If it's not ketchup, it's blood? DT is much more likely given that it's actually canon. Again, we don't see an extra human SOUL in PT when everyone's SOUL is leaving ASRIEL. There's still just 6 human SOULs.

Because, as Alphys said, monsters' bodies aren't physical enough to handle it - and can't absorb it all. DT isn't food, it's from human SOULS.

From looking at sans, we know for sure he's got a skull, a nasal aperture, orbits with sclera and color flash, apparently.

Yeah, how does he wink, then? How does this guy emote? Should I be equating PK powers with magic? How does he speak? I've played the Mother series. That kind of stuff wasn't on the menu.

If he's a human, why didn't his determination override Flowey's? Why was Flowey still able to mess around with time when a human was Underground? How long as he been a human and had no one notice? Moreso, why is he using magic when he could just fight us how any other human would fight a young child?

You know, pick them up, slap their face and take more than one hit from a worn dagger that's implied to be used for gardening. The battle system with sans makes no sense if he's a human. Look at how Chara deals with the protagonist at the end of Genocide. They walk up, slice, 99999, dead. That's a human fighting a human.

Again, there's no reason for him to be a human. It creates more plot holes than it solves. Toby loved Earthbound and was inspired by it = he didn't take a character and put them into his timeline.

And Papyrus was the only monster in game that didn't dust simultaneously. I think that's pretty special.

Your evidence is "he bleeds" when that's not even certain. DT is canon - sans being human isn't.
