This is in Oracle of Seasons. I was randomly walking around Horon with my shovel, looking for hearts...and as I dug a tile above the clock building, I found one of those holes, that have the steps and all. When I went in it, it was a big room, completely empty, with brown tiled floor. It had the normal "in a house" music and yellow brick walls, with the stairs in the bottom right corner. I've looked around the wiki but I haven't found any info about this. So what's up with this room? Is part of the plot? Is it a glitch, or what?
