"Leela's Homeworld" is the second episode in the fourth season of the American animated television series Futurama. It originally aired on the Fox network in the United States on February 17, 2002. "Leela's Homeworld" was written by Kristin Gore and directed by Mark Ervin. The episode reveals Leela's true origin as a mutant who was abandoned by her parents so she could have a better life. Her parents fabricated her prior background as an alien, as it is illegal for mutants to live on the surface. Plot The Professor announces some good news: Leela's old orphanarium has named her orphan of the year, and that he has invented a machine that makes glow-in-the-dark noses. The machine produces enormous amounts of toxic waste, and Hermes tells him to get rid of it. The Professor hires Bender for the job, and he dumps the waste into the sewer. At the orphanarium's award ceremony, the headmaster presents a story of Leela's arrival and Leela delivers a speech which profoundly inspires the orphans. However, back at Planet Express, Fry finds Leela in tears, and she admits she still longs to have parents, unaware that a pair of individuals each with a single eye like her are watching from underneath a sewer grate. Bender expands his one-time dumping into a full waste management service. The sewer mutants grow angry with Bender's disposal technique and abduct him, Fry, and Leela. The mutants sentence them to be lowered into a lake of chemicals which will turn them into mutants. Two hooded mutants break from the group and swing the crane the three are tied to, dropping them on the far side of the mutagenic lake. The mutant mob pursue them. Fry, Leela, and Bender take refuge in a mutant home, where they find photos and news clippings of every major event in Leela's life. Leela is frozen in horror at the thought of a mutant having been stalking her her whole life, giving the mob the opportunity to capture them. However, after a whispered word from the hooded mutants, the crew's sentence is commuted to exile. They are flown by hot air balloon to a surface access ladder hanging over the lake. Fry and Bender emerge on the surface, but Leela, determined to find out what the hooded mutants know about her, dives into the chemical lake. To her surprise, she is unaffected by the chemicals. Fry
