Tina, Gene and Louise are filled with the Halloween spirit and head out with their friends for a candy-fueled adventure. However, things take a turn for the worse, when the kids build their own fort and find themselves held hostage by Louise's wacko friend, Millie.
Linda is bored by Bob's tired attempts at Date Night and decides to sign up for flying lessons. When Bob won't join her, she becomes the target of "Upskirt Kurt" the most charming pilot in the air.
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. Then, to his horror, he finds that someone then dumps the turkey in the toilet in an act of Thanksgiving sabotage.
Haunted by a poor talent-show performance from her high-school days, Linda gets back together with her former bandmates to rock their class reunion. Meanwhile, at the same soiree, Bob becomes bothered by the attention being paid him by a former classmate who had a crush on him.
Tina is delighted when Bob fills in as substitute home-economics teacher at school and creates a fully operational restaurant in the classroom. Unfortunately, some father-daughter friction develops. Meanwhile, the other Belcher kids take jobs at the school restaurant, leaving Linda to run the burger joint by herself.
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 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.
In an effort to help socialize Louise, Linda invites four of her classmates over for a surprise slumber party. Meanwhile, Bob cooks a burger to catch a renegade raccoon.

To compete with fellow “restaurateur,” Jimmy Pesto, and his blowout Super Bowl event, Bob is determined to create a Bob’s Burgers commercial to air during the “big game.” In an effort to outshine Pesto, the Belchers recruit Randy, a documentarian, to assist with the filmmaking and hire on former pro football star Connie Frye to be the celebrity endorser.
Bob and Linda visit school and learn that their kids' essays about their fantasy version of Wagstaff are “too creative” and “offensive.” Eugene transforms the school into a “Fart School for the Gifted” (watch out for Keyboard Jail); Tina, to her delight, depicts a world where she is romanced by countless zombie teenage boys; and Louise creates a school where she takes down a robotic Mr. Frond from the future (“We need more creamed corn!”).
Tina isn't invited to her classmate Tammy's Bat Mitzvah, but ends up at the party anyway, because Bob and the family were hired to cater. A total "Bat-zilla," Tammy's theme is, well, "Tammy," and despite the invite snub, Tina is excited to scope out the BFOS (boys from other schools). Things go awry and Louise and Tammy end up missing, so, to her total delight, Tina is left center stage.
When Bob and Linda leave town for a romantic getaway (at a Burger Convention), they ask Teddy to babysit Tina, Gene and Louise. While the 'rents are away, Teddy is eager to earn the coveted title of "Uncle Teddy" and does so by putting Tina's crush in his rightful place after discovering that he was just using her for – gasp – free burgers! Hijinks ensue.
The Belchers take a trip on a train and, to their dismay, Louise, Gene and Tina are seated in a separate train car. Never one to follow the rules, Louise ropes the children into helping her on her mission to steal the vast chocolate supply from the restaurant car! Meanwhile, Bob and Linda indulge in some wine tasting and have a “taste-off” with a snobby couple.
After predicting that a telemarketer is calling the restaurant when the phone rings, Linda and the kids believe that she is a psychic. Needless to say her “predictions” irk Bob and spell out hilarious happenings.
In an homage to the “Bronies” subculture, Tina attends her first Equestra-con, a convention based on her favorite animated pony show, “The Equestranauts.” To her surprise, she finds that the show’s fans are middle-aged men (called “Equesticles”). When a powerful super-fan tricks Tina out of her rare toy pony, it’s up to Bob to go undercover to get it back.
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 Louise tries to cheat Gene and Tina out of the profit she hopes to make by selling the treasure on the black market. Meanwhile, Bob and Linda deal with their psychologically unstable landlord who is building them a new bathroom.
Upon learning that she has a cavity and needs a filling, Louise runs away from the dentist's office and seeks refuge at Aunt Gail's. When Louise refuses to go home, Linda sends Tina and Gene to join her and bets her that she won't last the weekend with Aunt Gail's "craziness".
Tina decides to try out for the cheerleading squad, but it’s actually Gene who gets noticed in the crowd for his spirit and cheering ability. Meanwhile, during her cheer audition, Tina falls and bites her tongue, leaving her unable to speak – and a mischievous Louise steps up to be her translator.
Motivated by the promise of a new beachside burger joint, Bob conspires with Felix to convince Mr. Fischoeder to sell Wonder Wharf. Meanwhile, Tina protests the destruction of the wharf's carousel by chaining herself to it.
It’s Linda and the kids to the rescue when Felix takes desperate measures, and puts Bob and Mr. Fischoeder in danger.
