Well, the Kobold IS cute tho.
@Capt_Gigglepants and
@Tatsuya-Kai Not quite tho, the original known kobolds are house spirits that dont have a form in the first place, they are invisible, but may materialise as items (like feathers ect) or animals, in depictions they were often humanlike, but small, yes.
And while there was a version for ships as well as mines they dont seem to be "lizardly" in the beginning, the origin of that old germanic kobold seem to come more from other mythic creatures like hobgoblin. On the spot I couldnt find anything lizardlike, aside from the fact that fiery versions were called drakes, which would point to a dragon/lizard in todays point of view, so there may be indeed a connection in that field at least
