Go to the old house in etena forest at night and go into the room with the tv and talk to it.
yes but giratina, shaymin and rottom special forms will not appear
Rotom can be caught in the Old Chateau (In the forest north of Floaroma Town). To get it to appear you need to go to the tv inside the Chateau at night and inspect it.
