SMG4: Stupid Mario 3D World

Synopsis
Mario, Luigi, Peach, and Toad go on another whirlwind adventure. This time with 200% more stupidity and cats.

Plot
The episode starts out with Mario, Luigi, Toad, and Peach Toadstool, who was long absent up until now, watching the fireworks over the castle. While everyone praised the fireworks, Toad unsurprisingly wanted to use them to destroy the castle due to his hateful nature and his bad past with Peach, Mario, etc. Mario suddenly got hungry while watching and ordered Toad to get him some spaghetti. When Toad refused, Mario told Peach to make him a sandwich. Due to her bossy demeanor, Peach slapped him far onto somewhere near a clear glass pipe in response. The others came to check it out, and Peach told Mario to fix it. The unwilling Mario mocked her for being demanding, only to get kicked by her. Mario then hit the glass pipe with a toy hammer once, fixing it. The pipe then made many items (including a Furret) spew out of it. One of these things happened to be a Sprixie Princess, begging the gang to protect her from someone trying to capture her. Mario put her in a jar thinking she was a leprechaun. Suddenly, Bowser popped up and captured her, claiming that it was Bowser Jr.'s birthday and he wanted to get him a dancing leprechaun. With the Sprixie now captured, Peach forced everyone to go out and rescue her, much to Mario and Toad's shared chagrin (Since Bowser was doing it for his son), with Luigi following along.

The pipe took them to the Sprixie kingdom, but unlike the original, the place was overflowing with crime and corruption. While roaming through the city, Mario found a Super Bell, but was advised by Toad not to take it, since it transform the user into a cat. Mario later managed to find a pipe while racing a Yoshi, and it took them to a hill. To Mario's dismay, the gang had to get past a giant gap between them and a bridge. Mario threw Toad to the other side, Luigi just scuttle jumped his way through the gap, and Peach did the same through floating. Unfortunately, Mario ended up falling into the river, and the current kept pushing him away. The currents were so strong, it ripped Mario's arm (though it came back). Just when it seemed to be the end, Plessie saved him and took him to the other side.

The gang then found another glass pipe, which took them to a cloud level. Mario was so pissed that he punched a Biddybud in the face and shot Hisstocrat, who gave him a Double Cheery. When he ate it, it created an exact duplicate of him. Mario started to get happy with his clone (unintentionally insulting Luigi and forgetting about his existence), and the two went and annoyed Toad. Bowser then showed up in his car, with Peach noticing him. The gang fought him with Luigi punching Bowser, while the two Marios ground pound his face (to the latter's surprise that there were two Marios). Having enough, Bowser used a Super Bell to turn into Meowser (With Mario accusing him of being gay) and shot a fireball at Mario, only for Mario's clone to jump in front of it to sacrifice himself for Mario. Wanting to avenge his late clone, an angry Mario went after Meowser alone, using the Super Bell. However, instead of giving him a suit, it instead turned him into an actual cat, but nonetheless gave its powers.

Mario then found Meowser on a Skyscraper, and the Koopa King started climbing it, with Mario following suit. However, Meowser used his fire breath, forcing Mario to use a Pianta as a shield. Meowser then used a Double Cherry and created four clones of him, but Toad, using the Koopa Clown Car, shot then down, and cornered Meowser, allowing Mario to kick him in the penis. With the Sprixie rescued, Mario celebrated, but the Sprixie ruined his celebration by saying that Bowser kidnapped 6 other Sprixies. Not wanting to do everything all over again, Mario just sold her to a merchant (to the dismay of Peach and the others).

Goofs

 * When the characters entered the first glass pipe, Mario was the second character to enter, but when they exit the pipe, he was the last one to come out. The same thing occurs when the characters enter the glass pipe that leads to the cloud area, in where Mario is the last one to enter but the first one to exit.

Trivia

 * This is Peach's first speaking appearance since SMG4: The Mario Purge (Halloween 2018), as she herself notes and hence, counts as a fourth wall break.
 * One of the fireworks in the background is Reggie Fils-Aimé, who at the time of the video's release, was about to retire as president of Nintendo of America.
 * At 7:45, Kevin's picture of Mario from "SMG4 DRAWING BATTLE! (Mario, Bowser, Bob, Saiko and Shroomy)" is seen here.
 * The Blue Toad from the original game does not appear; instead, he is replaced with the usual Toad.
 * This is Bowser's first appearance in the flesh since SMG4: Mario's Hell Kitchen, as he only appeared in a hallucination in SMG4: Mario Gets Stuck On An Island.
 * This episode also marks Bowser’s reappearance as a villain, though he is still less villainous than he is in the actual game itself.
