Egghead, Jr. debuted in 1954's Little Boy Boo, and made two subsequent Looney Tunes appearances in 1955's Feather Dusted and 1960's Crockett-Doodle-Doo.
Egghead, Jr. is a large-headed and very intelligent baby chick and appeared in several shorts with bumptuous Foghorn Leghorn (also a character directed by McKimson and voiced by Blanc). The only child of Miss Prissy, a widow hen, Egghead, Jr. was bookish and never talked (though he mumbled when he counted playing hide-and-seek with Foghorn in Little Boy Boo). Foghorn would try to teach him to play games like baseball and cowboys and Indians, with the intent that he act more like a typical boy, but invariably resulting in bodily injury for Foghorn.
In 1991, Egghead Jr. appeared in the Tiny Toon Adventures episode "Hog-Wild Hamton"; he's Hamton's neighbor and he doesn't like being disturbed, so when a wild party takes place at Hamton's house and the guests refuse to keep the noise down, Egghead takes matters into his own hands. Egghead Jr. also makes a cameo in Star Warners.
