Still, he can see Papyrus's point as well. They're stuck in one place, attached to the ground they grew from. It makes sense that they wouldn't know as much as others who could move around. But on the other hand, they would know that one place very well.

Cole thinks he'd rather know a little about a lot than a lot about a little.
