Ep 24. A Ghost of a Chance

Ash and his companions head to the Old Chateau, an abandoned mansion that is rumored to be haunted. Upon arriving, they are greeted by a strange woman who warns them to leave, but the group decides to explore the mansion anyway. As they walk through the dark halls, they begin to hear eerie noises and see strange shadows moving around them.

Suddenly, they are confronted by a Ghost-type Pokemon named Gastly, who begins to play pranks on them. The group is initially frightened, but they quickly realize that Gastly is just trying to have some fun. They decide to play along, and soon they are all laughing and having a good time.

However, things take a darker turn when they encounter a group of Haunter and Gengar. These Pokemon are much more malevolent than Gastly, and they begin to attack the group. Ash and his companions must fight their way through the mansion, using all of their skills and Pokemon to defeat the ghostly attackers.

Finally, they reach the heart of the mansion, where they encounter the source of all the haunted activity - a powerful Ghost-type Pokemon known as Rotom. Rotom is angry that the humans have invaded its home, and it attacks the group with all of its might.

Ash and his companions must work together to defeat Rotom, using all of their Pokemon's unique abilities to weaken the ghostly creature. Finally, they succeed in defeating Rotom, and the mansion is freed from its haunted curse.

As they leave the Old Chateau, Ash and his companions reflect on their adventure. They realize that not all Ghost-type Pokemon are evil, and that sometimes even the scariest things can turn out to be a lot of fun.
