comedy film produced by United Feature Syndicate and distributed by Paramount Pictures, directed by Bill Melendez and Phil Roman.

At Charlie Brown’s school, Linus Van Pelt introduces two French exchange students, Babette and Jacques, to his class.

However, Marcie, who has been studying French, translates the letter and explains that Charlie Brown has been invited to stay at the Château du Mal Voisin (House of the Bad Neighbor).

Upon reaching their respective destinations, Peppermint Patty and Marcie are welcomed at a farm in Morville-sur-Andelle owned by a boy named Pierre, who immediately captures their attention.

Charlie Brown rushes to seek help from Peppermint Patty and Marcie, while Pierre alerts the fire department.

He, along with Snoopy, Woodstock, Linus, Peppermint Patty, and Marcie, departs to explore more of the French countryside before ultimately returning home to the U.S. Schulz stated that he conceived the idea for the story while visiting the Manoir de Malvoisine in Le Héron, a location where he had been briefly stationed as a soldier during World War II.
