Jim and Andy walk along the beach, looking for adventure. They joked that one day they would find a talking fish or a mermaid or a bottle with a treasure map in it. So far, they have only found shells, rocks and seaweed. But today is different. The boys are excited. Sea crabs are jumping on the rocks. One side goes up and the other side goes down. They are fast and lively. The tide never seems to wash them away. Then Jim saw a fish. It ran aground on the beach and just flopped about. "Can it talk?" Andy asked. "It looks like any other fish," said Jim. He picked it up gently and took it to the water. "Do you think it will satisfy any of our wishes?" Andy smiled. The boys watched the silver fish quickly cross the water. "No. Maybe next time. " Jim grinned. When the two friends walked further on the beach, they found a bottle. It is green and has a cork in its mouth. "Our luck will change. Is there a map or an elf in it? " Andy joked. Andy reached for the bottle. He rubbed it. Nothing happened. He pulled off the cork. Nothing happened. He shook it. Nothing happened. "Try the cork again. I bet the monster is waiting for us to release him. Or we'll find a treasure map and have a real adventure, "Jim shouted. Andy pulled the cork again. He swung it back and forth. He twisted it round and round. Finally, it popped up without breaking. A boy shook the bottle. Nothing came out. Looking inside, he can't see anything. Jim looked at it too and shook his head. Empty. "It's just an old wine bottle," Jim complained. He grabbed the bottle and threw it back to the beach. The bottle hit a rock and broke into pieces. Andy and Jim gasped when they saw a long silver key on the ground among the broken glass. They looked at each other. Why don't they make a sound when they shake the bottle? Why didn't they see it? Andy bent down to pick up the key. Suddenly, the pieces of glass got together and formed a bottle. The key mysteriously returned to it! The bottle began to roll slowly towards the sea. ...
