Clara Cluck debuted in 1934 in the Mickey Mouse cartoon Orphan's Benefit. Since then she has appeared as a semi regular character in the Mickey Mouse cartoons. In the comic books she is shown in Duck universe as Daisy Duck's best friend. Clara has been a member of Mickey's original farmyard gang since the beginning of his career, although she is seen less often than Clarabelle Cow and Horace Horsecollar.
Clara's singing is meant to be a caricature of the Bel Canto style of Opera singing popular at the time of her appearance. Some of her arias are clearly modelled on those of Tosca. Her last major appearance was as one of the musicians in Symphony Hour. Curiously, although she is seen in the rehearsal scenes at the beginning, she is not seen in the performance scenes at the end.
