Once upon a time, in a cozy little house by the sea, lived a boy named Santi. He had a secret talent that no one else had - Santi could see into the depths of the ocean. Every time he gazed into the water, the sea life below was as clear as if he were swimming alongside.

One sunny morning, Santi went to the beach with his yellow bucket. The waves rolled in, and he squinted his eyes. There! He spotted colourful fish darting among the rocks.

As he watched the fish, a tiny crab scuttled to the surface. "Are you lost?" Santi asked. The crab waved its claws, as if trying to speak. Santi understood it needed to find its family.

Santi decided to help. He scanned the ocean floor and saw a group of crabs dancing in the sand. "There they are," he said. He gently scooped the little crab up and placed it back in the ocean.

The little crab joined the dance, and Santi felt a burst of joy in his heart. He loved helping his ocean friends. Just then, he noticed something strange. A dark shape moved in the distance.

"What could that be?" Santi whispered. He tried to see clearly, but it was too far away. He needed to help but felt a little scared. With a deep breath, he decided to come back tomorrow with his binoculars.

The next day, Santi returned with his trusty binoculars. He searched through the waves until he found the shadow again. This time, it was clearer - it was a dolphin caught in a fishing net!

Santi knew he had to act fast. He ran to get the lifeguard and explained what he saw. The lifeguard followed Santi, and together they set out on a rescue boat.

Approaching the dolphin, the lifeguard carefully cut the net. The dolphin swam free, jumping out of the water as if saying thank you. Santi's heart swelled with happiness.

Word got out about Santi's special gift. People from the village came to him when they lost something in the water or when they spotted sea animals in need.

Santi became the ocean's guardian, using his vision for good. He helped many creatures, big and small, and taught others to take care of the sea. Santi's love for the ocean grew even more.

Now, when Santi looks into the sea, he doesn't just see fish or crabs; he sees friends. And he knew, in his heart, that he would always protect his underwater world.
