(Translated)
Field Agent [Redacted]: Thank you for taking the time to do this interview Kurt.
Kurt: Oh, not a problem at all. So, what was it that you wanted to talk to me about?
Field Agent [Redacted]: Do you remember that house that you built?
Kurt: I’ve built a lot of houses, but if you’re referring to the one with the guy who expanded the house without my permission, then yes.
Field Agent [Redacted]: Did you do anything differently while building that house?
Kurt: What, like compared to the other houses I built?
Field Agent [Redacted]: Yes, that’s correct.
Kurt: Uh, I guess it was the first time I worked with Oak on a full scale project. Other than that, I can’t say I did anything differently, no.
Field Agent [Redacted]: Why did you stop building the house?
Kurt: Well, I don’t remember everything, but as I was working on the roof of the house, some guys came up to me and told me that I was building dangerously close to a site. I asked what site it was, but they couldn’t tell me. Come to think of it, the outfit your wearing kind of looks like what they were wearing.
Field Agent [Redacted]: Could we move on with the interview?
Kurt: Of course, of course. They examined the house and told me to relocate it. I’ve had to relocate houses before, it was no big deal.
Field Agent [Redacted]: Were you able to relocate it?
Kurt: Well, when I came back the next day the roof was finished, and on top of it was a giant wooden box. It was clearly done overnight, since the support beams were flimsy as hell, and the coloration of the box didn’t match with the rest of the house at all. It really was an eyesore. I walked into the room to find a room with a big red target and a bow and quiver hung up. The next day I came back, and yet another room had been built.
Field Agent [Redacted]: Do you have any information on how the house disappeared?
Kurt: I just came back one day and the house was gone. Before I knew how the guy put up all of the rooms, it was clearly a rush job, but in the weeks before the house disappeared, the house was big enough to be qualified as a mansion! I don’t know how in the hell he managed to tear down a house that big in just one night.
Field Agent [Redacted]: Well, thank you for your time Kurt.
Kurt: Oh, no, thank you! It’s a pleasure to share such a story!
Two days after the house disappeared, it reappeared within a pocket dimension at Site-18. Two D-Class subjects entered the room, and returned after 18 hours. The subjects had reportedly gotten lost within the “Maze that is that fourth dimensional house.” Further tests were conducted, and it was discovered that the house was not, in fact, fourth dimensional. The following are some of the rooms found when people entered this house:
Dr. Fredrickson: A room containing nothing but clocks
Dr. Y——: A room containing a 3D hologram of Site-18
D-9265: A movie theater
D-5573: A better movie theater
Dr. Smith: An exact replica of the first two floors, including the exterior
D-3759: A room containing the pocket dimension which contains the house. Subject returned after 9 days.
D-4758: A room with the words “I’m not crazy” erratically written on the walls
Dr. King: A room filled with nothing but apple seeds
