Lily and her friends went to the beach with their parents for a summer vacation. They felt excited.

The warm sun shone bright. The sand was soft under their feet. The sound of waves was soothing.

Lily spotted an old boat nearby. 'Let’s go on an adventure!' she said with a big smile.

Her friends Tim and Mia agreed. They all climbed into the boat. It was a little wobbly.

They rowed out into the open sea. Sparkling fish swam under the water, and birds flew above them.

The water was clear blue. Suddenly, Tim saw something shiny floating. It was a golden key.

Mia wondered, 'What does this key open?' The friends felt curious and excited to find out.

They rowed towards a small island ahead. There, they discovered an old chest half-buried in the sand.

The key fit perfectly in the chest’s lock. Inside, they found a map and some shiny coins.

The map showed a treasure trail. 'We should follow the map!' said Lily, and they started their journey.

They followed the trail over dunes and through palm trees. Finally, they reached a hidden cave.

Inside the cave was the real treasure - a box full of gems and a note: 'Friendship is the greatest treasure.'
