hunters, Bender takes off his tuxedo. Unfortunately, since he had taught the penguins to hate anything that was not a penguin ("If it ain't black and white, peck, scratch and bite"), he and Leela come under attack. The penguins corner them on a floating slab of ice, but Fry arrives in the ship to save them. When it lands on the ice, it tips the block, sending the penguins sliding into the gaping mouth of a hungry orca. Leela and Bender board the ship, and everyone returns to Earth. Leela reasons that nature will set things right. Two penguins pick up guns left behind by the hunters and cock them at each other in a threatening manner. Continuity When Bender first reboots, he is initialized as "Penguin" because his display sees penguins. When Bender reboots later after being shot by Leela, he is initialized as "Human" because he sees Leela. This is another clue that Leela is a human mutant and not an alien (as is revealed in the season 4 episode, "Leela's Homeworld"). In season 7's "Forty Percent Leadbelly", as Dr. Beeler is browsing through Bender's file system, his Penguin Personality folder is shown next to his Main Personality folder. Cultural references The episode is a parody of the Exxon Valdez oil spill, with the dark matter tanker named the Juan Valdez; also referencing the Colombian coffee mascot. The fictional conservation agency depicted as Penguins Unlimited is a parody of the actual agency Ducks Unlimited, sharing the same criticism that the organization exists to merely fulfill the members' interest in hunting. The title of this episode is a reference to Robert Stroud, who was known as the Birdman of Alcatraz. Bender's speech to the penguins as they attack is a reference to Winston Churchill's famous "We shall fight on the beaches" speech. The scene where the killer whale tips the slab of ice to eat the penguins is a reference to the final scene of the 1977 film Orca. When Bender suffers an electric shock upon landing head-first on a slab of ice after being attacked by an orca, he whistles one of R2-D2’s signature beeps. During his state of sobriety, Bender can be heard singing "Greenland Whale Fisheries".
