Write a short story (< 3 paragraphs) about a knight saving a frog princess.  Write it for kids.
Once upon a time, there was a brave knight named Sir Hop-a-Lot. He was known for his courage and his love for adventure. One day, while he was wandering in the forest, he heard a strange noise. He followed the sound and found a beautiful frog princess who was crying for help. She had been captured by an evil witch who wanted to turn her into a potion.

Sir Hop-a-Lot knew he had to save the frog princess. He fought bravely against the witch and her minions and finally defeated them. The frog princess was so grateful that she gave Sir Hop-a-Lot a magical amulet that would protect him from all harm. From that day on, Sir Hop-a-Lot wore the amulet everywhere he went and continued to have many more adventures.
