"Ghost Jeffy!" is the 410th episode of SML Movies.
Jeffy is a ghost and Mario needs Luigi's help to save him!
Jeffy wants to eat some Lifesaver Mints "Booby Candy", but Mario says he will choke on them and gives him some Lifesaver Gummies instead. While Jeffy is choking on them, Mario's phone rings.
It's Luigi on the phone and he says he's coming to Mario's house in about 3 minutes. Mario says he needs to be better than his brother so he tells Jeffy to hide, but he died from choking on the gummies. Mario quickly calls the doctor. The doctor comes in and tells Mario that Jeffy is dead. Mario suggests him that he does CPR but he doesn't not want because that is "gay'. Brooklyn T. Guy asks how he died what Mario responds that he might have choked on a lifesaver. Brooklyn T. Guy mistakes it for a "lifesaber" but Mario corrects him and shows him the gummies lifesaver candy. Brooklyn T. Guy and Mario try to think about the situation (while Brooklyn T. Guy makes a fourth wall joke) but then, Jeffy comes back as a ghost! He is confused and asks what is the kid on the couch doing (his body). Brooklyn T. Guy says that he can't do much about this and leaves screaming like a girl.
Mario tries to explain to Jeffy that he died and now he is a ghost. Jeffy asks if he is a scary ghost and then yells Boo multiple times before finally stopping. The doorbell rings and Mario tells Jeffy to hide and he does that while Mario goes to answer it, and it is his brother Luigi. They have a shirt talk for a while (along with roasting each other) and then Mario tells Luigi to come inside. Luigi talks to Mario about his couch but only to find out that he has a son (adopted) Jeffy. Mario tells him he is not his son and he is adopted. Mario and Luigi then have another roast talk about their games until Luigi mentions that he sucks up ghosts. Mario Alerted tells Luigi he needs help and Jeffy is actually dead. Luigi terrified asks that he is dead and Mario responds yes and husband ghost is around the house somewhere and he needs his help catching it. Luigi says that he scared of his ghosts but Mario convinces him over his fear and they get Luigi's vacuum.
Luigi and Mario then go to Jeffy's room to see I feel he is there (while Luigi's tells Mario a little bit more about his vacuum) they look every where but don't find him so they try outside. Mario thinks he knows where he could be hiding and leads him to a cheerio box (Jeffy's favourite food). They take off the box and Jeffy was hiding there the whole time. Mario tells Luigi to suck him up but Luigi starts crying saying that he I saw scared of ghosts but Mario eventually convinces him again and he sucks up Jeffy's ghost. Luigi happy asks Mario who is number 1 he says that it is still Mario himself Luigi says that he will release Jeffy but Mario changes his mind and they go to the machine to release Jeffy's ghost.
At the machine, Luigi tells Mario to put Jeffy's body in the machine. He does that and then Luigi uses his vacuum to out Jeffy's ghost inside. They turn on the machine and then Jeffy comes out saying uh multiple times in Mario's face. Luigi asks if he is ok but Mario tells him that that is him. Mario tells Jeffy to say hi to his uncle Luigi and he does but mispronunces it. Mario thanks Luigi for coming over and saving Jeffy and Luigi says anytime if he needs help. Luigi is then about to leave says thanks to Mario for helping him getting over his fear of ghosts and Mario thanks him again and (breaking the fourth wall) if Jeffy would have died forever the channel would have been gone. Luigi and Mario then roast again about their channels and then Luigi leaves saying "bye!" and the video ends.
- This is Luigi's and Kamek's first appearance since The Perfect Plan! although Kamek's appearance was a background cameo.
- It's revealed that Brooklyn. T. Guy is a necrophiliac.
- The ghost Jeffy puppet is the same puppet used for the depressed Jeffy.
- This video marks the first time that Luigi meets Jeffy.
- The plot of this video is very similar to the previous video except Jeffy is in Poopy Butt's role and becomes a ghost rather than becoming evil.
- The thumbnail uses the same background from Cody The Vampire!
- Mario claims that Lifesavers candy can make someone choke, but there actually holes in the middle of the candies, which are meant to keep the consumer from choking, explaining why the candy is called Lifesavers. However, Mario likely does not know this or was more than likely done for irony as hinted at in the video.
