It's interesting to see that pretty much all of the little jokes and silly NPCs that I didn't know what to make of actually all have some kind of obscure backstories. The dinosaur story is pretty fantastic, I have to say. I am a bit surprised you never talked to the clown or the rabbit in Pearlton, though. Also, I always thought the "punching trees" guy was supposed to be a Minecraft reference... Wrong microgeneration, I guess?
Is there some kind of story behind the "The Thing" enemy, by the way? I always thought it was one of the most impressive-looking battlers Enkur made, and you seem to think so too. And was its "Sexy Beam" attack just called that because of the colourful animation, or is there some in-joke behind that as well?
I don't really have much to add concerning the more serious parts of this episode (especially the bit about shooting the Lodites), since I already mentioned that in my own playthrough.
P.S.: After rereading our comments on the third video and finally having played Undertale myself, I just had to put this together. I know it's silly, but I couldn't resist.
