Tex Avery introduced a new character in his cartoon short Egghead Rides Again, released July 17, 1937. Egghead initially was depicted as having a bulbous nose, funny/eccentric clothing, a voice like Joe Penner (provided either by radio mimic Danny Webb or actor Cliff Nazarro) and an egg-shaped head. Many cartoon historians believe that Egghead evolved into Elmer over a period of a couple of years. However, animation historian Michael Barrier asserts, "The Egghead-Elmer story is actually a little messy, my sense being that most of the people involved, whether they were making the films or publicizing them, not only had trouble telling the characters apart but had no idea why they should bother trying. " Egghead made his second appearance in 1937's Little Red Walking Hood and then in 1938 teamed with Warner Bros. ' newest cartoon star Daffy Duck in Daffy Duck and Egghead. Egghead continued to make appearances in the Warner cartoons in 1938, such as in The Isle of Pingo Pongo and A-Lad-In Bagdad. In A Feud There Was (1938), Egghead made his entrance riding a motor scooter with the words "Elmer Fudd, Peacemaker" displayed on the side, the first onscreen use of that name. Egghead shifts from having a Moe Howard haircut to being bald, and wears a brown derby, a baggy suit, and a high-collared shirt. Egghead returned decades later in the compilation film Daffy Duck's Quackbusters. More recently, he also made a cameo appearance at the end of Looney Tunes: Back in Action and was also given in his own story, which starred him alongside Pete Puma, in the Looney Tunes comic book.
