After a portal teleports the SM64 Bloopers cast from Peach's Castle to the real world, SMG4's house fills with all sorts of chaos. Getting everyone back home proves a difficult enough task on its own; in the meantime, SMG4 has to deal with the characters' antics.
At a dark time in the Mushroom Kingdom (it is unclear whether it is morning or night), Mario is walking to SMG4's room for help with the oven, only to find the computer with Project64 running. Mario wonders if there are still naked spaghetti pictures on the computer, and attempts to close Project64, but instead of closing the emulator, the screen changes to a webcam of the real life SMG4, confusing Mario. An error then clogs up the screen as it creates a dark-coloured portal. Mario is sucked into this portal and is transported to another world.
Meanwhile in the real world, the real life SMG4 is playing Project64 and can't find Mario in the room he was just in. He hears Mario‘s voice, who quickly comes out of the computer and hits the wall. SMG4 looks at Mario in confusion, right as he wakes up. SMG4 asks Mario what he's doing here, Mario asking how he knows his name. SMG4 tells him that he's SMG4, Mario not believing him as SMG4 is not Asian, and wears a cap and has a mustache like him, SMG4 teold him that everybody looks like that, Mario still not believing him, and runs out, hoping to find a way home.
SMG4 searches throughout the house and finds Mario in the kitchen, throwing stuff out from the fridge. SMG4 asks him to not throw the food, Mario wondering where his spaghetti is and grumbles in anger.
Meanwhile, Luigi is searching for Mario and finds the portal in the same room. Peach comes in and Luigi tells her to stay back, Peach states that it won't suck her in. Almost immediately after, she gets pulled in, with Luigi following suit. Toad then breaks down the door with confidence and follows the two in.
SMG4, who is with Mario, hears the noise of the others crashing in his room. When he goes to check, Luigi (who is sad because his mustache is crooked), Peach and Toad are all confused, Toad is especially confused by a 1-up plush whom he mistakes for his dad. SMG4 gets even more confused right as Mario reveals he's naked, SMG4 telling him to put on some clothes. More characters fall victim to the portal, including Bowser, Wario, Waluigi, Shy Guy and Po. SMG4 is still trying to figure out what's going on, and asks them all what they are doing in his house. Mario asks where the SMG4 he believes is real is because he thinks the real life version of him locked him away and decided to do the same for all of the other characters, while Waluigi sees a doll of himself in Petey Piranha's mouth and thinks he "doesn't look too sexy in this world" (possibly thinking he'll get eaten). The Shy Guy doesn't seem bothered as Mario orders them all to attack SMG4. They do so and SMG4 manages to defend himself, until Toad ambushes his face and he passes out.
He wakes up to find that they are scattered all over his house causing mayhem. He first finds Wario sleeping next to him (possibly keeping guard until he fell asleep) and then Luigi on his computer, watching a video of some naked people doing the Harlem Shake; he notices SMG4 and gets worried. He tries to explain it was in the suggestions before starting to cry. SMG4 just silently goes out of the room. He notices Toad in the toilet and asks him to get out, Toad refusing because his "people are calling him." SMG4 pulls out a sword and warns Toad to not make him come in there, Toad instantly bolting out in fear.
He finds more chaos as the Old Man Hobo is revealed to have come through and is in the bath asking for shampoo. Waluigi runs past behind SMG4, who follows him to find his living room is overrun by Toad, Waluigi, Mario and a flaming Peach. He goes to the kitchen to find Po cooking Tubby Custard, and the Shy Guy toasting toast. Bowser runs behind him, and goes outside and wears a skirt and a bra. It is revealed that Lakitu came through as well, SMG4 not pleased, but gets even more nervous when he notices a car coming to park, and that the driver is his brother Kevin (who was thought to be his friend during the time of the video). After saying hi to his brother, SMG4 tells everybody to hide in his room, by using whatever means possible to get them in there so they aren't seen by Kevin.
Once they are all in his room, SMG4 spends a while blocking the door. They have a talk, SMG4 saying it's good and he's fine, Kevin just nodding right as noises from the room become audible. Toad escapes from the room and says hello, SMG4 thinking to disguise him as a talking plush. Toad starts insulting right as SMG4 decides to throw him back into the room. Kevin, confused, just says he was here to pick something up, and says goodbye. SMG4 tells them once he gets back in the room that they aren't meant to be there, so they should stop messing around, Bowser tells him they won't and that he's just jealous of their sexiness. SMG4 gives in and lets them mess around, on the condition that they keep themselves hidden from the public view.
Mario and Luigi go to watching the TV, which they watch Hotel Mario on, both confused. The Shy Guy goes back to the toaster, while Bowser tries to propose to Peach via karaoke, which fails, and Waluigi bothers SMG4 while he's eating. Toad, the Old Man Hobo and Po are outside having a miniature tea party. Luigi comes out and notices the trio, who quickly start acting "into character" and act crazy.
Much later, SMG4 asks Mario how he got there, Mario only remembering the events at the beginning of the video. SMG4 realizes it's something to do with Project64 and Mario says he tried to turn it off but it went "cuckoo crazy" as he refers to the portal. SMG4 decides to try something as he opens the program. He tells Mario to stand back, and does a few things as the portal opens. The two grin at each other, as Mario is held inside the portal by SMG4. Mario proceeds to scare many citizens (some from popular videos) and does this repeatedly for a long time. SMG4 decides he's had enough and throws Mario back out, as he lands at the wall with a bra. SMG4 is confused, as Mario tries to explain himself. Mario almost jumps back in, SMG4 grabbing him right as Mario sees the castle and ponders what he'll do. SMG4 decides to get everybody only to find they're causing chaos in his street. He decides there's only one thing to do, and dances, which attracts them all and he leads them to his room again.
After a short goodbye, SMG4 leads them to the portal, and soon only Mario is left. SMG4 says goodbye, then Mario says goodbye as well, but only calls him "an asian guy he doesn't know", due to him not believing SMG4 in the beginning. SMG4 is then relieved he doesn't have to deal with them again and walks out. Suddenly, Steve then became revealed to have come through and didn't get sent back, and starts typing on the keyboard as the portal reopens. SMG4 stands out on his porch when suddenly the portal brings the entire castle into the real world, crushing everything around his house. SMG4 facepalms, and the episode ends.
After the credits play SMG4 is shown to wonder what he's doing with his life. At the very end it is revealed this blooper is "brought to you by Old Man Body Lotion".

- In the video thumbnail, Mario and the gang are standing behind SMG4's real life self in his house.
- This is SMG4's longest blooper since Ssenmodnar 2, from October 2012.
- This blooper is considered his 200th video, however, it's his 199th video technically available. This is because the video "WELCOME TO SMG4'S MAGICAL LAND OF RETARDEDNESS" is currently unlisted and it is unviewable. As a result, YouTube disregards it and it is not included in the total count.
- This is the only video of SMG4's where he only appears as a real person in its entirety.
- This is the third time that we see Lakitu in Garry's Mod, the first being "The Blooper Competition" and the second being "Retarded64: Mario for Hire.".
- This is the second time that we see Peach in a Mario Party 3 model, the first being "SM64 guides: Toadsworth's How to - Princess".
- This is the third time that Mario is talking through voice at the same time and saying the same thing in text. The first time was briefly in the video "Super Happy Magical Fun Fun Island", and the second time was in "A SM64 parody: Number 1 (Bob-omb battlefield remix)".
- Kevin refers to SMG4 as "Luke". This confirms his name, which was revealed previously as "Luke Lerdwichagul", to be true.
- A similar video to this is The Adventures of Mario and Luigi - Ep. 4 where voice is used.
- The Error Screen on the computer says "SSSMMMMOOOKKKKEEEE WWWEEEDDD EEEVVERY DAY"
- There is a hidden Patrick Star plush
- As Mario talks to SMG4 you can see Kevin on the computer screen in one part.
- Toad was for the most part voiced by Marhfg in this blooper.
- When Rocks flies into the portal, his left half is still stuck in it at the end. Also, Luigi still has a shocked face when he goes into the portal.
- When Waluigi rushes into the bathroom, he is then shown in the family room spazzing out on the couch. It is unknown how he got there.
- During the scene where the guy punches the computer, the date at the bottom says 2006. This doesn't make sense, since the blooper was made in 2014.
- When Luigi tries explaining to Luke what he was watching, Wario disappears from the latter's bed.
- Steve can be seen in the thumbnail for the video as though he was with the other characters, but he isn't seen in the video until the very end, after everyone leaves.
