Once upon a time, in a kingdom surrounded by misty forests and shimmering lakes, there lived a young princess named Clara. She loved exploring the palace gardens, especially the mossy well at the edge of the rose bushes. Her favorite treasure was a tiny golden ball, a gift from her late grandmother, which she tossed and caught for hours. 
One sunny afternoon, Clara playfully threw the ball too high. It bounced off a tree branch and rolled straight into the deep, dark well. “Oh no!” she cried, peering into the water. “How will I ever get it back?” Tears splashed onto her velvet dress as she slumped onto the damp stones.
Suddenly, a croaky voice called out, “Don’t cry, little one. I can help.” From the water emerged a green frog with bulging eyes and speckled skin. Clara gasped but leaned closer as the frog continued, “I’ll fetch your ball… if you promise to let me eat from your plate, drink from your cup, and sleep on your pillow tonight.”
Clara wrinkled her nose. The idea of a frog in her room made her shiver, but she desperately wanted her golden ball. “I promise!” she said quickly. The frog dove into the well and resurfaced moments later, holding the ball in his mouth. Clara snatched it joyfully, then dashed back to the palace without another glance.
That evening, as Clara dined on roasted chicken and honey cakes, a tap-tap-tap echoed at the palace door. The frog hopped into the dining hall, leaving wet footprints on the marble floor. “Princess,” he croaked, “you made a promise. Let me sit beside you.”
Clara’s father, the king, raised an eyebrow. “A royal promise must never be broken,” he said sternly. Reluctantly, Clara allowed the frog to share her meal. He nibbled crumbs from her plate and sipped water from her goblet. After dinner, the frog followed her upstairs and leaped onto her silk pillow. Clara groaned, covering her face with a blanket.
But as moonlight spilled through the window, something magical happened. The frog began to glow, his green skin fading into soft golden light. With a pop!, he transformed into a kind-eyed prince in a velvet cloak. Clara sat up, stunned.
“Thank you for keeping your word,” said the prince. “Long ago, a witch turned me into a frog. Only someone who treated me with kindness—despite my appearance—could break the spell.” He explained that he ruled a neighboring kingdom and had searched for years for a person true enough to help him.
Clara blushed, ashamed of her earlier reluctance. “I’m sorry I judged you by your looks,” she whispered. The prince smiled. “You kept your promise, and that’s what matters.”
The next morning, the prince returned to his kingdom, but he often visited Clara. They became dear friends, exploring the gardens and laughing by the well. Years later, when Clara grew older, the two kingdoms united in celebration of their marriage.
And so, the princess learned that kindness and honesty could unlock the most unexpected wonders—even a friendship with a frog who held a prince’s heart.
