Looney Tunes

It marks the first appearance of Elmer Fudd (voiced by Arthur Q. Bryan), who had evolved from Tex Avery's "Egghead," and the last appearance of Happy Rabbit (excluding Elmer's Pet Rabbit, where he was billed as Bugs Bunny, the first instance of that name being used on-screen, and a cameo in a later cartoon Patient Porky) until Looney Tunes: Back in Action (first re-seen in deleted scene).
