The Little Wooden Fish Submarine

In the seaside town of Blue Bay lived three best friends. Twelve-year-old Aiden loved machines and was always trying to understand how things worked. Eleven-year-old Mia was fascinated by history and ancient legends and carried an old notebook filled with stories about the sea. Ten-year-old Noah was the bravest of the three. He loved animals and could always make the others laugh when they were afraid. One summer, they discovered a strange little submarine inside Aiden’s grandfather’s abandoned boathouse. It was only about the size of a small car, and its entire body was made of dark brown wood. Its round front looked like the head of a friendly fish, and two wooden fins stretched from its sides. Even more surprisingly, the brass instruments, glass windows, and old steering wheel inside were still intact. Aiden spent a week repairing its engine, while Mia searched through his grandfather’s old sailing journal. There she found a mysterious sentence: “When the wooden fish swims into the deep blue again, it will find the city forgotten by the sea.” Noah grinned and said, “Then let’s go see what the ocean has forgotten.” They named the little submarine The Little Wooden Fish and quietly set off into the deep sea.

The deeper they traveled, the darker the ocean became. Sunlight slowly disappeared above them, leaving only blue shadows around the submarine. Schools of silver fish flashed past the windows, and a giant sea turtle appeared beside them. Noah waved at it, and strangely, the turtle seemed to understand. It swam ahead of the submarine as though guiding them somewhere. Suddenly, the navigation compass began spinning wildly, and several electronic instruments stopped working. Aiden switched to manual control and soon discovered an enormous underwater canyon that did not appear on any map. Far below, faint blue lights glimmered like stars sleeping in the darkness. Mia quickly opened her notebook and found an old drawing of seven towers beneath a sun. Under the picture were the words: “Aruna, the Last City of the Sea.” According to the legend, more than two thousand years ago, a powerful earthquake and a giant wave had swallowed the entire city in a single night. No explorer had ever found it. The sea turtle swam into a narrow passage in the canyon and turned back toward them. “I think he wants us to follow,” Noah said. They guided The Little Wooden Fish through the rocky opening—and suddenly, a gigantic stone gate appeared before them. Beyond it lay an entire city, silent and untouched for more than two thousand years.

The three children stared through the windows in amazement. Enormous stone columns lined roads covered with coral. Ancient palaces stood beneath forests of waving seaweed, while thousands of colorful fish swam through broken windows and stone arches. In the center of the city rose a great domed building crowned by a crystal glowing with a faint blue light. Mia discovered strange symbols and pictures carved into the surrounding walls. One enormous mural showed three children arriving in a wooden fish-shaped vessel. The three friends fell silent. The vessel in the ancient picture looked almost exactly like their submarine. Before they could understand what it meant, the seabed shook violently. A damaged tower collapsed behind them, blocking the route back to the canyon, and stones began falling from the cliffs above. Aiden checked the controls and discovered that the left propeller had been damaged. They were trapped. Noah wanted to search the city for another exit, while Mia believed the murals might contain clues. Aiden wanted to repair the submarine immediately. For the first time, the three friends argued. Finally, they agreed to work together: Aiden would repair the engine, Noah would take a small underwater exploration vehicle to search for another passage, and Mia would study the ancient carvings inside the domed building.

Inside the dome, Mia found a stone tablet covered with mysterious symbols. She could not read the language, but each group of symbols was accompanied by pictures of the sun, moon, waves, and fish. By comparing the patterns, she slowly understood the message. The tablet was not a treasure map. It was a record of Aruna’s destruction. The people of the city had known that the land beneath them was becoming unstable, so they had built a hidden underwater tunnel that could one day allow visitors to escape. At the same time, Noah followed a group of glowing jellyfish and discovered the entrance to the tunnel. Unfortunately, a huge stone blocked the opening. He contacted Aiden through the radio. “We need the submarine to pull it away!” Aiden had just finished repairing the damaged propeller, but there was a problem: the engine had enough power for only one powerful pull. If they failed, The Little Wooden Fish might never move again. They decided to try. Noah attached a steel cable to the stone. Mia used the symbols on the tablet to guide them toward the safest direction. Aiden pushed the engine to full power. The wooden hull creaked, the cable tightened, and slowly the great stone began to move. Suddenly, water rushed through the opening. The current nearly swept the submarine away, but at that moment the old sea turtle appeared again and swam directly into the newly opened tunnel. Following their mysterious guide, the three children raced through the ancient passage and finally escaped through a cave several miles away from the lost city.

When they returned to Blue Bay, the three friends decided not to reveal the exact location of Aruna. On the final stone tablet, Mia had understood one sentence clearly: “The true discoverer of a city is not the one who owns it, but the one who protects it.” They shared only a few photographs and videos, enough to suggest that a lost city might truly exist somewhere beneath the sea, but they locked its coordinates inside Aiden’s grandfather’s old journal. Aiden repaired The Little Wooden Fish and added new sonar equipment and a mechanical arm. Mia began studying everything they had recorded, hoping that one day she could fully understand the language of Aruna. Noah returned to the harbor every afternoon, searching for the old sea turtle, because he was certain it was no ordinary animal. Several months later, while the three friends were checking the submarine inside the boathouse, a small light on the control panel suddenly began flashing. It was a light they had never seen before. A single blue point appeared on the screen, far out in the deep ocean, sending a slow and repeating signal. Aiden, Mia, and Noah looked at one another and smiled. They all understood the same thing: Aruna might have been only the first secret the ocean had chosen to show them. The next morning, The Little Wooden Fish slipped once more beneath the waves and disappeared toward the unexplored world beyond the map.
