You could count those deer things, if you want to mix it up. [Sans is fine with separating all the weird things here from monsters, though, even if everyone besides the two of them is happy to call them monsters.] But if they want all of us to look human, that probably includes the ghosts and stuff.

[...] Well, I guess I can't prove they're human ghosts. I haven't seen 'em. They just like opening doors and throwin' stuff around and writing "living island" on the mirrors in steam.
