Snowdin is a town the protagonist encounters after they leave the Ruins and travel through Snowdin Forest. Departure from the town takes the protagonist to Waterfall by foot or, by hitching a ride with the River Person, to either Waterfall or Hotland.
Despite being Underground, Snowdin is covered in a perpetual layer of ice and snow, and, because of how cold it is, it mainly homes monsters with thick fur or monsters that do not get cold.
- The town is home to the Snowdin Canine Unit, members of the Royal Guard, presumably because the town neighbors the entrance to the Underground, where humans can fall in.
- There are many locales here, such as the Snowdin Shop, Snowed Inn, the Snowdin Library, Grillby's, and Papyrus and Sans's House.
- The protagonist can witness the Ice Wolf throwing ice in the river, where it travels through Waterfall and into the CORE.
After completing the puzzles made by Papyrus and Sans in Snowdin Forest, the protagonist passes through Snowdin Town and confronts Papyrus in battle. If the protagonist is defeated, Papyrus places them in his shed. After Papyrus is defeated, the protagonist can leave Snowdin for Waterfall, the next main area in the game.
When the protagonist kills everybody in Snowdin Forest, the town of Snowdin and its buildings become completely deserted except for Monster Kid, who believes that Undyne will protect them. A note in the shop reads "Please don't hurt my family," while the innkeeper's child is replaced with a decoy. Knocking on the door in north Snowdin leads to no response, and the Ice Wolf no longer throws ice. When the protagonist confronts Papyrus, he notes the protagonist's odd behavior and their hands covered in "dusty powder." Due to this, Papyrus attempts to help the protagonist become a better person. Once Papyrus is killed, he still believes that the protagonist can change and promises that they can do a little better. After Papyrus's death, the protagonist can continue to Waterfall.
The Snowdin Shop is the first building the protagonist encounters after entering Snowdin Town, with a SAVE Point and a Dimensional Box next to it. It has a smaller building that connects it to the Snowed Inn. It is the first vendor the protagonist encounters in the game.
A female purple bunny runs the shop, and the protagonist can ask her what there is to do in Snowdin and about the history of the town. She is positive about the Underground's future. The rabbit who runs the Snowed Inn is her sister.
The Snowed Inn is a building in which the protagonist can sleep, and recover their health to between 30 and 38 HP (depending on their current HP) or their max HP (at LV 6 or higher). Even though the room price is 80G, the protagonist is refunded because they only stay for "two minutes." If the protagonist does not have 80G when they initially try to rent a room, the innkeeper allows them to stay for free on all subsequent visits. Alternatively, the innkeeper charges full price for all visits if the protagonist paid 80G for their first stay.
After the protagonist rents a room, they head upstairs and lie in bed for a few moments. Three white monsters snore a song in the adjacent room. The snore melody is the same as the track "Determination", and is called "
mus_snoresymphony" in the game files.
The Snowdin Library, misspelled as "LIBRARBY" on the sign, is a building near the middle of Snowdin. Around a table, two newspaper editors and a Loox are present. One editor discusses how they make content even though there is never much to report on while the other talks about their history with word searches. The Loox looks at the protagonist and sees which game troubles them the most. Depending on what was chosen during the Monster Kidz Word Search Puzzle, the Loox responds accordingly. A lizard is also present, commenting on their awareness of the library sign's misspelling.
Interacting with the bookshelves provides lore and jokes.
- (Red Book)
- (It’s a school report about monster funerals.)
- Monster funerals, technically speaking, are cool as heck.
- When monsters get old and kick the bucket, they turn into dust.
- At funerals, we take that dust and spread it on that person’s favorite thing.
- Then their essence will live on in that thing...
- Uhhh, am I at the page minimum yet?
- I’m kinda sick of writing this.
- (Blue Book)
- While monsters are mostly made of magic, human beings are mostly made of water.
- Humans, with their physical forms, are far stronger than us.
- But they will never know the joy of expressing themselves through magic.
- They’ll never get a bullet-pattern birthday card...

- Because they are made of magic, monsters’ bodies are attuned to their SOUL.
- If a monster doesn’t want to fight, its defenses will weaken.
- And the crueler the intentions of our enemies, the more their attacks will hurt us.
- Therefore, if a being with a powerful SOUL struck with the desire to kill...
- Um, let’s end the chapter here...
- (Light Green Book)
- "MONSTER HISTORY PART 4"
- Fearing the humans no longer, we moved out of our old city, HOME.
- We braved harsh cold, damp swampland, and searing heat...
- Until we reached what we now call our capital.
- “NEW HOME.”
- Again, our King is really bad at names...?
- (Dark Green Book)
- Love, hope, compassion...
- This is what people say monster SOULs are made of.
- But the absolute nature of “SOUL” is unknown.
- After all, humans have proven their SOULs don’t need these things to exist.
Some monsters hang out at Grillby's, including Lesser Dog, playing poker against itself, Dogamy and Dogaressa, Doggo, Greater Dog, Grillby, and a few others. Sans also frequently hangs out at Grillby's and even performs stand-up comedy at times.
Papyrus and Sans's House
If Papyrus is spared, the protagonist can enter his home and go on a date or hang out, depending on if they flirted with him during his battle. The bottom floor of the house consists of a living room and a kitchen, and the second floor features Papyrus's room on the left and Sans's room on the right. Sans's room cannot be entered normally. If the protagonist gained no EXP when Sans judges them in the Last Corridor, restarting the game multiple times grants them access to his room and in turn grants them access to his workshop in the back of the house, in which there are old pictures of him with his friends.
Ice Wolf and The North of Town
The north exit of the main part of Snowdin Town leads to a long horizontal room. On the right side of the room, the Ice Wolf throws ice into the east-flowing river; this ice eventually travels to the CORE.
On the left side of this room, a few NPCs are playing "Monsters and Humans" in front of their house while their father looks on.
If the protagonist leaves this room through the north exit, they arrive in a small room that connects to the water. After the protagonist reaches Hotland, this is the place where the River Person picks up and drops them off in Snowdin Town. This area is also where the Wrong Number Song plays if the "fun" value is within the range 2 to 39.
- The town's name is a play on the phrase "snowed in."
- Additionally, "Snowed Inn" is also a pun on the town name.
- In the Japanese translation, "Snowdin" was changed to "Snowful."
- "Snowed Inn" was changed to "Snotel", which is a pun on "snow" and "hotel."
- After booking a room at the Snowed Inn, the protagonist can still move around and interact with objects before being transitioned to their room. Talking to the innkeeper during the transition causes her to say, "What? No, you can't have a second key!"
- One of Alphys's cameras can be found in the trees south of the northern pathway.
- After killing Undyne the Undying, the sign in the town disappears.
- Along the way, some fuzzy folk decided they liked the cold and set up camp in Snowdin. - Snowdin Shopkeeper
- But... we all know deep down that freedom is coming, don't we? - Snowdin Shopkeeper
- There's so little to report that we just fill it with comics and games. - Newspaper editor #1
- I thought they were a waste of time. But look at me now... I'm the number-one word-search creator in the entire underground! - Newspaper editor #2
