Here is an early Tiny Toon Adventures episode featuring a memorable team-up between Daffy Duck and his protege, Plucky. It is, to my knowledge, the only time Marvin the Martian ever appeared on the show (with a daughter, yet!)
The animation is horrible, as the overseas animators hadn't quite gotten the hang of the show's style yet. But it's notable for a couple of reasons: One, Maurice Noble himself designed the backgrounds and worked on the story, and Two, it's one of Jeff Bergman's last Warner cartoon voice roles. Joe Alaskey, who voices Plucky and Marvin here, later assumed the role of Daffy, and remains Daffy's voice to this very day.
