This is a story of Mama Goat and her kids who used to live happily. Until one day, a wolf noticed the kids. When Mama Goat was going to buy food for her kids, she told their kids to be careful. The wolf was so clever that he painted himself white and changed his voice. In no time, the kids opened the door. He ate six little goats one by one and left the seventh one because his belly was full.
