Jeffy is a very sexy puppet with nice fashion sense with clothing saying
"Jeffy" and having a hand up his butthole. Jeffy likes to become a robot for no apparent reason and shoot laser beams at his father Mario. He also may have anger issues and slight bipolar problems because of the fact that his now dead father fed him green beans everyday for every meal. One day after inhaling his Skecher fumes he suddenly raged and killed his beloved Mario green bean lover. Jeffy is now kidnapped and being raped by Aretta (Thunderthigh29's ex)
