At the hunted house you could catch Rotom as said, just go up the stairs and through the door in the back (has to be at night) to the left of the very first door in sight the middle door, there will be a room with a tv in it, if at night time it will say: it feels as if a Pokemon is staring at u, do u wish to shake the tv? say yes and u will battle rotom
I couldn't find any door decorations that scream but there are a lot of variations of spooky door hangings. You could always put a movement activated scream machine near the door to scare your Halloween visitors.
They stop at a partly hidden door, turn the key and push it open with an appropriately spooky creak.

The Pokemon Rotom can only be found at night, by entering the spooky mansion in Eterna Forest, going up the stairs, and then entering the middle door. Find the door that leads to the room with the TV, then walk up to it and press A. The game will tell you that there is a Pokemon hiding in the TV, and then it will ask you if you would like to thump it. Say yes and Rotom will appear.
