One day, the family came home to find their house in a mess. Furniture was overturned, dishes were broken, and there were strange noises coming from the attic. The children were scared and the parents were worried. They didn't know what could have caused all this chaos.

Casper appeared before them, floating in the air with a concerned look on his face. "What happened here?" he asked.

The family explained that they had been having strange occurrences in the house for the past few days. They thought it was just their imagination, but now they were sure something was wrong.

Casper knew exactly what was going on. He had seen a mischievous ghost playing pranks on the family. He promised to help them get rid of the ghost and make their home peaceful again.

The next day, Casper and the family went up to the attic to confront the mischievous ghost. They found him hiding behind some old boxes, giggling to himself. Casper introduced himself and asked the ghost why he was causing trouble for the family.

The ghost explained that he was also a lonely ghost and wanted some attention. He thought playing pranks would make the family notice him. But now, he realized that he was just causing them trouble and felt bad about it.

Casper suggested that the ghost join their group of friends and they could all have fun together. The ghost was hesitant at first, but the family welcomed him with open arms. They all played games and told stories, and the ghost finally felt like he belonged.

From that day on, the family had two friendly ghosts living with them in the mansion. They all became the best of friends and had many adventures together. The house was no longer a lonely place, but a happy home filled with laughter and friendship.

Casper had not only helped the family with their problem, but he had also helped another lonely ghost find a new family. They all lived happily ever after, with Casper and his new ghost friend by their side. The end.
