Once upon a time there lived a mother goat with her children. One day she had to go out and told her daughters not to open the door
Oh, my poor belly! I have to look for food
After saying goodbye to their mother, the goats went to her room to play.
Great, they look tasty!
Meanwhile, a black wolf was sleeping in the forest. The previous day she couldn't catch anything to eat.
Little kids, it's your mother, open the door!
When the wolf woke up her stomach began to growl and it hurt so much that she howled. So she set out to find some prey to eat.
The wolf had no energy to hunt and was about to give up until she saw a house, when she approached the window she could see the goats playing in her room, she began to drool and, when she heard a goat saying her mom was out she had an idea.
In this way, the wolf pretended to be the mother of the goats, calling them to open the door.
