Cookie is the son of Butters. Cookie had a home, but a friend wanted him so we kept him for her. She never took him, so we still have poncho. He really wasn't claimed by anyone in the family, as he was supposed to leave us. Cookie was orginally named Poncho by the people who were supposed to take him. He never really learned his name. The we started babysitting two little girls. One of them started calling him Cookie and he seemed to like it, so Cookie has become his new name.
