"What... where is Halloween Town?" That 'what' wasn't exactly him misspeaking, because he definitely was also wondering what it is, but... 'where' might be a better start.

Ginko was, in theory, trying not to stare too much, but... okay, who was he kidding, it was only in theory, and he was staring. This guy sure looked like he was made entirely of bone, but in that case he shouldn't have been able to move his face like that. Maybe his body just resembled bone, and was closer to flesh in texture, or was composed more heavily of life force, like the bodies of mushi... that might explain it. But he didn't seem to be any kind of a mushi - or at least any kind that Ginko had seen before.

"And I'd like to help you with that, if I can - but that'll mean figuring out where to start. Do you remember anything particularly notable about the well you saw?"
