[Sans makes note of Peter's description as he stuffs himself into these clothes (which he guesses are his, since they fit, but that's very weird). He looks in the mirror at his hair and, yeah, still has no idea what to do with it. He just leaves it as the curly mop it seems like it wants to be.]

A real one? Nah. Just kids online messin' with people and then saying it was an experiment once they got caught. [Sans knows the Undernet is monster-specific, but that kind of experience has to be universal, right?] This just seems like the kinda thing a mad social experiment scientist would do, y'know? Forcing people into families and swapping 'em 'round.
