Mario tries to collect all the shine sprites and clean up the town after being framed. Except he just makes everything worse.
Now the Delfino Airstrip in clear view, a Polluted Piranha Plant appears to be polluting the area. The Toad piloting the plane, frightened, quickly lands and stops just in time, Mario is then ejected from the plane due to not wearing his safety belt. Peach, Toadsworth and the pilot come out to investigate. Toad then says "What's this icky paint like goop?" before getting eaten by the Piranha Plant. Toadsworth decides to ignore it and announces vacation.
Later, Toadsworth holds Mario with a leash, and Peach suggests that they go to an amusement park, Toadsworth asks Mario for his opinion, but to his dismay, he had already disconnected from the leash, causing Toadsworth to react with great displeasure.
Mario is then seen walking in Delfino Plaza with funky-looking shades on. To the Pianta's surprise, they think he looks like a weirdo.
The "Po Po" believe Mario to be the perpetrator that has put graffiti on the island and proceed to attempt arresting Mario, who thinks it's because that he was naked on the plane during the trip to Isle Delfino.
Mario is then chased around the Plaza until he spots Professor E. Gadd cleaning his Lamborghini with F.L.U.D.D (Flash Liquidizer Ultra Dousing Device) Mario then proceeds to kick E. Gadd to steal F.L.U.D.D from him as a getaway device. Mario then proceeds to hold F.L.U.D.D in way resembling obtaining an item from Zelda.
The Police begin to yell at Mario, telling him to drop F.L.U.D.D or he will be fired upon on, which Mario promptly tells them "F*K U". Police recognized this, thinking that Mario figured out that they didn’t have any fingers to shoot.
Mario then uses the Hover Nozzle to escape, announcing that he is invulnerable, not before falling back to ground level and beginning to yell in pain. The police decide to then call the military, (Driving a tank directly towards Mario, then exploding on contact.)
Mario, now in the defendants position; there’s a missing defense attorney. A Pianta Prosecutor speaks that by now, everyone should know about the one who has been defacing the plaza. Footage is then shown depicting a Mario-like person (ala Simpsons Mario) plastering graffiti everywhere, including the inhabitants, as the he speaks, Endangering our way of life. Mario glances at the footage and asks about the handsome delinquent on screen.
The prosecutor then shows a sketch of Mario (An indeed sketch of Mario, derpishly wrapping his arms around a Power Star) Saying that drawn based on eyewitness’ description.
The Jury, (3 Piantas) then freak out, one of them retorting “My Eyes!” The audience also gasps in disbelief. Mario tells them to stop criticizing the footage.
The prosecutor then begins to deliver his opinion, stating that the truth is obvious. Before finishing the sentence, Mario then objects (MAMAF!KER). He asks if he can phone a friend, thinking he was in a game show during the entire court session. The Judge allows him, (likely thinking that Mario’s calling a witness) Mario proceeds to scream in the phone, telling Toadsworth that the courtroom is full of intellectually disabled “tree people” Nobody answers the phone; Peach and Toadsworth are already enjoying vacation.
The Judge finds Mario guilty, sentenced that he will clean up all the graffiti and locate the missing Shine Sprites in Isle Delfino. Mario refuses, the attempts to make a run for it; he is then halted by the courtroom doors. Mario tries to make peace and asks if they can open the doors for him. The guard doesn’t agree with Mario’s demands.
Mario is dumped back at the airstrip and is instructed by Piantan Authorities to clear the runway of the Polluted Piranha Plant. Mario give the plant a good look, before turning back to the 2 Police Piantas, responding by giving Mario a shrug to try his best.
Mario takes off F.L.U.D.D, and tells him he doesn’t need assistance; he proceeds to jump towards the Piranha Plant, midway falling, he regrets it and is consumed. He is soon spat out due to not tasting good.
As the judge demanded, Mario decides to collect Shine Sprites. However, his attempts to help others result in Isle Delfino being thrown into even more chaos than before.
Eventually, Mario discovers the imposter and chases him, who as in the original Super Mario Sunshine turns out to be Bowser Jr. He puts him in a crib as punishment for framing him, only to be chased by the police force for his chaotic actions while collecting Shine Sprites.
In a bonus scene at the end of the credits, Il Piantissimo discovers the magic paintbrush on the beach. He then calls it a new @$$ scratcher.

- This is the final video to play the Retarded64 intro, however the video is labeled as "SMG4" rather than "R64". Whether this blooper was intended to be part of the series or not remains unclear.
- This is due that in FISHY BOOPKINS helps with Mail - SMG4 Mail Time#12, Luke announced that Retarded64 will be removed from the title of future videos because YouTube now demonetizes videos with inappropriate use of family entertainment characters.
- The theme that plays after Bowser Jr.'s defeat is Jason Farnham 's "Get Outside", which is coincidently Bowser Jr.'s theme in SuperMarioLogan.
- When Il Piantissimo finds Bowser's Paint Brush after the outro, it's a reference to Super Mario Sunshine where if the place doesn't collect 120 Shine Sprites before beating the game, Il Piantissimo finds Bowser's Paint Brush in the ending.
- Mysteriously, when Mario equips the F.L.U.D.D, he changes into a custom SM64 model with the F.L.U.D.D.
