Gene, Louise, and Tina discover a seaweed-covered object at the beach that turns out to be a large hunk of Ambergris - an extremely valuable, but illegal, by-product of whale poop that is used in high-end perfumes. But ...
Bob scores a temporary gig as a cook at an "underdog" frat house and discovers that he fits right in! Hijinks ensue as Bob and the rest of the fraternity brothers find themselves in the middle of a collegiate prank war that involves the house's most famous alumnus, Dr. Yap. Meanwhile, the kids are on a mission to invade the frat house and get in on the action.
Determined to have a perfect Thanksgiving, Bob meticulously prepares the family turkey. But, to his horror, he finds that someone then dumps the turkey in the toilet in an act of Thanksgiving sabotage.
In an attempt to redeem a failed talent show performance from her past, Linda reunites with her former band mates from, the Ta-Ta's, to perform at their high school reunion. At the event, a former female classmate attempts to impress Bob, her high school crush, who, in turn, becomes very self-conscious about the unwanted attention.
To Tina's delight, Bob becomes the substitute "Home Ec" teacher at her school and ends up creating a full-scale restaurant in the classroom. However, her excitement is short-lived as Bob's position causes father/daughter friction. But when Gene and Louise go to work for Bob's "school" restaurant, Linda must fend for herself at the family's "other" restaurant (aka Bob's Burgers).
After Linda accidentally kills the family tree, the Belchers must go out on Christmas day to find a new one. But when Bob cuts off a giant candy cane truck, they are forced to outrun the madman driver (homage to the 1971 movie "The Duel") and spend the entire holiday together in the car. Back at the Belcher home, Bob's friend, Teddy, accidentally gets stuck in the kids' Santa trap.
