In late 1941, after Tex Avery left, he was replaced as the unit director by Bob Clampett. Scribner turned out to be arguably Clampett's best animator. Clampett classics such as A Tale of Two Kitties (1942), Coal Black and de Sebben Dwarfs (1943), Falling Hare (1943), and The Great Piggy Bank Robbery (1946) showcase some of his greatest work: his trademark "Lichty style" of animation. Clampett left Warner Bros. in 1945 to pursue a career in puppetry and television. Not much is known about where Scribner was between 1946-1949 (although he does some animation on two McKimson cartoons starring Porky and Daffy in 1947). In 1950, Scribner returned to Warner Bros. under Robert McKimson's unit. His animation was tamed down to McKimson's standards, but he still got away with wild scenes, like in Hillbilly Hare (1950), Hoppy Go Lucky (1952) and Of Rice and Hen (1953). He left Warners in 1954 and worked at UPA. In his later years, Scribner worked with former colleague Bill Melendez on various Charlie Brown movies and television specials, eventually starting a studio called Playhouse Pictures, which produced commercicals for over 45 years.
