Jeffy Jeffy Pierre François, (or simply referred to as Jeffy), is one of main characters of the SuperMarioLogan  series. 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 and Scooter, but since his biological father Jacques died and Nancy went to prison in "Jeffy's Parents!", he and Scooter are now the adoptive children of Mario and his wife, Rosalina.[7][8] Despite this, he still has his younger cloned brother, Scooter, who is currently wandering around outside Mario's house somewhere.

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. (check out sml wiki for more info)
