Who Is Mikey's First Friend?

Jon found Mikey in his bedroom, reading one of his comic books. "Are you ready to go to the mall?" Jon asked him. "Mom had to go to work, so I'm gonna take you instead." His little brother put down his comic book. "You're gonna pick up the rest of my friends too, right?" "Of course," Jon said. His brother stood up from his bed and left his room, then followed Jon downstairs and out of the house. After getting into the car, Mikey told Jon where to go first.
