Jo Jo, a Gungan, was among the offspring of Jar Jar Binks, specifically one of three. Subsequent to the collapse of the Jedi Order, Darth Vader experienced a crash landing on Naboo; it was at this time that Jar Jar Binks met him and presented his children: Jo Jo, Jay Jay and Jee Jee. Displaying their exuberance, the children then jumped upon the Sith Lord and proceeded to adorn his armor with crayon markings.
