In the YouTube SML series, Jeffy Jeffy is the secondary protagonist and the adoptive son of Marvin and Rose. He spends his day annoyingly and torturing Marvin. He usually wears a blue helmet and a shirt with his name written on it by his mom, so he doesn’t forget his name. To engage in the character you will have to keep a shoved pencil up your nose and a diaper worn outside of your pants.
