What happens when you eat 3 green Christmas tree cookies?

You get green poop. Mason helped me make cookies for school with bright green icing. He had green icing from his head to his toes, but it was fun. He consumed three cookies, one that I gave him and two that he helped himself to without me knowing. The next day when he went to the bathroom it was very interesting to say the least. I'll just post a picture of the cookie and not the after effects. (this cookie is a few days old so it's a little smashed)
