Brian officially claims the crawlspace room as his own! I remember years later I finally drew a layout of Orneryboy and Dirtygirl’s house so that I could keep all the rooms consistent between strips. I should’ve done it WAY sooner than I did, because some areas were very difficult to retroactively architect — Brian’s crawlspace being one of them. Its only realistic feature is the placement of its door; the inside is much larger than it should be, kind of like Snoopy’s doghouse.
