A couple of nights ago Miss. P alerted us in the middle of the night that something had gotten through. We were confused, of course, because there shouldn't have been any Hollowghasts left. We rushed outside, only to see that exact thing standing outside in the garden. We didn't know, and we still don't know, how it got in. It almost took Jake before Ms. P could kill it. So far that's the only hollowghast I've seen, but because I've seen it at all, Miss. P is contacting her teacher to see if we missed any hollowghasts.
