Mr. Fischoeder gets the mechanical shark used in an old B-movie filmed in town as a new attraction for Wonder Wharf. Thanks to the kids' curiosity getting the better of them, the shark breaks loose and causes a ruckus.
- Ambiguously Bi: Tina seems rather interested in the Fanservice of the "The Deepening 3".
- Attack Backfire: The town's attempts to stop the shark (with a spike strip, an oil slick, and a giant crane) only make it stronger.Bob: Okay, we gave the shark spikes... Okay, we made the shark faster... OKAY, NOW THE SHARK IS ELECTRIFIED!
- Bait-and-Switch Comparison: "Who was Tina really gonna choose, a broken-down wreck with the dead eyes, or a fake shark?"
- Best Known for the Fanservice: In-universe and inverted. Bob does not remember that "The Deepening 3" heavily relied in a lot of fanservice-y scenes and topless car washes, only remembering the shark.Bob: This movie is like 90% topless carwash.
- Call-Back: The soft serving machine becomes a plot point again, for the first time since "Synchronized Swimming".
- Dark Secret: Teddy has one from his time working on "The Deepening 3", but it turns out to be nothing major, just that he blames the shark for losing a girl.
- Dirty Coward: Hugo makes fun of Bob, Teddy and Mort when they go after the shark, but when they ask him to go with them to fight it, he says he is busy with "crowd control" even though there is hardly even a crowd.
- Evil Is Petty: Hugo, who insists in annoying Bob with his Quadrant Captain duty.
- Hidden Depths:
- Teddy used to be an actor.
- This episode hints again that Bob is a movie buff, based on his knowledge of "The Deepening" series.
- I Was Quite the Looker: Teddy as it turns out was quite hot in his youth, playing a hot life guard in "The Deepening 3".
- Literal Metaphor: As he reaches for the straw dispenser to throw it at the rampaging shark, Bob yells "I am literally grasping at straws!"
- Misplaced Retribution: Bob points out that technically Teddy should be angry at the shark operator for ruining a possible relationship, not the shark itself since it's just a prop. Teddy realizes Bob has a point but still goes back to wanting to destroy the shark.
- Not Evil, Just Misunderstood: Tina believes the shark is just confused and wants to go home.Bob: Tina, it's a mechanical shark. It's dumber than our toaster.
Tina: Our toaster is also confused. It doesn't know why we put bagels in it.
- Oblivious Janitor Cut: There is a janitor listening to a headphones who is completely unfazed by the fact that a giant shark just shattered the window he was vacuuming next to.
- Police are Useless: Instead of dealing with the shark, the police and the firemen fight over who gets to deal with it, and the citizens are the one that have to deal with the shark.
- Threatening Shark: The mechanical shark actually becomes a threat when it goes haywire, falls on its side and "swims" its way out of Wonder Wharf and down the block.
- Whole Plot Reference: To Jaws, down to the final scene on the restaurant being basically a reenactment of the scene where the shark attacks the boat.
