The Old Chateu (chateu means mansion in french) is a haunted mansion that's falling into despair after being abandoned by it's owner, and that has ghost pokemon. If you head into the dining room, you'll see a male ghost. (I think he's the ghost of the owner) He'll float away. Also, if you head to the room next to the last room to the right, you'll see a girl ghost. (I think she's the ghost of the owner's daughter) She'll float away too. If you have the National Pokedex and if it's nightime, that's your chance too catch Rotom. It is known as the ghost of the Old Chateu. If you defeat Rotom, don't panic. Rotom will reappear the next evening. WARNING!!! If you defeat it again it will NEVER reappear again so be careful. Note: The Old Chateu has spooky music so you might want to put mute on your Nintendo DS. (same thing in Newmoon Island,Spring Path, and Turnback Cave)
near the end of eterna forest
the old chateu is only in Pokemon diamond pearl and platinum versions
i dont think you can i suggest you get gastly and evolve it
No, the only way to get Gengar is to trade a Haunter.
just walk in the rooms and i guess that she will eventually come.
Ghost,at least that what everybody says
there r 2 good places to get ghost Pokemon on Pokemon diamond: the old chateu in eterna forest and the lost tower by solaceon town
she is seriously a ghost so you can necer talk to her not even with cheat codes.
Have a gba Pokemon game inserted and go to the old chateu, then go to the room with the T.V. in it and press the A button.
Go up to the screen and tap A. Remember, it has to be after 8 o'clock for Rotom to show up.
In Eterna Forest.
It Is In Eterna Forest At The End
