The Birdbot of Ice-Catraz

Professor Farnsworth gives the crew the controversial mission of towing a dark matter tanker on a dangerous path through the Solar System, which includes a very low fly-by near a penguin colony on Pluto. Leela refuses to take part and leaves to join an environmentalist group named Penguins Unlimited, so the Professor makes Bender the new captain of the Planet Express ship. After initially failing to stop the tanker, Leela and the protesters race ahead to intercept the tanker at Pluto. Meanwhile, aboard the Planet Express ship, Bender lets his new power go to his head. Fry gets fed up with Bender's captaining, and rejects both his leadership and friendship. A distraught Bender, unwilling to drink on his own, goes on a sobriety binge^{[note 1]} and ends up flying the tanker on an erratic course over Pluto, where it collides with an iceberg and spills dark matter across the penguin colony.

For his part in the disaster, Bender is sentenced to community service cleaning up the spill alongside Penguins Unlimited. However, when the police officers supervising him are distracted, Bender dons a tuxedo and blends into the colony of penguins. Leela sets off to search Pluto for Bender, while Fry inexplicably decides to take the Planet Express ship and search for Bender in space. That night, Bender is forced into a hard reboot after an orca attack, and his boot loader reinitializes him with penguin-like behaviors. The next morning, Penguins Unlimited discovers that the dark matter spill has caused the penguins' fertility rates and incubation periods to accelerate exponentially, and that the colony is already suffering from overpopulation as a result. The group declares open hunting season on the penguins as a drastic measure to spare them from mass starvation, and Leela reluctantly agrees to take part, but her first and only victim turns out to be Bender, who reboots into his normal personality after she shoots him.

When the hunters arrive, Bender leads a large force of penguins in an assault. After the penguins succeed in driving off the 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.

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. In the beginning of the episode while the professor is going over the mission, he points out the path using the "fing-longer". season 2 "Anthology of Interest I"

• 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 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.
