Jynx, having landed a job with Sewer Maintenance Crew Number Thirteen largely due to "prior experience" in the sewers, is teamed up with a foppish Fox. The Fox decides to lead them into Tunnel Number Three, although, part-way in, Jynx notices that, according to a plaque, it is now Tunnel Number One. Jynx pauses to clean away at the grime on the plaque, revealing another numeral In reality, they've gone into Tunnel Number Thirteen, which is scheduled for flushing. And, of course, with the perfect timing of Jynx's bad luck, that time would be at the present.
Jynx and the Fox make a break for it, Jynx pausing to shed his suit so he can run better, while the Fox is overtaken by the waves. Jynx escapes into an access tube, but can't get the hatch shut, and is shot through the tube, coming out in a cavern chamber. What he mistakes for symbols of the ancients turns out to be grafitti. Pursued by ominous clacking noises from one of the other tunnels, Jynx escapes through a glowing tunnel … and into Faraon's Dome, where he surprises a Savanite gardener, and is pursued by two Vartan guards.
His means of escape apparently cut off, Jynx takes a desperate gambit, and leaps out of a chute, landing on top of a passing airship. Jynx's extended claws tear through the exceptionally flimsy envelope material, resulting in disaster. The ship turns out to be laden with crates of explosives that are quantum-uncertainty-sensitive … and will automatically detonate upon dropping below a certain altitude. Jynx hurriedly relieves the ship of this unwanted ballast, and the ship comes to a landing in the Vykarin Sea … whereupon a patrol ship, attracted by all the explosions, comes to rescue Jynx and the Savanites on board.
It turns out Jynx has accidentally thwarted a Babelite plot to blow up some target in Rephidim. He's a hero!
