[1] Egghead Jr. is a large-headed and very intelligent baby chick and appeared in several shorts with bumptious Foghorn Leghorn (also a character directed by McKimson and voiced by Mel 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).
Egghead Jr. has the strange ability to accomplish virtually anything, simply by writing out physics theorems, then performing the action proposed thereby.
Egghead Jr. later hands Ed McMayhem a note telling him that he is studying for a very important exam and requests that he stop his laughing.
Egghead Jr., now renamed "Eggbert", makes frequent appearances in the Looney Tunes series published by DC.
