Bob remembers that the town served as the filming location of a shark-themed ‘80s B movie, The Deepening.

The family discovers that the original prop shark from the movie is up for sale and convinces Fischoeder to buy it.

But Teddy encourages the townspeople to work together, and they begin brainstorming how to stop the shark, which is now heading towards Bob's restaurant.

Each of the townspeople's ideas goes horribly wrong and only serves to make the shark more dangerous: a spike strip becomes attached to the shark, an oil slick intended to “slow its momentum” ends up making it faster, and after it hits a telephone pole, it becomes electrified.

Bob is able to plug in the machine, and the shark, now filled with ice cream, finally ends its rampage.

On a news report, Hugo, the health inspector and "Quadrant Captain," takes credit for stopping the shark.

'"[2] Ross Bonaime of Paste gave the episode 8.3 out of 10, saying "The Deepening” is one of the more fulfilling episodes of Bob’s Burgers’ third season, making the family one singular unit against the shark (even though Tina’s allegiances are split), and having the family forced against the town is a familiar scenario, but it still works well.

“The Deepening” has one focused storyline instead of splitting the family into several that don’t feel fully fleshed out, and that makes for one of the funniest episodes so far this year.
