Once upon a time, in a land far, far away, there was a little girl named Lily. Now, Lily loved to tell jokes and make everyone laugh. She had a contagious giggle, and her smile could brighten up even the gloomiest days. One sunny afternoon, Lily's mom took her to the zoo. They strolled past the lions roaring, the monkeys swinging, and the elephants trumpeting. But there was one animal Lily was really excited to see – the penguins!

As they approached the penguin exhibit, Lily noticed something strange. One penguin was waddling around all by himself. His name was Percy, and he looked quite upset. Lily walked up to Percy and asked, "Why are you so sad, Mr. Penguin?"

Percy sighed and said, "I lost my funny bone! Penguins need them to tell jokes and make everyone laugh, and it's nowhere to be found!" Lily couldn't help but feel sorry for Percy. She thought for a moment and said, "Don't worry, Mr. Penguin. I have a plan! Let's search for your funny bone together!"

Percy's eyes lit up with hope, and they began their hilarious adventure. They looked high and low, under rocks and behind bushes, even in the penguin pool, but no funny bone. It seemed like Percy's sense of humor had vanished completely. Just when they were about to give up, Lily spotted something shiny near the ice cream stand. It was round, white, and had a big red heart painted on it. "Is this your funny bone, Mr. Penguin?" she exclaimed.

Percy was overjoyed! He put it on and immediately started bouncing around, making the funniest noises. Giggles filled the air, and everyone at the zoo couldn't help but crack up. As they strolled back to the penguin exhibit, Lily and Percy were like a comedy duo, telling jokes and making people laugh all the way. Even the monkeys started doing somersaults, and the lions couldn't stop roaring with laughter.

From that day forward, Percy became the funniest penguin in the whole zoo, thanks to Lily and her incredible knack for finding funny bones! Lily's mom smiled as they settled into bed that night, knowing her daughter's heart was filled with laughter and joy. She leaned down and whispered, "Sweet dreams, Lily. May your life always be as funny and bright as it was today."

And with that, Lily closed her eyes, clutching her favorite joke book tightly, ready to dream of new adventures filled with laughs and giggles galore.
