Jeffy

"UH!"

- At random occasions repeatedly

"ARE YOU FUCKING HIGH?!"

- Jeffy's catchphrase whenever he is angry

Jeffy Jeffy-François, known simply as Jeffy, is the tritagonist of the SuperMarioLogan franchise. Known for being a foul mouthed, ill-behaved, idiotic, perverted young teenager with an unusual personality and a strange choice of clothing. He is the adoptive son of Mario and his wife Rosalina.

History
Jeffy was born in a porta-potty at 7 Jeffy Street in Paris, France, on August 21, 2004 to Nancy and Jacques Pierre François. Nancy, a prostitute, was very abusive towards Jeffy for unknown reasons. At some point in his life, Jeffy moved to the United States with his mother and possibly his father. Jeffy was then dropped off at Mario and Bowser's apartment because his mother was tired of his antics. Jeffy lived with Mario and his family in the apartment (causing havoc around the house, especially towards Mario) before being evicted from the apartment and having to relocate to the new house. After his wealthy father committed suicide and willed his money to Jeffy, Nancy returned to reclaim Jeffy in order to receive Jacque's money. After Nancy was arrested for child abuse, prostitution, and much more, Mario chose to officially adopt Jeffy as his son. Jeffy then resumed living with Mario, and continued to cause much mischief around the house.

Appearance
Jeffy is somewhat taller than the average teen, with a lanky and short posture. He wears a blue bicycle helmet, usually has a pencil shoved up his nose, along with a yellow t-shirt that says "Jeffy," his name, on it. He wears short dark blue jeans with a diaper outside of it, which he occasionally spanks. According to Jeffy, the diaper is on the outside of his pants so the diaper doesn't get dirty. Jeffy wears black Adidas sneakers. His biological appearance seems to be 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 has a round nose, along with two eyelashes and a unibrow.

Personality
Jeffy has displayed acts that can be seen as outright idiotic. He has a bad habit of spanking his diaper placed outside of his pants. When he is called a "bad boy," he tends to have a meltdown by throwing his head onto any surface, but calms down when he is called a "good boy" (but this doesn't happen after the episode Jeffy Loses His Pencil!). However, he could have even more of a breakdown, by swearing and being rude towards Mario and Rosalina. He likes to put his "pee-pee" in various objects, especially Cheerios cereal boxes. He is also afraid of the most retarded things such as animals, toilets, snow, ostriches, and the flu shot. His mother delivered him to Mario because she did not want to look after him (according to Jeffy). Not much is known about his relationship between Bowser Junior and Joseph, despite the fact that they both called him "awesome" after once surviving a game of "Russian Roulette." Rosalina is more loving and caring towards Jeffy to the point where she acts like a motherly figure and calling Mario off whenever he gets angry at Jeffy. However, Jeffy has been shown to act smart, but in a dumb 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. Later, in Jeffy's Bedtime!, he called I-Am-Sam, the tall character in Green Eggs and Ham, a liar since he claimed that he liked the green eggs and ham, but the illustration clearly shows that he didn't eat the ham at all, and, despite suffering from mental retardation, Jeffy is an extremely skilled painter, result of his former father being a famous painter. According to him, he used to live on 7 Jeffy Street before being dropped off at Mario's door. Jeffy tends to soil his pants often. Sometimes, Jeffy can be even more demanding than Junior, as seen in Jeffy's Bedtime!, where he demands that Mario and Rosalina make his green eggs and ham, in "Jeffy Gets Potty Trained!", and when he demands that Rosalina give him marshmallows instead of peas, in "The Hitman!", where he wanted Jello after Mario gave him green beans, he refused to eat his McChicken Nuggets because he wasn't given 20 toys and threw them away, and finally in "Locked Out", where he demanded for chocolate cake, cried when Mario didn't give him it, and locked Mario out to enjoy the cake, especially in front of Mario. 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. Sometimes Jeffy seems to have a prankster personality as in "Jeffy's Cellphone!", where he prank calls several places, including an employee named Josh, and in "Shrek The Babysitter!", where he locks Shrek in the bathroom with the help of Junior. During both of these videos, 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 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.

Early Prototype
Early Jeffy looks very different from the Jeffy puppet used in SML's videos. Unlike Jeffy, Early Jeffy's eyes are shaped more like a real person's and they appear to be black or brown instead of blue. His shirt is a plain yellow shirt that does not have the words "Jeffy" written on it. His hair and eyebrows are brown, It also shows that Jeffy used to have eyebrows at one point. Early Jeffy wears jeans without a diaper on the outside. However, this was later confirmed to be a forgotten character, Timmy (Human).

Sick Jeffy
Sick Jeffy is Jeffy with the flu, taking way greater effect than normal would with other characters such as Mario, and having a chance of giving others the flu. His appearance also changes to rundown, tired, and overall extremely droopy. The puppet was made by a fan. This version of Jeffy appeared in Jeffy's Flu Shot!.

Smart Jeffy
Smart Jeffy is a variation of Jeffy, appearing in an episode of the same name, who is incredibly smart compared to his normal form, due to his pencil having impaled his brain because of a freak accident indirectly caused by Junior. However, at the end of the video, Jeffy sneezed, blowing his pencil out back down his nose, leaving a hole in his brain, and reverting him to his normal form.

J-Fee
A rapper variation of Jeffy that sings the songs "Why?" and "Wanna See My Pencil?."He has gotten arrested twice; the first time for shooting an elderly woman and opening up somebody's mail, the second time for slapping a girl. This version of Jeffy appeared in Jeffy The Rapper!.

Emo Jeffy
Emo Jeffy is a more depressed version of Jeffy with goth-looking clothing and hair. This variant appeared in Jeffy's Tantrum!.

Green Bean Jeffy
Due to the Green Bean Giant being angry at for not eating green beans, he cursed Jeffy and transformed him into a human-size green bean. The curse eventually wore off after Jeffy ate a whole plate of green beans, reverting him to his normal state. This is the primary reason why Jeffy no longer complains about green beans until Jeffy’s Cat Piano Problem. This variant appeared in Jeffy And The Beanstalk!.

Banana Jeffy
Due to the fact that Jeffy has a yellow butterfly in his stomach, he turned into a banana. After Mario and Does Bad Things Guy, who was thought as Brooklyn Guy at that time, escaped from the banana (Jeffy), Does Bad Things Guy injected Banana Jeffy with a banana to human serum, which can turn any banana back into a human.

Redneck Jeffy
Redneck Jeffy is a variation of Jeffy with a Redneck brain in his skull. After Jeffy sneezed his brain out, the doctor accidentally dropped his brain in his recycled brain bin, and they had to spent 8 hours picking out random brains, one of the brains was the Redneck brain. He wears a Mexican hat, rattles a Cha Cha, and talks in a Southern accent. This version of Jeffy appeared in Jeffy's Brain!.

Drawing/Play-Doh Jeffy
Drawing Jeffy is a clone of Jeffy that he accidentally created by saying "Doodle doodle pencil fart!". Junior traps him into a piece of paper, and he is not seen until Jeffy Sneaks Out!, where Jeffy accidentally revives him with Play-Doh. He is shot and killed by Mario. This is the only variation of Jeffy that has had the most appearances. The puppet for this version was made by a fan.

Jeffy App Salesman
Although not a form or variation of Jeffy, it is an identical person, looking and talking exactly like him, aside from wearing Marx glasses. This version of Jeffy appeared in Jeffy's Tantrum!.

Angry Jeffy
Jeffy turns way more angry than usual after eating tic-tacs. He gets so mad that he even shouts at Junior, who is one of his best friends. It looks like the normal Jeffy, but with big slanted eyebrows. He appears in Jeffy Gets Help!.

Depressed Jeffy
Jeffy's face gets really messed up, similar to Drawing Jeffy. However, he is black and white, and wants to kill himself. This form's Jeffy isn't energetic like his normal self. This happened after eating tic-tacs. The puppet for this version of Jeffy was made by a fan. He appears  in  Jeffy Gets Help!.

Hallucination Jeffy
Jeffy turns into this form after eating tic-tacs. Its appearance is the same as the normal Jeffy, but he hallucinates and mistakes people as animals, similarly to the premise of Schizophrenia Case Study. He mistaked Mario as a lion, Rosalina as a camel and Brooklyn T. Guy as a chicken. This version of Jeffy  appears only in  Jeffy Gets Help!.

Wig Jeffy
Jeffy has lots of overgrown "hair" that needs to be cut. After Mario sees him, he goes to call a haircutter to cut Jeffy's 'hair'. When he starts to cut it, it reveals that it's actually a wig.

Mario
Mario is Jeffy's adoptive father. Mario has an apparent strong dislike of Jeffy, but deep down, he loves him. This is pretty much confirmed in Jeffy's Parents! However, Jeffy likes Mario. usually calls Mario "Daddy". Mario finally adopted Jeffy after a year in Jeffy's Parents! Mario was incredibly unhappy that Jeffy was dropped off at his apartment door and loathes the fact he has custody of Jeffy. Mario gets frustrated within nearly every video they appear in together. Most of the time, however, it seems that Jeffy annoys Mario, not on purpose. Mario has tried multiple times to get rid of Jeffy, but to avail. Most of his attempts ended with Jeffy back at Mario's step or in the case of Where's Jeffy?, Mario going back to get Jeffy because he had Rosalina's necklace, only to find out that gave it to a squirrel. In Bowser Junior's Nerf War!, both Mario and Jeffy even made a small cameo appearance right at the end and Mario attacked Jeffy with a Nerf gun. Jeffy gets Mario into trouble often. Although Mario gets annoyed with Jeffy most of the time, he has been shown to care about Jeffy, as shown in Jeffy's Mistake! when Black Yoshi was about to kill Jeffy; in Rosalina's Parents!, Mario gets scared when he assumes Jeffy fell to his death and freaks out when Jeffy gets abducted. It's possible Mario might only care just so Rosalina won't break up with him. Despite all this, they deep down love each other and can't live without one another.

Rosalina
Jeffy and Rosalina seem to get along well, especially on Rosalina's side. She 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. He will yell at her occassionally if he does not get his way.

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

Nancy
Jeffy's mom, whose name is Nancy, debuted in Jeffy's Parents!, and she was shown to be very abusive towards him, to a much higher extent than Mario was. Nancy acted like 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.

Jacques Pierre François
Not much is known about Jeffy's relationship with his dad, world-renowned French painter Jacques Pierre François, who had died 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.

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 the exact same traits. They can even communicate to each other through diaper patting, somehow. However, because she has, so far, only appeared in Jeffy's dream, some speculate that because she was not dropped off along with Jeffy, Feebee either possibly never had been dropped off, never existed in the first place, or may probably be even dead.

Brooklyn T. Guy
Most of the time, the Brooklyn 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. However, in the third episode of Who Wants To Be A Millionaire?, Brooklyn Guy is shown to get annoyed with Jeffy's behavior.

Chef Pee Pee
Jeffy seems to like Chef Pee Pee. Chef Pee Pee, however, does not seem to have patience for Jeffy, almost as much as Mario; 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 ruined the pencil cake Chef Pee Pee made for him in Jeffy's Birthday!.

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 on the bathroom with the toilet clogged.

Bully Bill
Jeffy is a frequent target for Bully Bill. However, Jeffy does not taking it lying down, and often brutally beats him in retaliation. Despite the amount of beatings he has taken, Bully Bill never learns his lesson.
