The Cookie Carnival

In this confectionery-themed Cinderella-story, a sad Sugar Cookie Girl is turned into the Queen of the Cookie Carnival (aka, Miss Muffin) by a wandering Hobo Cookie. The short’s an homage to the Atlantic City boardwalk and its “bathing beauty” contest—which eventually became the Miss America pageant—of the 1920s and 1930s.
