Knothead and Splinter are the nephew and niece of Woody Woodpecker. They first appeared in the cartoon "Get Lost!." Originally Knothead and Splinter were Woody's nephews in the New Funnies comic books. Knothead was Nuthead and Splinter was a boy. But in 1949, Nuthead was turned into Knothead and Splinter was a girl. In the late 1950's Knothead and Splinter appeared in both animated cartoons and comic books. They were both voiced by June Foray. Woody was voiced by Grace Stafford/Lantz/Lanza. Knothead and Splinter had rivals such as Heckle and Jeckle, Chip N' Dale and the Goofy Gophers during their time. They also appeared in The New Woody Woodpecker Show.
