[1] Teddy tells the Belcher kids that the abandoned taffy factory, which is scheduled for demolition the following day, contains hidden treasure.
This turns out to be a joke, the punchline of which is that the map he draws looks like a butt, but Louise takes it seriously and convinces Gene and Tina to go with her that night to find the treasure.
Meanwhile, Bob and Linda have their scheduled sex night, though they have difficulty getting in the mood, and their plans are interrupted by the discovery that the children snuck out.
The episode ends with the revelation that the coastline around the factory perfectly matches the map drawn by Teddy, and that unbeknownst to the kids, Taff was full of gold bars.
"[3] Dyanamaria Leifsson of TV Equals gave the episode a positive review, saying "We don’t spend a whole lot of time in the restaurant, but “The Belchies” still delivers a simple story peppered with the kind of unexpected and outrageously funny lines that made me fall in love with Bob’s Burgers in the first place.
