Class Notes reads: "Like a class 3, a class 6 is recognizable in form and behavior -- but that form and those behaviors are exclusively animal in nature. With appetites and instincts to match their living counterparts, class 6 entities can make for some of the most dangerous regularly appearing manifestations. Especially as they are not necessarily restricted to a particular size and sometimes they figure that out."
