The Planet Expresscrew visits Duraflame National Forrest to go camping. At the visitor lodge, Ranger Park, the park ranger, says he is obsessed with Bigfoot and hopes to obtain proof of his existence. He shows a video which says that due to over-logging, Bigfoot habitats have become scarce. During the night, Bender Bending Rodríguez, annoyed with bugs, tricks Philip J. Fry I into leaving his tent so Bender can take it. In a clearing, Fry is abducted by aliens. When he returns, he finds that his nose is no longer on his face and that human noses are often used by aliens as an aphrodisiac known as "Human horn."
After searching the Galactic Bazaar, Fry, along with Turanga Leela and Bender, traces his nose to Lrrr who purchased it to help his failing marriage with Ndnd. He gets his nose back, only to have Bender ask Lrrr why noses and not the genitals, are used as the aphrodisiac. Lrrr is intrigued by this and orders Fry's "lower horn" to be removed. Leela, however, manages to make a deal that if the crew can help Lrrr's marriage by giving him and Ndnd a romantic dinner without using the "lower horn", Fry will be spared.
The plan fails as a result of a boring dinner and of Leela's singing, which the Omicronians consider an attack, thus Lrrr orders Fry's lower horn removed. Bigfoot interrupts them, closely pursued by Ranger Park, who plans on cutting off Bigfoot's feet to prove his existence. Lrrr saves the Sasquatch, but Park manages to cut a lock of hair. Lrrr almost proceeds to finishing removing Fry's lower horn but soon realizes that he'd be no better than Park. Ndnd, realizing that he is the sensitive Omicronian she fell for long ago, is in love with Lrrr again. They start making out and advise the others to get 500 hundred meters away as the trio go running for their lives. Bigfoot stays a bit longer to watch, then saunters off.
Sal has taken a turn for the worse. Until now his disorder resulted only in the letter "s" being appended to random words. In the advanced stages, as demonstrated here, the pluralization rules for irregular nouns appear, as when Sal says "bigfeet" rather than "bigfoots".
Hubert J. Farnsworth mispronounces "well" as "whell", but just afterward correctly pronounces "why".
