Harold

Harold is Hector's 98th Street School counterpart and a kindergartner who calls Rus "Safety Man"; he was part of a group that the kids mentored. He came to admire Rus after falling off a pile of dirt from a hole that The Diggers were digging, and Rus caught him. The Diggers then told him that Rus cautioned them to contact electrical companies to verify for wires in the ground before starting any dig, leading Harold to see him as a hero. Harold and Rus appear to have the closest relationship between any kindergartner and older kid. In "Call Me Ray", Harold gives Rus a note from his parents asking Rus to walk Harold home from school for a period of time, showing that the two are close enough so that even Harold's parents know and trust Rus. In "Dodgeball City", Harold spends time with Rus listening to him playing his new guitar. When Harold is hit in the face by a dodgeball on purpose (similar to how Rus accidentally hit a young kid in the face with a dodgeball) Rus becomes very angry, dons his "Diaval" clothes and single-handedly and quickly defeats all the fifth-graders in the school. He then walks into the sunset, and a mature, manly voice representing Harold when he’s an adult narrates the conclusion of the episode.
