S22E20 Kangaroo Christmas

Thomas finds himself in Australia for the Christmas holiday and feels let down by the lack of snow, as it contrasts sharply with the winter wonderland of Sodor. However, his adventure takes a turn when he meets a young girl named Madeleine, who needs his assistance in rescuing her toy kangaroo from a wild one. Thomas embarks on this unexpected mission, discovering the joys of an Australian Christmas while helping Madeleine in the process.
