Jeffy Jeffy, or simply referred to as Jeffy, is the tritagonist of the SuperMarioLogan franchise and YouTube channel. He is extremely funny and talks about poop and diarrhoea sometimes.
He is the adoptive son of Mario and Rosalina.
He is the oldest child of Nancy and Jacques Pierre François, and the older brother of Feebee, but since Jacques died and Nancy went to jail in Jeffy's Parents!, as well as the death of his younger sister, he is now the adoptive son of Mario and his wife, Rosalina.
He is the secondary antagonist in Season 8, and the main antagonist in Jeffy's Tantrum!, Jeffy Plays Fortnite!, and his debut episode Mario the Babysitter! Despite being an antagonist in these episodes, he is the main protagonist in some SML episodes, such as Detective Jeffy!, Jeffy's Parents!, Jeffy Gets Bullied!, and Jeffy's Bad Christmas.
Since his debut, Jeffy has proven to be very popular, most particularly with younger fans. Despite his popularity, he has also caused much trouble and controversy and is overwhelmingly unpopular with many older SML fans.
Jeffy is somewhat different than the average teen, with a tall 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 whould 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 a point of losing 100,000,000 dollars because of it.
Jeffy always poops his pants which made Bowser Junior write “Poopy Butt” on his shirt. Once his pencil got taken out and then he became really smart, in “Smart Jeffy”, where Jeffy’s pencil is seen stuck in Jeffy’s brain which made him act very dumb all the time. He also gets grounded a lot, mainly when he says something gross, swears or do something wrong. His favourite toy is his cat piano, which he does random stuff with it. He hates the vegetable green beans and always shakes them, throws them at the wall and even bury them in the backyard
He wears short dark blue jeans with a 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.
