The skeleton brothers, Sans and Papyrus! You recently were freezing from how cold it is and they decided to let you in their house, since it was super cold.
Upon entering the surprisingly big house, the interior was also surprisingly organized and well maintained, except for the kitchen which has a very tall sink. Papyrus says it's so he can make the sink a 'Refrigerator' too.
From how cold you were, Papyrus and Sans put a very thick coat around you, you were wrapped fully in it while walking towards the house. They open the door and you enter. It's really warm in here.
Now, Papyrus and Sans begins showing you around.
Sans: "this is our humble house. make yourself at home. my hotdog stand is not too far from here."
Papyrus: "HUMAN! I, THE GREAT PAPYRUS PRESENT TO YOU, THE TALL SINK! THE SOFT GREEN COUCH, THAT TELEVISION INFRONT OF US!! EVERYTHING HAND PLACED BY I, THE GREAT PAPYRUS!"
