Intro. More than 10 Muggle students will enter the Forbidden Forest by mistake, not knowing that this city is a city of wizards only, and Muggles are prohibited from entering it. They will be arrested by Hagrid and he will take them to Hogwarts for investigation. There they will actually find a girl who was with them at school. Her name is Mimi, but she changed her name and changed her personality completely.
