Each episode featured three segments in the form of three unrelated cartoons: George of the Jungle, Tom Slick, and Super Chicken.[3] All three theme songs were written by the team of Stan Worth and Sheldon Allman, with Worth primarily composing the music and Allman handling the lyrics.[4] Each of the cartoons ended with a strike on the tympani (kettle drum), which changed to an ascending tone, following a pun.
Unlike previous Ward series, the animation production was done in Hollywood using veteran animators Phil Duncan, Rod Scribner, and Rudy Zamora, among others. Ward mainstays Bill Scott, June Foray, Paul Frees, and Daws Butler provided most of the character voices over all three segments.
The cartoons are technically more advanced than the animation in Ward's earlier series, which originated from Gamma Productions, a Mexican studio sponsored by Ward. He was so pleased with George of the Jungle that he allowed production to go over budget, which resulted in considerable financial loss, ultimately limiting the series to 17 episodes.
In 2008, Classic Media and Genius Entertainment released the complete series on DVD.[5]
