Once upon a time, in a small town called Sunnyville, there lived a little girl named Lily. Lily loved sunny days when she could play outside with her friends. But one day, dark clouds covered the sky, and rain started pouring down. Lily felt disappointed because she couldn't go outside to play.

As Lily sat by the window, watching the raindrops fall, she noticed something magical. A tiny rainbow appeared in her backyard! Excitedly, Lily put on her raincoat and rain boots, ready for an adventure.

Lily followed the rainbow through the wet grass and into the nearby forest. The rain made everything look fresh and green. She could hear the sound of raindrops falling on leaves and birds chirping happily.

As Lily walked deeper into the forest, she stumbled upon a group of animals seeking shelter from the rain. There was a squirrel, a rabbit, and a little bird. They looked sad and wet. Lily felt sorry for them and decided to help.

Lily led the animals to a cozy cave she discovered. They all huddled together, keeping each other warm and dry. They shared stories and laughter, making the rainy day much brighter.
