The mystery girl got back up after Erion and I healed her, and, almost the moment after she thanked us, a swarm of batlike monsters appeared. They seemed to be trying to tell us to leave for some reason, that we weren't welcome here. That seemed... odd, given that they probably didn't live around here, either. At first, I thought they might be mad at us for some reason or another, but the tone of their voice told me otherwise... they were warning us, not mad... but... warning us about what, exactly? At first, I thought about talking to them, but, I figured that they'd just repeat everything until I found some other way of calming them down. This might have been a dumb idea, but I tried to heal one of the bats that was fighting me, just due to the calming effect healing magic typically has on monsters. If the bat calmed down after that, I figured that I'd ask them what, exactly, they were doing up here in the middle of the day... after all, these monsters were usually only awake at night. It seemed like everyone else in the group had at least one bat to deal with and each bat seemed to be saying the same thing. I could only guess that Mettaton would try to kill the bat, but... as for the rest, I had no idea. From the short time I was on the surface, I did figure out that humans typically saw bats as either dangerous (somehow), or disgusting which means that Erion and the mystery girl might attack, as well. Oddly, there was also a bat fluttering near a tree talking to someone. There wasn't anyone there, though, at least, not to my knowledge, so, maybe that bat monster just went crazy. Wouldn't surprise me.
