Stupor Duck (1956)

Continuity mistake: When Cluck Trent is telling us about Aardvark Ratnik, he is holding a paper cup in his left hand. When he says "This looks like a job for Stupor Duck!" we cut back to Trent, and the paper cup has disappeared.

Trivia: In the opening sequence, the announcer says that Stupor Duck is "more powerful than a steaming locomotive" and we see a barely functional train. What you actually see is a clip from the 1945 Warner Brothers cartoon, "Hare Trigger."
