"We are not un-happy about" the response, said Julie Wenger, senior director of U.S. marketing for McDonald's(MCD, Fortune 500). "Happy is not for everyone. He's about having fun. Really for kids and families."
Wenger said: "Happy is promoting healthy choices through fun and lightheartedness."

@samkamani said, "In order to fight obesity in kids, McDonalds introduces its new mascot to scare children."
@erikbransteen said, "Congrats #McDonalds, first you fatten our kids, then you haunt their nightmares."
