Once upon a time, there was a cheerful fish named Bob. Bob liked to pick up little stones from the sea floor. One day, he saw a big, dark shadow in the water. Bob did not know what it was, but he felt scared.
Bob swam fast to his friend, Sally the sea turtle. He told her about the big shadow. Sally knew that it was a shark. She told Bob to be careful and stay near the rocks, so the shark could not find him. Bob listened to Sally and hid in the rocks.
Later, the shark swam close to the rocks. He was looking for a fish to eat. But Bob was safe in his hiding spot. The shark could not see him. Bob was so happy that he had listened to Sally. From that day on, Bob and Sally were the best of friends. They played together and picked up stones, always staying close to the rocks.
