In a house that smelled like toast and sunshine, lived a girl named Hannah. Her bedroom was a magical land of its own, with glittery unicorn posters on the walls and a big, fluffy rug that looked like a soft white cloud. Hannah loved to keep her special world tidy, and today she was carefully lining up her pencils to make a perfect rainbow on her desk.

Suddenly, a little sound floated in from the hallway. It was a sad sniffle, followed by a quiet sob. Hannah peeked out her door and saw her little brother, Leo, sitting on the floor with his favourite red toy car. One of its wheels had fallen off. "It's broken," Leo whispered, a big tear rolling down his cheek. "It can't zoom-zoom anymore."

"Don't you worry, Leo," Hannah said, her helpful heart taking over. "I can fix it!" She dashed to her craft box and pulled out a roll of sticky tape. She wrapped the tape around and around the little axle and pushed the wheel back on. "There!" she said proudly. But when she gave the car a little push, it went... vroom... wobble... plonk! The wheel fell right off again. Leo's face crumpled, and Hannah felt a prickle of frustration.

Hannah looked around her room, searching for an idea. Her eyes landed on her favourite poster: a beautiful unicorn with a horn that sparkled with rainbow magic. That was it! Not magic, but imagination! "I have a unicorn idea!" she declared. She grabbed her tub of colourful playdough, scooped out a blob of sparkly blue, and squished it firmly where the wheel should go. She pressed the wheel into the playdough and held it tight. "Ready?" she asked Leo. She gave the car a push. Vroom, vroom, ZOOOM! It raced all the way down the hall!

Leo's sad face disappeared, replaced by a giant, sunny grin. "Wow! You fixed it! It's a magic rainbow car now!" he squealed, giving Hannah the biggest, squeeziest hug. A warm, happy feeling spread through Hannah's chest, just like a rainbow after the rain. She knew that helping wasn't always easy, but using your imagination could solve almost any problem. That night, she dreamt she was flying on a unicorn, racing rainbow cars across a starry sky.
