An unusual situation in the park

We needed to write a story with the following sentence: "Sue was walking in the past, when something unusual happened." Here you have my production.

Sue was walking in the park, when something unusual happened. She was looking at the little red thing next to the lake. When she was getting near, she saw that the red thing was shivering. While she was getting nearer and nearer, she was looking things clearer. Sue was shocked. It was the last thing she expected to see there, a little girl.

She ran to help the kid. It was an 8-year-old girl with black short curly hair, blue eyes, pale skin and a beautiful dress covered with blood.
I didn't have to ask her name. She was Sophie Aggrest, princess of Foxen.
