Julian Jay Jimenez, or simply known as JJ, is Chilly and Tito Jimenez's younger brother. He used to appear in most of Chilly's vlogs, but since he is at school, he doesn't have the time to interact with the vlog. He has since moved in to Logan's house, with his siblings. Today, he is one of the main production assistants in SuperMarioLogan, but hasn't had any direct appearances yet. Overtime, he has helped the cast with big projects, such as covering the house with tinfoil for Bowser Junior Goes To The Future!, and he was the one who did the scream for Areola in Jeffy's New Toy!. He is currently a junior at Tate High School (where Logan and the SML crew attended), and plays soccer there. He is also very talented at basketball, and he has a passion for it.
