The friends were filled with a sense of relief and satisfaction as they returned the replica treasure to the museum. They were glad to have made things right and to have the support of the judge and their community.

But as they were leaving the museum, they noticed a strange man lurking in the shadows. He seemed to be watching them closely. The friends were immediately on guard, remembering their previous encounter with the thieves who had stolen the map.

They quickly made their way back to their homes, but the strange man seemed to be following them. They decided to split up and take different routes, hoping to lose him. But the man was persistent and continued to follow them.

Feeling uneasy, the friends decided to meet up at their secret hideout in the woods. They needed to figure out who this man was and why he was following them. As they discussed their options, they heard a knock on the door.

Cautiously, they opened the door to find the strange man standing there. He introduced himself as Captain Blackbeard, the infamous pirate who had once owned the lost treasure of Pirate Island. He had been watching the friends and was impressed by their bravery and determination.

Captain Blackbeard explained that he had been searching for the treasure for years, but had never been able to find it. He had heard about the friends' adventure and wanted to offer them a deal. He would help them find the real treasure of Pirate Island, and in return, they would get to keep a portion of the treasure for themselves.

The friends were hesitant at first, not wanting to get involved in another treasure hunt. But they also couldn't resist the opportunity to go on another adventure with Captain Blackbeard. They agreed to his offer and set off on their journey.

With Captain Blackbeard's knowledge and the friends' skills, they were able to find the real treasure of Pirate Island. It was even more magnificent than they could have imagined. They were overjoyed and grateful to have been a part of such an incredible discovery.

As they returned home with their newfound treasure, the friends couldn't help but reflect on their journey. They had learned valuable lessons about responsibility, teamwork, and the importance of doing the right thing. And they knew that their friendship would only grow stronger with each new adventure they embarked on. The end.
