Nine years after their debut in The Fox and the Grapes, The Fox and Crow made their last theatrical cartoon for Columbia (and third for UPA) with this, Punchy de Leon. As you've probably guessed by the title, this short concerns the efforts of the leading characters to find the Fountain of Youth for the king of Spain. Some amusing animation gags abound in the two competitors' efforts of oneupmanship of each other though the topper comes at the end which, if you've seen many of similar cartoons, you'll figure out right away. While this was indeed the final animated appearance of these now-obscure characters, The Fox and Crow would continue in comic book form for DC for at least 18 more years. By the way, though no credit of him is on this IMDb listing, that certainly sounds like Daws Butler's southern voice that he later used for Huckleberry Hound briefly coming out of the Crow's mouth when he poses as a toll guard!
