Molly is a yellow steam tender engine. Emily laughed at her for hauling "empties" freight cars, which hurt Molly's feelings, so Thomas came up with an idea. He had workmen decorate Molly's trucks with lanterns and cover them with tarpaulins, to make them look special to the other engines. The wind, however, blew off the covers in front of Gordon, Percy and Emily. Molly ran away, embarrassed, until she learned that engines at the depot needed her trucks to carry coal. When Molly arrived at the depot, Henry, Edward and James were grateful to see her.
