Ep 26. Scare at the Litwick Mansion!

Ash and his friends arrive in a new town, where they hear stories about a haunted mansion that is home to Litwick, a ghost-type Pokemon. The group is intrigued and decides to investigate the mansion, where they meet a researcher named Professor Icarus. He tells them about the history of the mansion and the Litwick that reside there.

As they explore the mansion, strange things start happening, and they realize that it is indeed haunted. The Litwick lead the group through the mansion, and they soon come across a room where a family portrait hangs on the wall. Professor Icarus explains that the family in the picture used to reside in the mansion, but they disappeared a long time ago, leaving behind their Litwick.

Suddenly, the group is attacked by a group of Gastly and Haunter, who seem to be possessed by some kind of dark power. The Litwick come to their rescue and use their fire attacks to drive away the ghosts. The group then discovers that the dark power is coming from a powerful Pokemon called Chandelure, who resides in the mansion's basement.

Professor Icarus explains that Chandelure is using the Gastly and Haunter to create fear in the Litwick, which it then feeds on to become even stronger. The group decides to put a stop to Chandelure's plans and heads down to the basement to face it in battle.

After a tough battle, Ash and Pikachu are eventually able to defeat Chandelure, causing the dark power to dissipate and freeing the Gastly and Haunter from its control. The Litwick also become free from their fear and happily dance around the group.

Before leaving the mansion, Professor Icarus thanks the group for their help and gives them a special Litwick for their journey. Ash and his friends bid farewell to the Litwick and head off to their next adventure.
