In the mid-1930s, Allman appeared in cartoons for producer Leon Schlesinger, released through Warner Bros. She can be heard in the first Porky Pig cartoon "I Haven't Got a Hat" in 1935. She may have originated the character of Clarabelle Cow prior to this, but there are no records indicating the specific cartoons in which she voiced Clarabelle, who was featured in 28 Disney cartoons from 1928 to 1942. In 1937 Allman voiced the title role in the cartoon "Little Red Walking Hood", a spoof of Little Red Riding Hood. Allman married sports promoter C. C. Pyle on July 3, 1937 and was with him when he died on February 3, 1939.
