Papyrus and Sans's house

YOU'RE IN MY HOUSE. GOOD CHOICE!
THOUGH I GUESS IT'S TECHNICALLY SANS'S HOUSE TOO.

Papyrus when called from inside his house

Papyrus and Sans's house is a location in Snowdin Town. Christmas decorations adorn the house, and it is unlocked after the protagonist befriends Papyrus. To the left of the house is Sans's mailbox, which is full of junk mail, and Papyrus's empty mailbox.

Features

• The date/hangout with Papyrus occurs in his room.
• On the console versions, the Dog Shrine can be accessed by entering through the sink. On the Nintendo Switch version, this is the location where Mad Mew Mew can be fought. On the Xbox One/Xbox Series X|S version, both the Dog Shrine and Mad Mew Mew's encounter room are replaced with a Dog Casino.
• If the protagonist gained no EXP by the time they reach the Last Corridor, Sans's room can be unlocked, and it contains a key to his workshop.
• Papyrus's toolshed is located outside of the house, serving as a makeshift prison if the protagonist loses to Papyrus during his battle.

Main story

Neutral Route

The protagonist cannot access the house when they first enter Snowdin Town. If Papyrus is spared, he relocates to the front of his house, where he unlocks the door and lets the protagonist inside. If Papyrus is killed, the house remains locked for the remainder of the game.

If the protagonist has befriended Undyne, she relocates to the front of the house next to Papyrus. Interacting with her reveals that Papyrus and Sans live in Snowdin since the rent is cheap, and that Sans pays for their house. However, Papyrus does not know where Sans gets his income.

True Pacifist Route

After receiving Undyne's call to meet with her in Snowdin, she gives the protagonist a letter to deliver to Alphys. The protagonist can check Papyrus's mailbox while holding the letter, which causes Undyne to think they are attempting to deliver the letter to Papyrus.

First floor

The first and second floors of the house

The kitchen

The first floor of this house contains a living room and a kitchen.

The living room features a television that is always set to one of Mettaton's shows when turned on. The living room also hosts Sans's pet rock, which is covered in sprinkles, and one of Sans's dirty socks with a series of sticky notes attached to it. These sticky notes depict Papyrus nagging Sans to pick it up. The living room also contains an old couch that gives the protagonist 20 GOLD when they first check it, and a joke book that contains a quantum physics book which contains another joke book containing another quantum physics book. The protagonist decides to stop at this point.

The kitchen contains a stove with an empty pie tin in it, a trash can, a tall sink, and a fridge that has containers labeled "spaghetti" on one side and an empty bag of chips on the other.

Dog Shrine

Main article: Dog Shrine

The Dog Shrine is an area exclusive to the console versions of the game that contains a shrine for the Annoying Dog. It is accessible by entering through the sink in the kitchen.

Second floor

The second floor of the house contains a framed painting of a cartoon bone and doors leading to Papyrus's room and Sans's room. The door to Papyrus's room is plastered with labels reading (NO GIRLS ALLOWED!), (NO BOYS ALLOWED!), and (PAPYRUS ALLOWED.). The door to Sans's room has multicolored flames under it which do not hurt the protagonist if stepped on. This door greatly resembles the shortcut doors in Deltarune.

Papyrus's room

Papyrus's room. This is where the date/hangout takes place.

Papyrus's room is where the protagonist befriends Papyrus.

His room contains a racecar bed, action figures, pirate flag, a bookshelf with complex tomes about puzzle creation and children's books, a computer opened up to a social media website, a box of bones, and a closet with clothes neatly hung up inside.

Sans's room

WHY WERE YOU USING A TREADMILL IN THE DARK?
IS SANS PRANKING YOU ACROSS TIME AND SPACE?
I HATE IT WHEN HE DOES THAT!
HOW IMMATURE CAN YOU GET?

Papyrus when he finds the protagonist in Sans's room

Sans's room is unlocked in a no EXP earned Neutral Route by listening to Sans in the Last Corridor explain EXP and LOVE and then reloading the SAVE file. This can also be accomplished by having already completed the Neutral Route once and then returning to the area in a second Neutral Route. After either method, Sans notices the protagonist has already heard his spiel and exchanges one codeword, and then another, which is revealed by reloading again. Sans then gives the protagonist the key to his room, which mysteriously appears on the protagonist's keychain.

Sans's room. The self-sustaining trash tornado may rarely have the Annoying Dog.

When the protagonist first enters the room, they walk into what is seemingly an empty void. After a bit of walking, Papyrus turns on the lights to the room and tells the protagonist that they were using a treadmill in the dark.

Sans's room is messy, containing a self-sustaining tornado of trash, an unused treadmill with a note that reads "the truth is that you got owned, nerd....." It also contains a dirty sock pile, a worn mattress with sheets bundled up in a weird creasy ball, an uncovered pillow, a "thank you" letter addressed to Santa, a lamp with a flashlight that is out of batteries stuck in the bulb socket, and a drawer with a Silver Key, clothes, and trombones inside of it. Rarely, the Annoying Dog appears in the self-sustaining tornado of trash.

Papyrus's toolshed

HELLO. THAT'S NOT MY HOUSE.
THAT'S JUST MY COOL TOOLSHED.

Papyrus discussing his shed

Papyrus's toolshed, also known as the capture zone, the doghouse, the guest room, the coolshed, or Papyrus and Sans's garage, is a small shed located to the right of Papyrus and Sans's house. The protagonist wakes up here after losing to and being captured by Papyrus. The contents in the shed slightly change the first two times the protagonist loses to Papyrus.

Inside the toolshed. There are large bars and notes regarding the protagonist's capture.

The shed starts out with a bowl of dry food, a squeaky chew toy, and a bed that is too small to sleep on. There is a note that reads "SORRY, I HAVE TO LOCK YOU IN THE GUEST ROOM UNTIL UNDYNE ARRIVES. FEEL FREE TO MAKE YOURSELF AT HOME!!! REFRESHMENTS AND ACCOMMODATIONS HAVE BEEN PROVIDED. -NYEHFULLY YOURS, PAPYRUS." The bars of the shed are built too far apart, just like the ones on the bridge in Snowdin, so the protagonist can easily escape from it.

Papyrus's "cool toolshed", which has no apparent tools inside of it

The second time the protagonist loses, there is a hot dog cut up into the bowl of kibble, and the note has been changed, now reading: "PLEASE ASK BEFORE YOU ESCAPE!!! WHEN YOU WENT MISSING I GOT WORRIED SICK!!! -SLIGHTLY BONETROUSLED, PAPYRUS." The third time the protagonist loses, Papyrus's note just says: "IF YOU'RE JUST LOOKING FOR A PLACE TO STAY... JUST ASK!!! YOU DON'T NEED TO FIGHT ME!!! -YOUR HOST, PAPYRUS." The word "Bonetrousled" in the second note references the title of the track that plays while fighting Papyrus, Bonetrousle.

After three losses to Papyrus, the next time the protagonist meets him, he gives them the option of skipping the fight, saying that he is getting exhausted from capturing the protagonist. Accepting his offer leads to the same post-fight dialogue as if the protagonist had fought and spared him normally.

If the protagonist attempts to access the shed after befriending Undyne, Papyrus informs the protagonist that it is his "COOL TOOLSHED". Undyne then exclaims "Do you call it your COOLSHED!?" Papyrus admits that he has never thought of that, and adds "THAT'S WHY WE'RE FRIENDS, UNDYNE. YOU ENRICH MY LIFE WITH SHED-BASED PUNS." Undyne comments that this is the only shed-based pun that she has ever made.

If this room is accessed via messing with the SAVE data, the note reads "WHAT!? THAT'S IMPOSSIBLE."

Papyrus's Toolshed has almost the same layout as Napstablook's house. Toby Fox had intended to change this, but he never got around to it, as mentioned in the UNDERTALE Art Book.

Sans's workshop

Sans's workshop

Sans's workshop is located in the house's basement. It can be found behind the house and can only be opened with the Silver Key found in Sans's room.

At the bottom-right corner of the room, there is a strange, covered-up machine that seems to be broken. The workshop has four drawers, but the protagonist cannot interact with the rightmost two; in an attempt to do so, they interact with the blueprints on the shelf just above the drawers. The blueprints are described as being of a machine and written in unreadable symbols (which may be the Wingdings associated with W.D. Gaster, or Alphys's handwriting). The second drawer from the left contains a badge. The first drawer's contents change depending on some of the player's previous actions; it always contains a photo album with photos of a happy Sans along with many other people the protagonist does not recognize. After Asriel's battle, another photo shows up with the protagonist, Sans, and all of the protagonist's friends. Finally, only after the v1.001 patch has been applied, and after talking with the Clam Girl and learning of Suzy, a card sticking out from the back flap of the binder appears, described as a poorly drawn picture of three smiling people with the words "don't forget" written in lowercase. This could be a reference to/foreshadowing Deltarune; Don't Forget is the name of the game's main theme.

Trivia

• No music plays in Papyrus's room while in the overworld, even during the True Pacifist Route epilogue where Reunited plays in every other room.
• Although there is a visible balcony on the right side of the house, it appears it cannot be accessed.
• The garbage bag inside the trash can is named "Trashy". This name is shared with a trash can NPC in Deltarune.
• There is a bug that occurs when the protagonist looks under the sink. The Annoying Dog's tail clips through the right side of the sink when its eyes widen upon being found.
• There is a stray pixel behind the table with the action figures.
