Misadventure of Mighty Plumber Episode Guide

The Adventures of Super Mario Bros. 3 Episode 12 – Misadventure of Mighty Plumber

Mario and Luigi are at Toad's house, watching their favorite television show, The Adventures of Mighty Plumber, when Luigi cowers in fear of what is going to happen to the woman on TV. Mario complains about Luigi overreacting about the show, which they are watching on a TV they had brought from Brooklyn to the Mushroom Kingdom to watch. The TV is seen with a woman in front of a sink, from which some strange green slime is being produced. Luigi shouts at the woman to call Mighty Plumber, which she immediately does. Just as it looks like 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, at Kastle Koopa, King Koopa appears to be doing some sort of exercise by jumping up and down, when Big Mouth and Bully appear and join him. Koopa shouts that he is having a tantrum, not doing exercises; this is because of the fact that he found a map leading into the Pipe Land Treasury, but he knows that Mario and Luigi will manage to stop him if he attempts to go there. At that moment, Hip and Hop run in and inform him of what Cheatsy is doing: using his magic wand to make the toys in commercials magically come out of the television.

Cheatsy zaps out a race car for Hip and Hop, to Koopa's annoyance. However, Koopa sees that The Adventures of Mighty Plumber comes back from commercials, and Mighty Plumber saves the woman that was seen earlier. Koopa gets the idea to blast Mighty Plumber out of the television and trick him into helping him get rid of the Marios. He takes Cheatsy's scepter and zaps Mighty Plumber out of the TV, then tells him 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 naïve Mighty Plumber agrees.

Back at Toad's House, the Marios' TV is not working, and the distracted brothers do not notice a Fire Piranha Plant outside, until it spits flames through the window and 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.

King Koopa and Mighty Plumber are in Pipe Land, in front of the Underground Maze of Pipes, the entrance to 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. Koopa 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 his plumber's 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 Koopa. It grabs a hold of him and he pops out the other end, at which point he tells Mighty Plumber to stop "fooling around", as their time to get the Coins in the treasury is minimal.

Trivia & Bloopers

When the woman goes over to the phone to call Mighty Plumber, it is gray, but in the next shot, it is yellow. In the shot afterwards, it is blue. In the same scene, the slime monster's eyes and the top of the woman's dress are white instead of yellow and green, respectively.
Initially, the slime monster is green, but when the lady says, "My hero!" it is brown.
When the commercial break is about to start, the slime monster's animation repeats.
When Mario says for Luigi to count on Mighty Plumber, it is rainy instead of sunny.
This is one of the few episodes in The Adventures of Super Mario Bros. 3 where Princess Toadstool and Toad do not appear. This is also one of the only episodes where the Koopalings have minor roles. Bully, Big Mouth, Hip, and Hop only appear in the beginning, and Cheatsy does not accompany King Koopa in the Pipe Maze, with King Koopa being accompanied by Mighty Plumber instead.
The Mario and Luigi dartboards from the previous episode "Oh, Brother!" can be seen a few times.
