The Last Angry Moose is the sixth story arc from the second season of Rocky and His Friends. It was broadcast on ABC during the 1960-1961 television season. It depicts Bullwinkle using his mattress money to seek Hollywood fame under the name "Crag Antler", supervised by Boris posing as director D.W. Grifter.
After seeing a movie with an actor acting as a tough-guy, Bullwinkle claims that he can act just as convincingly. Attempting to do so, several women nearby faint (due to a couple of unseen mice). Thinking he really does have acting talent, Bullwinkle takes his money-stuffed mattress, and heads for Hollywood. Bullwinkle soon is discovered by director D.W. Grifter (aka Boris Badenov in disguise). Boris also takes on the persona of an acting coach, helping to empty Bullwinkle's mattress, until finally Bullwinkle makes his debut as Crag Antler in the film "The Last Angry Moose". "The Last Angry Moose" becomes a comedy sensation; however, upon hearing the audience laughing instead of taking him seriously, Bullwinkle and Rocky return to Frostbite Falls, and Bullwinkle considers his acting career to be finished.
