Unless you mentioned that she also ate a wagonload of oatmeal for breakfast before the rescuers arrived, or a whole bunch of the princesses' guards were eaten when she was captured, but there remains were not defecated yet, then the amount of scat was grossly exaggerated. As a person's body is over half water, more of their mass would have been pissed away than shat out in the first place (so mentioning the urine was a nice touch most writers seem to forget about). The amount of scat also seemed way too excessive as much of their bodies would have been absorbed and utilized by the dragon as is the whole point of eating food. One thing that seems a bit inexplicable though was how the four victims were essentially digested together in the same stomach, yet somehow got sorted out into individual turds. 'Delivering' the wannabe slayers back to the king was an especially nice touch. It was actually quite realistic in showing how dangerous and impossible to kill something like a huge, intelligent dragon would really be, unlike how easy they are to kill in stupid video games and most stories with villainous dragons there for heroes to slay. Well written and fun story with lots of great description.
