Leo sat in his ultra-modern wheelchair and watched visitors to the zoo with fascination. His special wheelchair, equipped with a secret jet engine, was his pride and joy. No one knew about this amazing technology except his little sister Yuna. As a tech-savvy gaming fan, Leo had developed the drive himself — with the support of his parents, who worked as engineers, of course.

On this particular Saturday, the zoo was full of life. Yuna, the two-year-old adventurer, jumped excitedly next to Leo and pointed at every animal she discovered. 'Look Leo! ' , she shouted enthusiastically and pointed at the penguins. Leo smiled. His little sister had a special gift for recognizing the best moments in life.

She suddenly received an emergency call via Leo's self-developed zoo app: A young elephant had broken out of its enclosure and was running around the zoo without orientation. The nurses were very excited. Leo knew immediately that this was a case for his secret abilities.

'Yuna, hold on tight! ' , Leo whispered to his sister. With a clever push of a button, he activated the jet drive of his wheelchair. They rose gently into the air, just high enough to glide over the heads of the astonished visitors. Yuna giggled happily and held on to Leo's shoulders.

From a bird's eye view, they quickly discovered the frightened elephant. He was hiding in a quiet corner of the park. Leo carefully steered his wheelchair closer. “Don't be afraid, little friend,” he said softly. The elephant looked up at them curiously.

With a calm voice and careful movements, Leo managed to gain the elephant's trust. Yuna softly hummed a calming melody, which visibly relaxed the elephant. Together, they led the animal safely back to its enclosure, where the relieved caretakers were already waiting.

The news of Leo's extraordinary rescue operation spread like wildfire through the zoo. But instead of being celebrated as a hero, Leo preferred to fly with Yuna to the tree house, which they together called their secret headquarters.

When she arrived at the tree house, Yuna beamed at her older brother. 'You're the best superhero in the world! ' she said proudly. Leo smiled. 'No, Yuna, we're a team. Without your music, we would never have been able to calm the elephant down so well. '

As they played their favorite games together, Leo thought about how special that day had been. He had learned that true superpowers lay not only in technical inventions or spectacular rescue operations, but also in the ability to help and understand others.

From that day on, Leo and Yuna became the zoo's unofficial protectors. Whenever help was needed, they were there — the boy in a flying wheelchair and his little sister with the magical voice. Together, they proved that real superheroes aren't defined by their equipment, but by their heart and courage to help others.
