    "I hate green beans!"
    — Jeffy

    Jeffy Jeffy François, simply referred to as Jeffy (born 21st August 2004), is one of the main characters of the SuperMarioLogan series. He is the adoptive son of Mario and Rosalina. The character was created by Logan Thirtyacre and Elaina Keyes. He is voiced by Lance Thirtyacre. He first appeared in the SuperMarioLogan episode "Mario The Babysitter!".

    Why He Really Is a Bad Boy Indeed that Deserves to Eat Green Beans

    1. The most frequent criticism of Jeffy's character is that his portrayal relies on him being uncontrollable, rowdy, destructive, and purposely obnoxious lout with little depth beyond that, with his repetitive outbursts generally being considered more tiring and grating to watch than amusing once they lose their novelty. Not helping is that he tends to recycle the same limited pool of jokes; he cries, throws swearing fits, destroys property for little or sometimes no given reason other than the fact that the SuperMarioLogan writers clearly wanted it to happen and be the way, annoys Mario, or in the newer videos, unfunny stock catchphrases, to the point where his character becomes repetitive and monotonous. Many specialized examples of criticized moments are:
      • "Jeffy's Bad Word!": Arguably the worst of the bunch, Jeffy repeated the homophobic F-slur nonstop, accused Mario of rape, and got him hated on a global scale all because he justifiably spanked him for saying the aforementioned slur!
      • "Locked Out!": He wasted his peas, acts like a brat at dinner, and most notoriously, locks Mario out of his house and even gets him arrested because he wouldn't let him eat chocolate cake.
      • "Jeffy's Tantrum": He throws the TV off the balcony and later the couch and throws a massive meltdown because Mario wouldn't let him purchase SpongeBob Moves In!. He even went so far as to actually attempt suicide by hanging himself all because he can't get a single $3 game. (though to be fair it was also Mario's fault because he was being a cheapskate for not buying a simple $2.99 SpongeBob SquarePants game from the App Store.) That is how you express anger, right?
      • "Robot Jeffy": Gets Jeffo to replace him to do his daily antics then causes him to go into kill mode by Bully Bill which results in cutting school, breaking the dishes and almost killing Mario, Junior, and Cody.
      • "Jeffy's Wi-Fi Problem": He breaks a bunch of dishes mindlessly and drops some vases on the floor.
      • "Jeffy Gets Hypnotized!": He throws the house TV in the lake for absolutely no reason and later goes to throw a boombox.
      • Any time Jeffy does anything bad, he barely gets punished for it, and never learns his lesson, especially when Rosalina is present, as she enables his rowdy and oftentimes dangerous behavior and occasionally even encourages it, (with the obvious exception of "Among Us"), or Brooklyn T. Guy wanting something from Jeffy in exchange of him letting Jeffy off with a warning instead of taking Jeffy into jail, hence making him a huge Idiot Houdini.
    2. As an extension of the above, during 2016-2018, he would often even repeat the same lines over and over such as "Why?", "I don't even know.", "Why would you do that?", "I didn't have to!", "I didn't like that!", "You say Jeffy's a bad boy?", and probably the worst of the bunch, "Oh, si papi!', which get stale and repetitive fast.
    3. With that said, many of his other recurring jokes aren't all that funny and can be considered rather cringe-worthy:
      • When he was first introduced, there used to be a nauseating running gag of him soiling himself and sometimes even going as far as to stick his hands in it and sniff it ("Jeffy's Mistake"). Thankfully, these jokes mostly got phased out of the series as it went on.
      • He used to frequently spank his crotch; a joke that generally serves little purpose other than to pad out the runtime.
      • Jokes revolving around the pencil stuck in his nose.
      • Sticking his "pee pee" into various objects, most commonly Cheerios boxes.
      • He is known to drag out a video with filler. There is also the beginning of "Jeffy Gets Hypnotized", where he makes Mario try to spell "uhh".
    4. He is/was a very clear and obvious disabled stereotype (at least in his debut year), which has been a major source of his controversy.
      • While Logan has stated multiple times that Jeffy is not disabled and is supposed to be just "stupid" in a manner like Chef Poo Poo or even Mama Luigi from early SuperMarioLogan. This has been contradicted several times in the series, notably in "Jeffy's Stupid Home Video!" where he is directly called mentally disabled by Brooklyn Guy, and "Bowser Junior Kinda Goes Camping" where Jeffy says "I'm down... syndrome."
      • Though granted, he has become a much less obvious stereotype after his debut.
    5. He is an insanely unintelligent character who has shown a complete lack of common sense to the point that it's incredibly unfunny and instead is incredibly irritating and frustrating to watch, enough to make the flanderized versions of Patrick Star in seasons 6-9a of SpongeBob SquarePants, Billy, Stimpy and Sheen Estevez look like Dipper Pines (and granduncle Ford Pines), Rick Sanchez, Tony Stark/Iron Man, the Tom Holland's/Marvel Cinematic Universe version of Peter Parker/Spider-Man, Sheldon Cooper, Ezekiel Zick and Data (Star Trek: The Next Generation) in comparison to him.
      • A good example of his idiocy is the reason he gives for wearing his diaper on the outside of his pants; so, it doesn't get dirty, although the pants are still going to get dirty and could still give him a rash, something several characters in the series have pointed out.
    6. He cries frequently over stupid stuff and for no good reason, especially in his older appearancesHe's shown to be unable to accept criticism, as whenever someone calls him a bad boy, he'll start crying, wailing, and banging his head onto something.
    7. He was also notably flanderized in 2017 and 2018, often cited as his worst years by viewers, as most of his jokes, especially his swearing, his idiocy, and his tantrums were taken up to eleven. The flanderization combined with him starting to hog the spotlight from the other characters (including Mario, the channel namesake), was a major factor in the perceived loss of quality as a majority of videos in that period were simply him doing the same tired, predictable jokes ad nauseum with few other characters to break up the monotony.
      • It got to the point that Jeffy's frequently shoehorned into videos for little purpose other than driving up views and videos that have little/nothing to do with him are named after him for the same reason (ex: "Jeffy's Paper Shredder").
      • In fact, Logan has rehashed Junior videos, but with Jeffy in them, possibly just pleasing his fanbase. This is because the SML fans almost only watch the channel to see Jeffy.
      • Because of this, he's a great example of the worst traits of cash cow characters.
      • When Mario calls out for him when he does anything bad, Jeffy, instead of crying, yells "ARE YOU FUCKING HIGH?!".
    8. He has a very ugly and creepy yet iconic character design (although he was created by Beacon Art Studios by Eva Gronowitz from Etsy and not by Logan; the same person also made the original Jeffy that is used in Logan's videos, and he is still very unappealing to look at).
    9. While his voice is good for the most part, he can sound shrill and annoying and like Fred Luckpuig on drugs at times, especially when he is shouting, whining, yelling, and screeching.
    10. He fails to have proper character development for a few reasons:
      • Jeffy's titled videos do not guarantee him as the main character and only a catalyst for a different plot that has little to do with him.
      • He never keeps his words or promises to Mario or anyone else. Two examples include "Jeffy's Parents" (where he promised to be a good boy) and "Jeffy and the Beanstalk" (where he promised to eat his green beans).
    11. He is insane as he deliberately hurt himself in "Jeffy's Green Bean Allergy!" all over not eating cookies. His parents also straight up tell him this fact!
    12. He can count as a Gary Stu in 2016-2018.
    13. He is shown to be dishonorable to people's deaths when he disrespects Bone Crusher's death by attacking his corpse in Jeffy's The Wrestler.
    14. He is extremely immature as he never acts his age. As of 2022, he is considered to be a man-child as he's 19. He is an adult, but he still acts like a child and has the mentality of a toddler, even his parents mention this to him, but he doesn't want to listen.
    15. He's a pathetic punching bag as he is shown to be either a coward or incompetent, such as:
      • In "Drawing Jeffy", he stupidly gets himself framed by Drawing Jeffy for bothering Mario.
      • He stupidly allows Rosalina to remorselessly abuse him most of the time.
        • Also for some reason, he didn't even acknowledge that even Rosalina abuses him, making him much more pathetic.
      • In "Jeffy the Rapper!", he almost got himself killed by Toad using a gun to attempt a murder on him which ended his first rap career. Not only that but before that, he also used the n-word!
    16. Similar to Joseph starting with 2021, Jeffy can be seen as a filler character from time to time, especially when there are videos here and there when he hogs the episodes spotlight.

    Good Boy Qualities that Deserve Chocolate Cake

    1. It is understandable why Jeffy is the way he is. His prostitute mother, Nancy, was very abusive to him, he never got a proper education, he saw his sister get run over, and he currently lives with a mother who enables all of his bad behavior and a father who quite understandably is overly strict and barely even cares about him.
      • Rosalina is also very abusive to him which shows why he misbehaves even more to the point he becomes dehumanized into becoming insane.
    2. He and Rosalina got their greatest comeuppance in "Among Us" through their ways, on Jeffy's side, he got killed by Chef Pee Pee's impostor, and on Rosalina's side, she got ejected out from the house after Bowser Junior, Brooklyn Guy, and Chef Pee Pee's imposter thought she killed Jeffy. And they were extremely well deserved.
    3. Some of Jeffy's commonly criticized character traits do have reasonable justifications, such as his hatred of green beans. While Jeffy's hatred for green beans is often used for obnoxious and repetitive jokes, he is right in that Mario never tries to feed him anything else that's healthy, despite Jeffy having been shown to like other healthy foods like carrots.
    4. He has been the star of some great and memorable SML videos like "Jeffy's Homework", "Jeffy The Rapper (and its sequel), & "Jeffy Ball Z 1-4".
    5. Unlike Cody, he can stand up for himself, most notably when Bully Bill called him a retard in Jeffy gets bullied.
    6. Although he is nowhere near a good role model, and while on the topic of that video, he teaches many good lessons that kids could learn from (although they still shouldn't copy him) most notably dealing with bullies.
    7. He can be reasonable out of his sheer idiocy.
      • One example is the surprisingly clever running gag of him bullying his wannabe bully, Bully Bill.
      • In fact, some of his other jokes (like the swearing) were fairly amusing at first and only became worse because they were beaten into the ground.
      • He tends to be funnier when he's paired with Junior (ex: "Jeffy And Junior Skip School", "Jeffy and Junior's Big Heist", and "Jeffy and Junior Go To Prison")
        • In Jeffy's Bad Christmas, he hilariously throws the Christmas tree out of the window.
        • In Cody's Report Card, while a filler in that episode, he throws the desk at Jackie Chu.
        • He is surprisingly good at bowling with a blindfold on as shown in "Jeffy Goes Bowling".
        • He has some hilariously good quotes, such as "Christmas? It's March, bitch!" in "Jeffy's Tantrum" or "When something goes bad, there's always good." in "Jeffy and Junior's Big Heist".
    8. He is surprisingly very strong as he can beat up Bully Bill; he is also strong while he is an infant, as seen in "Baby Jeffy".
    9. His design is very fitting for his character considering him not being that well written.
    10. He has notably improved as of 2019, as he isn't as obnoxious as he was in 2016-2018, even if it's nowhere near enough to justify his rather controversial reputation.
      1. He is likable in the Jeffy Ball Z and Five Nights at Freddy's series where he is protective of Marvin and his friends, and the spinoff, SML Gaming, where his stupidness and angry moments are toned down (similar to Joseph and Junior).
    11. As mentioned above, Lance Thirtyacre mostly does a good job voicing him and he gives the character a fitting voice (at least when he's not yelling or whining).
    12. Due to being a pathetic punching bag to Rosalina, he actually has a right to be against her at times as a callback for her abuse and dehumanizing him such as how he says that nobody likes her.
    13. He's extremely talented at drawing.
      • In fact, he uses magic words to make his works of art come to life.
    14. Unlike Rosalina, he and Junior were able to help out with the aliens (consisting of the Alien, his wife, and Baba-Booey) escape from the CIA.


    Jeffy has proven numerous times to have been the most controversial character of SuperMarioLogan. Many fans criticized him, saying that he was an offensive stereotype of mentally disabled people. Logan has responded to these claims by saying that Jeffy is meant to be funny like Chef Poo Poo, not mentally disabled.

    After "Jeffy's Bad Word!" and "Locked Out" were released, Jeffy received immense hatred from older fans, due to him saying the F slur multiple times and being an absolute jerk towards Mario. Despite this, he is also known to have a diehard fanbase, which consists of children and young teenagers, adding even more controversy. After Jeffy's Parents!, fans started to sympathize and like him even more as he had been abused by his mother, Nancy. However, some fans still hate Jeffy.

    Jeffy's popularity grew when "Jeffy The Rapper!" and "Jeffy's Fidget Spinner!" were released, which made many young children grow fond of Jeffy and worship him. Later, the children constantly demanded more videos featuring him and would dislike any video that did not feature him. This caused many older fans to fuel their hatred for both Jeffy and his fanbase. In "Jeffy's Fun Day!," he received a poor reception.

    In December 2017, a seven-year-old boy attempted to hang himself with a noose the way Jeffy almost did in his emo form in the now-deleted "Jeffy's Tantrum!" The mother of the child discovered this and reported it in The Sun newspaper after he attempted to do the act. The article can be viewed here. Logan then apologized and assured that his videos were not to be imitated; despite this, YouTube started demonetizing and age-restricting all of his videos. A few months later, some second graders and third graders watched "Jeffy The Rapper!" and were disciplined after mimicking him (mostly by boys).

    In late 2018 and early 2019, SML lost many of its viewers since Jeffy became incredibly overused and popular with young children, even though his actions and language were inappropriate for their age. Jeffy's overuse came at the expense of other classic characters such as Woody, Shrek, and Mr. Pig, as younger fans began outnumbering the older fans and pressuring Logan to make more Jeffy videos, to the point that videos where Jeffy didn't appear such as Toad's Mistake! (2017) and Attack of the Killer Shrimp! were panned by younger viewers simply because neither had Jeffy in them at all. During the break-up drama in 2020, it was revealed that Chilly Jimenez had pressured Logan to push Jeffy.

    Jeffy's popularity is now such that Logan can no longer write out or kill off Jeffy without losing most of his subscribers; worse still is that Logan's address is public knowledge, and his getting rid of Jeffy would put himself and his family and friends in danger of being attacked by Jeffy fans.

    However, now that Jeffy has toned down his swearing and acting inappropriately, no one seems to hate him as much and started to enjoy him more. But that's not to say that people no longer hate him, as there are still some people who do, mainly SuperMarioPlush Parody because he no longer likes Jeffy; he only likes 2016-17 Jeffy. He even made TikTok videos saying that Jeffy needs to move out or needs to go back to his old personality.
