-Ignoring both Black Ogres and the Cat to see if something else would pop up on the map. Nothing. It's so weird that they don't really attack you though.
-Luring one of the early Ghosts outside of the main entrance and letting it hop around. Nothing, but at least it got to enjoy the sunlight.
-Luring some nearby Ghosts to the big Yellow Ghost to see if it might eat them and turn into something different. It just sits there otherwise.
-Getting the cat into a fight. I'd fight and run from the purple ghosts nearest to the room until we were all inside of the room, and then try to attack the cat with an area attack. It just ignored everybody and then got spooked like normal if Ajna ran close.
-Bringing the first Ogre into the other building, to see if his rolling around might mess with something. I could manage to bring him through the courtyard, but he'd usually kill me (from running too much) just as we'd get through the entrance. Plenty of fights in the courtyard with no effect. I was able to escort a few of those Ahps across the courtyard to the other building though, and they got to hang out with their friends.
