Misadventure of Mighty Plumber

Misadventure of Mighty Plumber is the twelfth episode of The Adventures of Super Mario Bros. 3. It usually aired right after Oh, Brother!

Plot Synopsis
The episode begins with Mario and Luigi watching what would appear to be a horror (judging by the heard scream) when Luigi cowers in fear of what's going to happen to the woman on TV, and Mario complains about him overreacting about the show, which they had gotten a TV from Brooklyn to watch. The TV is seen with a woman in front of a sink, from which strange green slime is being produced. Luigi shouts at the woman to call Mighty Plumber, which she immediately does. Just as it appears the slime (which has formed into a monster) is going to get the woman, the show cuts to a commercial. Mario and Luigi think about how Mighty Plumber will be able to save her.

Meanwhile in Castle Koopa, Bowser appears to be doing some sort of excercise by jumping up and down, when Big Mouth and Bully appear and join him. King Koopa shouts that he's having a tantrum, not doing excercises; this is because of the fact that he found a map into the Pipe Land's Coin Treasury, but he knows that Mario and Luigi will manage to stop him. At that moment, Hip and Hop run in and inform him of what Cheatsy is doing; using his Magic Scepter to make the toys in commercials magically come out of the television. He zaps out a race car for Hip and Hop, to Koopa's annoyance. But then, he sees the TV Cheatsy had rigged when The Adventures of Mighty Plumber comes back on, and he saves the woman that was seen earlier. Bowser gets the idea to blast Mighty Plumber out of the television and help him rid the Marios. He takes Cheatsy's scepter and zaps Mighty Plumber out of the TV. He tells them that two "evil plumbers" are trying to steal the gold Coins from the Pipe Land Treasury, and that his help will be necessary in bringing the Coins to his castle to keep safe, to which a naive Mighty Plumber agrees.

Back at Toad's house, the Marios' TV is on the fritz, and the distracted brothers don't notice a Venus Fire Trap until it spits flames at the wall. The ashes read Robbing Pipe Land Treasury - Dare you to stop me... Your Enemy, King Koopa! Mario says that they must stop Koopa, as Mighty Plumber would.

Bowser and Mighty Plumber are now in Pipe Land, in front of the Underground Maze of Pipes, the location of the hidden treasury. Mighty Plumber cracks open an entrance, only for water to spew out all over Koopa. He decides to wait elsewhere, and thinks about what to buy with his Coins, but is soon interrupted when Mario and Luigi arrive. Bowser tells Mighty Plumber that the nasty plumbers are here, only for the brothers to ask for an autograph. However, Mighty Plumber attacks them with a plunger, and they leap away several times. Eventually, they jump into a water-filled Warp Pipe, and Mighty Plumber sends down a "plumber snake". Luigi stuffs it into a smaller Warp Pipe growing out of the side and they swim further into the pipe. The snake re-emerges out of the other end of the Pipe, which is right behind Bowser. It grabs ahold of him and he pops out the other end, at which point he tells him to stop "fooling around", as their time to get the Coins in the treasury is minimal.

Below in the maze, Mario and Luigi remember Bowser's message about robbing the bank and try to get there as soon as possible; only to find two paths ahead of them. Playing "eeney-meeney-miney-Mario", Mario decides to take the left one and Luigi follows. On the other end, they look around and hear King Koopa's voice, talking about the vault being nearby. Luigi worries that Mighty Plumber's show will be cancelled if he steals the Coins, but Mario hatches an idea to steal Koopa's map. Luigi then taunts a Venus Fire Trap until it pops out of a Warp Pipe. It attacks Luigi and Mario struggles with it, but it bites Luigi on his rear end. Mario uses it as a rope and lowers Luigi down another Warp Pipe - however, Luigi's pants rip and he falls right before Bowser. He grabs the map and runs off, when Koopa tells Mighty Plumber to attack him.

Mighty Plumber tosses his plunger at Luigi, and Koopa snatches the map back. Mario jumps down the Warp Pipe and stomps Mighty Plumber's foot, grabbing hold of the plunger. He throws it in Bowser's eye and grabs the map. A chase scene then begins to the song Chill Out. When the chase ends, Mario finds that Bowser and Mighty Plumber somehow got ahead of them when their footprints are marked beyond their path.

Sure enough, Bowser and Mighty Plumber reach the Treasury, and Mighty Plumber breaks the door open. Koopa runs in and uses Cheatsy's scepter to force all the coins into his burlap sack. A sort of security system of a flood goes off, when Bowser abandons Mighty Plumber. Mario and Luigi appear in a gap in a high end of the wall. Mighty Plumber calls himself a disgrace to the profession of plumbing, but Mario and Luigi tell him that he's their hero, and that they learned great tricks from him like the battering ram, which they immediately use - they stuff a clogged pipe into one of the pipes spewing water until it blasts out and breaks the door down.

Just as Bowser is about to exit the maze with the coins, Mighty Plumber throws his plunger, now attached to a rope, at Koopa. He yanks on the rope, but Koopa stomps the plunger and breaks it. He jumps out with the money, although Mario and Luigi quickly turn the crank of a Warp Pipe that sprays water into the one Bowser used to exit. Just as Bowser begins celebrating, the water floods his castle and sends him plummeting into a hole in his floor. Cheatsy sees the left-behind money and tries to grab it, but runs away when the three plumbers show up. Mighty Plumber uses the snake to grab Cheatsy by the tail, and Mario tells him to send Mighty Plumber back into the television. Cheatsy does so, and Mario grabs his scepter so that no more television-related mischief will happen. The bros. then return the money to the treasury where it belongs.

Later at Toad's house, the Mario Bros. are watching Mighty Plumber when the title character gives them a thumbs up. Mario proudly tells himself and Luigi that they're real heroes.

Trivia/Goofs

 * About forty-five seconds into the episode, when the show cuts to the outside of Castle Koopa, the flag of Japan can be seen.
 * The Mario and Luigi dartboards from Oh, Brother! (the previous episode) can be seen a few times.
 * When Bowser tells Big Mouth and Bully about his plans to rob the treasury, their heads are orange.
 * When the woman in Mighty Plumber is seen screaming when Bowser first sees the TV, the background is Castle Koopa.
 * If the Warp Pipe King Koopa took towards the episode's end led straight to his castle, he and Mighty Plumber could've gone through it in the first place rather than having to go through the entire Underground Maze of Pipes.
