Main

Jeffy Jeffy François, is a student at Y U DUMB? Elementary School, and the adoptive son of Mario and Rosalina. Jeffy is the biological son of the painter Jacques Pierre François and Nancy. During his childhood, Jeffy suffered abuse, lack of parenting and education and trauma as he lost his sister at a young age.

Jeffy was first revealed in Mario the Babysitter! with absolutely no memory of what he went through during his childhood. Overtime, Mario would develop hatred against Jeffy for all the stress and trouble he has caused him. Jeffy acts like a mentally disabled kid for three reasons; his mother was very drunk during her pregnancy with him. He was never enrolled in a school due to lack of responsibility; he was always beaten by his biological mother.

Jeffy was then put on a two-month hiatus for an undisclosed reason, returning in Bowser Junior's Game Night 3. Meeting Junior for the first time and developing a good relationship with him along with Joseph and Cody, who later becomes best friends within the future.

In attempt to put an end to Jeffy's existence. Mario hires a bounty hunter/hitman to kill him once and for all and to get him out of his life. Mario then lures Jeffy to the park with an ice cream cone but at the last minute, Jeffy threw the ice cream cone away leaving Patrick to die by accident.

Jeffy's behavior however is worse, as Mario was taking him to the store, Jeffy is rapidly saying the f word (f*ggot) in front of people. This causes Mario to react on impulse and beats Jeffy in front of Rosalina, this causes Jeffy to call the police and Mario is fired from Nintendo, and he is known to the world as the "Worst Parent Ever".

In 2017, the truth about Jeffy is revealed as in "Jeffy's Parents!" Mario gets a call from the office explaining that they found Jeffy's biological mother and he is taken away. Mario excited, Rosalina decides to break up with him. Jeffy then escapes from the grasp of his mother and runs back to Mario's house. Learning where he came from, resisting Nancy's wrath. Mario calls the police and has Nancy arrested, Brooklyn Guy comes back with a note saying that Jacques Pierre François was his biological father, realizing that he was a famous painter who made millions of money deemed that Jeffy will inherit the money his father made on Sunday, August 21, 2022.

Jeffy then promises that he will be a good boy and he wants to stay with Mario to avoid being placed in a foster home. Mario and Jeffy decide to start their first episode as a official Father and Son as Mario decided to adopt him officially.

Set a few months after "The New House!". Jeffy was playing Hide and Seek with Mario and Rosalina. And Jeffy was overhearing knocking/banging from the Secret Door and opened the door to be traumatized to twenty-six dead bodies, about to be killed by Does Bad Things Guy, they were then rescued by Brooklyn T. Guy revealing that he was on vacation for seven-months.

He is the oldest child of Nancy and Jacques Pierre François, and the older brother of Feebee and his adopted clone brother Scooter, but since his biological father Jacques died and Nancy was arrested he and Scooter are now the adoptive children of Mario and his wife, Rosalina.[7][8] The things that he does in his everyday life is annoying and torturing Mario, hanging out with Junior and his friends, causing trouble, hating school, throwing a plate of green beans, eating chocolate cake and more.

Personality

Starting off as a mentally disabled baby-like kid before evolving into a slightly ditzy person who swears like a sailor, explodes in anger at any slight against him, and knowing a lot about perverted acts for someone his age, Jeffy's personality has gone through more changes than any other character. Over time, he has matured and does not annoy Mario and Rosalina as much as he used to. He rarely swears anymore and only acts more like a troublesome child. He is also known to be very strong, possibly one of the strongest characters in SML, as he tends to beat up bullies, hit balls really hard, and has a high pain tolerance.

He has a habit of spanking his diaper placed outside of his pants as well as soiling his pants often. When he is called a "bad boy" or in some cases a "retard", he tends to have a breakdown by throwing his head onto any surface but calms down when he is called a "good boy". his breakdowns can become extreme and violent, which involves curse words and being rude towards Mario and Rosalina. He also flips his desk in "First Day Of School!" because the teacher assigned a 10-page essay that was due the next day and cusses (mostly the F-word) at Jackie Chu, saying "ARE YOU F**KING HIGH?!" He often says "Why?" whenever someone tells him what to do or what not to do. He even keeps saying it whenever someone answers him. He also has a habit of calling things he likes "pee-pee." He also often says "I don't even know" when asked questions.

He likes to put his "pee-pee" in various objects, especially Cheerios boxes, to the point where he somehow even impregnates one and develops romantic feelings for it. He deeply resents Bully Bill, who picks on him and subsequently beats up all the time, but the person he hates even more is his teacher, Jackie Chu, his archrival and most hated person in the world.

He is also afraid of trivial and ridiculous things, such as animals, toilets, snow, ostriches, a flu shot, and the number 7. Based on characteristics, it is suggested that he has mental retardation. His mother delivered him to Mario because she did not love him for unknown reasons (according to Jeffy).

Despite not being very smart, Jeffy has shown traits of intelligence, but in a retarded way at times, such as in "Jeffy's Homework!" when he reasoned that the equation 8-4=8, since they are taking 4 out of the equation, even going on a profanity-laced rant as well as getting very smart over the years as Mario thinks he will not notice anything or remember anything but he does so he is not very dumb anymore. He is also an extremely skilled painter, a trait passed down from his father. He has also shown signs of intelligence as in "Jeffy Gets Ran Over!", where he remembers everything that happened to him after getting knocked out by Mario's car, as well as knowing that Mario is the one that hit him.

Jeffy has shown to be demanding, even more than the level Junior displays, as seen in "Jeffy's Bedtime!", where he demands that Mario and Rosalina make his green eggs and ham, "Jeffy Gets Potty Trained!" when he demands that Rosalina give him marshmallows instead of peas, "The Hitman!", where he wanted Jello after Mario gave him green beans, he refused to eat his McDonald's Chicken Nuggets because he wasn't given 20 toys and threw them away, in "Locked Out", where he demanded chocolate cake, cried when Mario didn't give him it and locked Mario out to enjoy the cake, especially in front of Mario, and in "Jeffy Gets Help", when Jeffy yells, screams, and throws a temper tantrum because Mario said that he would not watch SpongeBob SquarePants.

Jeffy is shown to enjoy playing pranks, as seen in "Jeffy's Cellphone!", where he prank calls several places, including an employee named Josh and a prostitute, resulting Rosalina thinking Mario is cheating and beating on Mario, and in "Shrek The Babysitter!", where he locks Shrek in the bathroom with the help of Bowser Junior. Both of these videos shows that he seems to be less unintelligent, causing many fans to think that this could be a normal version of Jeffy, despite all of his intelligent moments in the series. Some people [who?] think Jeffy pretends to be retarded. When his real mother Nancy tried to claim him back, Jeffy begged Mario to let him stay and promised to be a good boy (and kept his promise by not playing the cat piano when he went back inside), indicating that he loves Mario very much. Jeffy's obsession with swearing may be from his mother and the way she acted in front of him and treated him.

Despite of all this, he is generally more on the friendly side and the bad things he does are mostly due to his unintelligence. He has his fair share of good deeds that battle the evil ones, such as being considerate of to Hansel in three episodes. He is most likely misunderstood after suffering pain from his biological mother and witnessing his twin sister and biological father's death, which might explain his outburst problems.

Although he is unintelligent, he was shown to be an adult to Mario in some episodes such as the time when he caught Mario spilling water all over his bed and Mario wanting to play with his Lego rather than eating his food. And sometimes he does not like to believe people like in "The Halloween Heist!".

Appearance

Jeffy is somewhat different than the average teen, with a tall and slim posture. He wears a blue bicycle helmet (with black messy hair under it), usually has a pencil shoved up his nose, has blue crossed eyes, along with a yellow T-shirt that reads "Jeffy" on it which his mother wrote so he would not forget his name. Apparently, when a different word is written on it he thinks his name is that word as seen in "Jeffy's Shirt!" when Junior wrote “poopy butt” on it. Jeffy thought it was his actual name to the point of losing 100,000,000 dollars because of it.

He wears short dark blue jeans with a Pamper diaper (which, according to Jeffy himself, is on the outside so it doesn't get dirty), which he occasionally spanks. He wears black Adidas sneakers. His biological appearance seems to be mixed between his parents, with his blue eyes inherited from his mother and his dark brown hair inherited from his father. His face is oval shaped with two teeth and around the nose, along with two eyelashes and a unibrow.

Early Life

Troubled Childhood

Jeffy was born as Jeffy Jeffy François in a porta-potty at 7 Jeffy Street, Paris, France, on August 21, 2004, to prostitute Nancy Pierre François and painter Jacques Pierre François. They are both of French descent, but Jacques is full-blooded French. Due to not being raised properly, as well as being abused by his mother, he acts really dumb and even still wears a diaper over his pants. His mother also forced him to stick a pencil in his nose for unknown reasons. He also lost his toes through an unknown incident. This was seen in "Jeffy Breaks His Leg!".

Jeffy moved to Florida in 2005 with Feebee, his little sister, who later died in a bike accident as Nancy took her helmet to use as an ashtray. Her death was the reason why Jeffy always wears his helmet wherever he goes.

Abandoned by Nancy

After Nancy had enough of his antics, Jeffy was dropped off at Mario and Bowser's apartment. Jeffy lived with Mario and his family in the apartment (Causing havoc around the house, especially towards Mario), although the latter hated him before being evicted from the apartment and having to relocate to the new house.

The Death Of His Sister

In 2015, Jeffy was trying to teach Feebee how to ride a bike, and while Feebee was not good at it, she never gave up and kept trying, but due to Nancy using her helmet as a tray. Feebee was unable to survive being hit by a truck going at least 60 MPH. Jeffy horrified after the death of his sister, decided to keep his helmet on at all times.

Inheritance of his father's money

After his wealthy father committed suicide and willed his money to Jeffy, Nancy returned to reclaim Jeffy in order to receive Jacques' money when Jeffy turns 18, but was arrested and incarcerated for child abuse, prostitution, and several other crimes. After Nancy's arrest, Mario chose to officially adopt Jeffy as his son and the two now begin to bond every day.

Rapper Career

Inspired by what Tyrone has sung. Jeffy decides to become a rapper and instantly was successful but due to Tyrone's bad influence. Jeffy is convinced that because he is a rapper, he can start committing crimes to get more famous. He first assaults a woman, opens a mailbox and shoots a elder, earning him months in prison.

Toad over seeing how successful Jeffy has become decided to make a diss track on Jeffy, which quickly spreads word around the world. Jeffy intended to fire back but instead gets a message from Toad asking for him to step outside so they can finish this.

Jeffy walking outside at night trying to find Toad at the designated location he mentioned in the message is interrupted when Toad pulls up and shoots Jeffy mutiple times. Luckly Jeffy survived his wounds and decided to not be a rapper anymore.

The Cloning Situation

Jeffy currently has two clones. Drawing Jeffy and Scooter. During 2018, Mario and Rosalina constantly fall for the switch with Jeffy and Drawing Jeffy. In "Jeffy's Clone!". Jeffy is cloned by Bowser Junior and Cody by the C-C-Cloning Machine.

Scooter is currently lurking outside Mario's house and it is unknown if he is still alive or not. He is very well presumably deceased, and Jeffy and Mario haven't heard of mentioned from him since his last appearance in "Rich Scooter!".

The Christmas Crisis

During "Jeffy's Bad Christmas". Jeffy is greeted to only one present on Christmas morning and it is full of coal revealing that Jeffy did not make it on Santa's nice list. Jeffy reacting on impulse throws the tree outside destroying it.

Jeffy then meets up with Junior and Cody and turns out Cody has a device that can bring Santa to their reality. Jeffy at first knocks out Santa without context. Next, Jeffy is convinced by Santa that he will not run the next time but somehow, he teleported to the front of the house and knocked out Santa yet again.

The final time, Santa finally comes up with a master trick and tricks Jeffy, Junior and Cody that if they turn around and count to 10, they will each get as many presents as they want. The trio falls for this and Santa makes his great escape. Jeffy saddened that he will not get any presents this year. Junior decides to give him one of his presents.

Status: Neutral

Bowser Junior

Jeffy with Bowser Junior

Considering how widely popular and relevant both characters are, Jeffy and Bowser Junior are very good friends. They enjoy hanging out with each other and make a good team.

When Jeffy and Junior met for the first time in Bowser Junior's Game Night 3, Junior called Jeffy awesome for surviving a game of Russian Roulette. Jeffy was indirectly also the reason for Mario and Junior permanently recognizing each other starting from that episode, and he also seems to like Junior. As of recently, both Junior and Jeffy seem to get along more, as shown in Shrek The Babysitter! and Smart Jeffy. Junior even caused the main plot elements of Smart Jeffy and Jeffy Loses His Teeth!, wherein he made a jump from a trampoline and hit a table in the former, and accidentally knocked one of Jeffy's teeth out with a T-ball bat in the latter. However, Jeffy and Junior have had major conflicts between each other in the past, such as Junior being responsible for the death of Jeffy's children Puss Hole and Puss Hole 2 in Jeffy's Kids!, a deleted video. Despite this, they generally seem to be on a good term regardless. After Jeffy and Junior skip school, where Jeffy agreed with junior to skip school to go mini golfing. He and Junior are now best friends to a point where junior plays with him more than Cody and Joseph. In Jeffy and Junior's Big Heist, Jeffy helped Junior retrieve Charleyyy’s underwear and getting him to sign it as they both disguised as people from corporate to make him sign it. He and Junior are now best friends.

Status: Best Friends

Cody

Cody and Jeffy are good friends. Although sometimes Jeffy can get on Cody's nerves, Cody doesn't mind this. Cody finds Jeffy extremely stupid as seen in The Test! when he fails to teach Jeffy proper math. Along with Bowser Junior. Cody sometimes finds opportunities to rape Jeffy, it is unknown if Cody was able to rape Jeffy in The Remote! as Cody sometimes find's Jeffy attractive.

Status: Neutral

Nancy

Debuting in Jeffy's Parents!, Nancy is shown to be very abusive towards her son, to a much higher extent than Mario was. Nancy acted as she cared about him when people were around, but when they were alone, she would always beat him. Nancy eventually got arrested and Jeffy ended up getting adopted by Mario.

Nancy then returned in "Jeffy and Junior Go To Prison!". Jeffy was placed in a cell with her, and Nancy threatens him that she is going to kill him and get her money. Jeffy then corrected her saying instead of serving a few years. She will serve life in prison as Nancy does not have custody of Jeffy anymore as of 2017.

Nancy returned once again in "Jeffy's 17th Birthday!" and breaks out of jail. She tracks down Jeffy at his house and knocks out Mario and holds him at gunpoint where Brooklyn Guy tried to reason with her. Guy then explained that he was only turning 17 and that he would receive his money next year and Nacy then realizes her mistakes and comes willingly promising that she will break out next year.

Status: Enemies

Rosalina

Jeffy and Rosalina seem to get along well, going to where Rosalina copies Jeffy a lot. Jeffy usually calls Rosalina "Mommy" just like how he calls Mario "Daddy." Rosalina acts like a deep motherly figure to Jeffy, to the point of sometimes caring more about Jeffy, and calling Mario out whenever he abuses Jeffy, even breaking up with Mario when he heartlessly let Jeffy go with Nancy. She most likely does this as she wants to be the mother Jeffy was “supposed“ to have as Nancy abused him which makes Rosalina mad as she absolutely hates to a point at even trying to break up with Mario as he tried to give Jeffy back to Nancy. He will yell at her occasionally if he does not get his way, but despite this, He mostly loves her as a mother. Rosalina is more loving and caring towards Jeffy to the point where she acts as a motherly figure and calling Mario off whenever he gets angry at Jeffy.

Status: Neutral

Jacques Pierre François

Not much is known about Jeffy's relationship with his dad, world-renowned French painter Jacques Pierre François, who had passed away after committing suicide in pursuit of his art. Due to the fact that Jeffy's "IF LOST" paper contains Jacques's name and address information, this could imply that Jacques used to care about Jeffy. Jeffy has also claimed that he learned basic French from his father.

Status: Unknown

Feebee

In Jeffy's Sister!, it was revealed that Jeffy has a sister named Feebee. Jeffy and Feebee are very similar in character, with nearly exactly the same traits. They can even communicate with each other through diaper patting. However, it was revealed in Jeffy's Sister Returns!, that Jeffy's sister Feebee was killed when she got hit by a truck while riding a bike and died back in 2015.

Status: Siblings

Brooklyn T. Guy

Most of the time, Brooklyn T. Guy doesn't seem to mind and cares about Jeffy, as shown in episodes such as Mario The Babysitter!, Jeffy's Bad Word!, Jeffy Goes To The Zoo! and Locked Out. But he still likes him as a friend. However, in the third episode of Who Wants To Be A Millionaire?, Brooklyn Guy is shown to get annoyed with Jeffy's behavior and is sometimes Jeffy’s Arch-Rival

Status: Friends

Chef Pee Pee

Jeffy seems to like Chef Pee Pee, but Chef Pee Pee, like Mario, does not seem to have the patience for Jeffy. For instance, he got annoyed with when Mario and he were trying to get to eat his green beans. Chef Pee Pee also seemed upset when Jeffy ruined the pencil cake Chef Pee Pee made for him. When Chef Pee Pee babysat Jeffy, he was so annoyed by Jeffy's shenanigans to point that he was would've killed Jeffy if Mario hadn't showed up in time.

Status: Neutral

Black Yoshi

Jeffy doesn't seem to have much of a relationship with Black Yoshi. The two have only unofficially met in one video Jeffy's Mistake! but the events in that video are a dream. However, Black Yoshi and Jeffy have mentioned each other many times in future episodes, like Jeffy's Piggy Bank! and they seem to rather have more of a positive relationship rather than a negative one.

Status: Neutral

Shrek

Jeffy and Shrek don't seem to have a good relationship because Jeffy locked him in the bathroom and ate his cheesecake along with Bowser Junior so Shrek locked both of them in the bathroom with the toilet clogged.

Status: Enemies

Toad

Jeffy and Toad seem to be rivals when it comes to the rap game, however outside of rapping, for the most part they seem to be on good terms, even if they don't have much interaction outside of rapping.

Status: Neutral

Jeffy is a frequent target for Bully Bill. However, Jeffy does not take it lying down, and turns Bully Bill's bullying on him with extreme physical violence. Despite the number of beatings, he has taken, Bully Bill never learns his lesson because he is an idiot.

Status: Enemies

Bowser

Jeffy and Bowser don't seem to have a good relationship due to how Bowser accidentally gave Jeffy the flu by coughing in his mouth in Jeffy's Flu Shot!, how Bowser acted harshly towards Jeffy in The Competition! and how Bowser mistook the shock collar remote for the TV remote and repeatedly used it, shocking Jeffy and indirectly framing Mario in Jeffy's Punishment!, as well as how Jeffy was paid by Mario to break Bowser's trophy in Jeffy and Junior Sneak Out!. Jeffy, however, did congratulate Bowser when he won Charleyyy's underwear in Jeffy and Junior's Big Heist!, but other after that, for the most part they seem to be on good terms, even if they don't have much interaction with each other.

Status: Neutral

Jackie Chu

Jeffy and Jackie Chu are archenemies. They first met in the First Day Of School!. Jackie Chu never like Jeffy because of his bad behavior and Jeffy hates Jackie Chu because the latter yells at him, kicks him out of class, and makes fun of him by calling him a b**ch. Although the two hated each other all the time, but on extremely rare occasions, they kinda have a good relationship with each other, two examples that have the two being on good terms is in The Baby Project! where Jackie Chu gives Jeffy and Junior an A for killing the baby and in The Science Fair! where he gives Jeffy an A+ for melting crayons on his rainbow popcorn project.

He has also carried many objects much bigger than him such as their home couch and big home tv,s
