Louise leads Tina, Gene, the Pesto Twins, Jimmy Jr. and Zeke in a quest to find the secret treasure of an abandoned taffy factory.
Meanwhile, Linda and Bob try to have a romantic night until Bob starts feeling the side effects of a special pill Linda slipped into his casserole.
- Abandoned Warehouse: The abandoned taffy factory from "The Belchies", complete with Absurdly Spacious Sewer!
- Absurdly Spacious Sewer: Half the episode runs on this. Somewhat justified since the taffy factory sewers were used to smuggle alcohol during the Prohibition.
- Adult Fear:
- When Linda goes to check on the kids, she finds all of them gone, and then she reads Tina's diary and finds out they snuck to the taffy factory to find the treasure. When she and Bob show up, she even says she hopes they manage to find their kids before they get hurt.
- When the demolition team starts destroying the factory, all of the kids, Bob, and Linda are still underneath in the sewers, and those in charge of the demolition are none the wiser about it. Everybody was lucky to escape unscathed.
- Affectionate Nickname: "Taff", for the taffy dummy Louise befriends.
- The Alcoholic: Teddy mentions his uncle had a serious drinking problem.
- Art Evolution: This was the first episode of the show to make the switch from 2D rig puppet animation to traditional frame-by-frame animation, which is how it's been ever since. The animation for the rest of the series from this point on is noticeably more restrained and less "floaty" than the first season.
- Brick Joke: At the beginning of the episode, Teddy invites Bob to watch a game with a "Bring-Your-Own-Bean" Three-Bean salad party. Later, a construction worker mentions having a friend that hosted a "Bring-Your-Own-Bean" Three-Bean salad party.
- Cellphones Are Useless: Linda mentions that they need the fire department, but she can't call them because there's no service. Linda blames their awful phone plan, then Bob points they are underground so no cell tower waves can get through.
- Companion Cube: Louise grows attached to a taffy doll while she is stuck with it.
- Continuity Nod: In the pilot, one of the coffins in Mort's morgue contains Mr. Caffrey's corpse. In this episode, the kids end up exploring his factory, abandoned after his death.
- Damsel in Distress: Invoked by Tina; she believes that by acting helpless, she might conquer a man's heart, but it's just not for her to be helpless and she mentions to prefer taking action. Plus, Jimmy Jr. wasn't paying too much attention to her anyways due to bringing along his brothers and Zeke on the hunt.Tina: That's not who I am. I am a smart, strong, sensual woman.
Bob: Oh god...
- Diary: Tina wrote the kid's plan to find the taffy factory treasure in her diary, which is how Linda found out where they went.
- Gave Up Too Soon: Louise and the other kids fail to notice the butt shape mentioned in Teddy's story is actually based on the cliffs near the secret entrance under the taffy factory, and when she leaves Taffy behind on the beach they completely miss the fact that a gold bar was hidden in Taffy before he gets washed out to sea.
- Human Ladder: The group uses this to save Louise from the deep hole one of the booby traps knocked her into.
- Hypocrite: Tina invites Jimmy Jr. to the treasure hunt without asking Gene or Louise if it was okay, then gets angry when Jimmy Jr. invited his younger twin brothers and Zeke to it without asking her if it was okay. Louise wastes no time calling her out on it, though the sarcastic way she does so renders Tina oblivious to the irony.
- I Told You So: Louise accuses Taff of doing this, even though he is unable to speak.
- It's Quiet... Too Quiet: Bob and Linda discover that the kids snuck out because the three of them were never quiet when they sleep, prompting Linda to go check on them.
- Jerkass Has a Point: While she goes a bit too far with it, and eventually ditches her siblings to find the treasure for herself, Louise does have every right to be pissed off with them for how they've been more detrimental to the hunt than good (Tina invited Jimmy Jr., who in turn invited his brothers and Zeke, when Louise just wanted only the Belcher kids to find the treasure, while Gene messing around with the equipment ended up getting everybody stuck in an elevator).
- Living Crashpad: When Bob and Linda fall down the elevator shaft in the old factory, Bob ends up breaking Linda's fall.
- Raging Stiffie: Bob spends most of the episode with an awkward erection after Linda secretly slips him a penis pill.
Louise: I don't have to cut my arm off like that impatient idiot.
- The title is a reference to the movie The Goonies
- Louise refers to the story of Aron Ralston, who cut off his own arm when he got stuck in a dislodged boulder.
- Gene plays "Aqua Boogie" by P-Funk twice in the episode.
- Sleeping Dummy: The kids use these when they sneak out of the house. Louise uses an inflated ballon and bundled-up clothes, Gene uses a stuffed garbage bag, and Tina simply leaves a post-it note with her name on it.
- Strange Minds Think Alike: Louise realizes that the treasure map might be real because if she were to ever make a map, she would choose to make one shaped like a butt.
- Tastes Like Feet: Gene, Andy and Ollie start licking the machinery in the taffy factory.Gene: I can taste all the flavors from the past sixty years. I can taste the Korean War!
Andy: I taste rust.
Ollie: I taste Andy's spit.
- Too Dumb to Live: Louise accuses everybody of being this. While Tina and Gene show a glimpse of capacity of surviving on their own, the other four do get caught in a trap when left alone.
- Treasure Hunt Episode: In an old taffy factory.
- Unrequited Love Switcheroo: Tina spends the episode trying to woo Jimmy, only to lose interest when he shows signs of liking her. Ultimately, she goes back to liking him after seeing his ass.
- Wham Shot:
- The shot showing that the cliff where the Taffy Factory is the butt-shaped structure that Teddy's uncle talked about.
- Taffy having gold inside of him.
- Whole Plot Reference: To The Goonies, complete with a treasure hunt and Louise befriending what she believes is a humanoid monster. Cyndi Lauper even performs a parody of her theme song, "The Goonies 'r' Good Enough," during the credits.
