Once upon a time, on a mysterious night, moonlight illuminated a quiet forest. In this forest lived four special cats: Luna, Shadow, Simba, and Whisk. Each cat had unique characteristics: Luna had bright eyes that always shone in the night; Shadow enjoyed wandering in the shade, never liking to be exposed to the sunlight; Simba was a brave leader, always leading the other animals to explore the mysteries of the forest; and Whisk was known for its long whiskers, always staying vigilant.
