Editing On Her Majesty's Sewer Service

"'''On Her Majesty's Sewer Service'''" is the twenty-second episode of ''[[The Super Mario Bros. Super Show!]]'' It is a parody of ''{{wp|Goldfinger}}''. Its corresponding live-action segment is "[[9001: A Mario Odyssey]]."

This episode is notable for being the only episode where a [[Porcupo]] and a [[Spark]] appear. It is also notable for being the only episode of the show where [[Toad]] does not appear, making [[Mario]], [[Luigi]], and [[Princess Peach|Princess Toadstool]] the only characters to appear in every episode of the show.

The next day, [[Mario]], [[Luigi]] and [[Princess Peach|Princess Toadstool]] are sitting down to lunch at an Italian restaurant. Before Mario can thank Princess Toadstool for taking them out to eat, she pulls a hidden lever, sending their entire table down a shaft. As they descend, Princess Toadstool explains that they are going to [[Super Spy Headquarters]] because James Blond has been turned to stone, and the brothers are needed to save him.

At the bottom of the shaft, the trio ends up in an underground complex, where they are greeted by [[Secret Agent N]]. Agent N shows Mario and Luigi to their new [[Spymobile]], which Luigi comments looks like an old plumber's truck, though Agent N tells him that it packs more firepower than a battleship. Agent N then shows Mario and Luigi their new equipment, including a wrench phone, an exclusive drain cleaner, an atomic screwdriver, and, as Mario finds out, a laser drill.

Mario and Luigi reach Fort Hard Knox just as Koopfinger drives off, and they head after him in their Spymobile. Upon activating the plumber pulsion, they are able to speed up towards Koopfinger. The Koopa Troopa spots the Spymobile gaining on them, and Koopfinger remarks that it has to be the Mario Bros. Koopfinger pushes a button that opens a compartment in the back of the truck with a [[Snifit]] in it that shoots away at the Spymobile. It does not work, as Luigi points that the glass is Snifit-proof.

Vampa explains the simple rules of the game: She will spin the wheel to determine the Mario Brothers' fate. Vampa spins the wheel and it lands on "Tunnel of Doom". Vampa then pulls a lever, dumping Mario and Luigi in an [[Tunnel of Doom|underground tunnel]]. Luigi wonders why they call the place the Tunnel of Doom, when a [[Goomba]] starts chasing them towards a patch of [[Piranha Plant]]s. Mario and Luigi leap over the Piranha Plants, while the Goomba follows. On the other side, a [[Spark]] approaches them. Trapped between a rock and a hard place, Mario pulls out his Super Spy Hose Nozzle and Mini-Plunger, which he uses as a grappling hook to escape from the tunnel with Luigi.

Back in Koopfinger's hideout, Mario tells Luigi that they need to ambush Koopfinger. Meanwhile, Koopfinger's goons report about how they stole nine-hundred and ninety-nine billion trillion billion million and one coins from Fort Hard Knox. Koopfinger thinks that it is not enough, and announces that they need to pull another crime.

Mario and Luigi drop into Koopfinger's office from above, announcing that they are there to stop him. Koopfinger orders Mouser, Koopa Troopa and Tryclyde to attack Mario and Luigi. While Mario fights Mouser and Tryclyde with the atomic screwdriver, Luigi fights Koopa Troopa with a wrench, though it does not hurt him. Mouser throws his bowler at Mario, but it misses, knocking out Tryclyde ''and'' Koopa Troopa. Vampa White blows a fireball kiss at Mario, but he deflects it with his screwdriver and it hits Mouser. Vampa tries to get away from the fireball, but she gets caught on the Wheel of Misfortune, spinning it in the process.

Back at Secret Spy Headquarters, Agent N explains that James Blond is back to normal because Koopfinger is gone. Mario then smells pasta from the next room, and goes over to eat it. Agent N warns Mario that it is no ordinary pasta, but he is too late, as it blows up in Mario's face. Agent N explains that the pasta was his new spaghetti bomb, but Mario does not mind, because he mentions that he loves spicy food.

*When [[Bowser|Koopfinger]] throws the [[Bomb (object)|bomb]], [[Koopa Troopa]]'s head turns completely green. A similar error occurs when Mario and Luigi arrive at Koopfinger's hideout, where his head is completely yellow.
