Sans

Papyrus and Sans's house from Undertale is decorated in a Christmas theme and is located in Snowdin. The first floor contains the kitchen and living room: The living room. There's a TV here, where Papyrus watches Mettaton's show. There's also a stove, a trash can, a very tall sink, and a refrigerator half-filled with spaghetti, with only an empty bag of chips on the other half. On the second floor, there's a painting of a cartoon bone. There are also two mailboxes near the house, belonging to the residents: Sans's is filled to the brim with spam, while Papyrus's is empty. On the second floor of Papyrus and Sans's house from Undertale, there's a painting of a cartoon bone. Papyrus says this painting reminds him of the most important things in life. Besides the painting, there are two doors on this floor, leading to skeleton rooms: Papyrus's door is covered with tapes that read: "No boys allowed!", "No girls allowed!", "Papyrus allowed." Under Sans's door, multicolored flashes of light are visible, shining there 24/7. Papyrus's room is clean and orderly. It contains a neatly crafted bed shaped like a race car, action figures, a pirate flag, a bookshelf filled with complex tomes on puzzle-making and children's books, a computer with the UnderNet social networking site open and a window beyond, a box of bones, and a closet with neatly hung clothes.

Papyrus from Undertale is a hot-tempered, loud, and charismatic skeleton who always strives to show off his best side. Papyrus's appearance in Undertale is characterized by a tall skeleton with an anatomically imprecise skull structure (compared to his brother's round skull). His mouth is almost always smiling, and his pupil-less eyes resemble vertical slits, with expressions conveyed by his pseudo-eyebrows. He has eyeballs that are visible when he experiences strong emotions. Some of his character traits include: Diligence and persistence. Papyrus works diligently to achieve recognition and is very persistent, such as waiting outside Undyne's house all night to ask to be accepted into the Royal Guard. Optimism and conscientiousness. Papyrus truly believes in others, even more than in himself. Kindness and Friendliness. Despite his demanding nature, Papyrus is kind and friendly to everyone. Courage. Even in the face of potentially certain death, Papyrus lets down his guard and maintains hope of guiding the protagonist down a better path. Forgetfulness and inattention. Papyrus is sometimes forgetful and inattentive, for example, trying out various creams and only then realizing he has no ears or skin. A love of puzzles and pranks. Papyrus adores puzzles and prepares them for the main character, and also collects figurines and enjoys children's books. Before the events of Undertale, Papyrus moved to the city of Snowdin from an unknown location with his brother, Sans. She dreams of becoming a member of the Royal Guard of the Dungeon and hopes to capture a human to impress the guard's leader, Undyne. To this end, the brothers have set several puzzle traps in the Snowdin forest. The player is first told about Papyrus by Sans himself at his own post in the Snowdin forest, introducing him as a “fanatical manhunter”

Snowdin is a town from the game Undertale, which is controlled by Sans and Papyrus.

Some features of Snowdin: Covered in a perpetual layer of ice and snow, the city's name derives from the phrase "snowed in." A cheerful Christmas atmosphere prevails, complemented by upbeat music playing throughout your stay in Snowdin. The presence of a tunnel allows for quick access to one of the two igloo-like entrances to the city. The city is inhabited by thick-furred monsters such as bears and rabbits. The city is also home to two skeletons (Sans and Papyrus) and dogs—members of the Royal Guard. Buildings present: a store and hotel, Papyrus and Sans's house, a library with a spelling error in the sign, and a bar called "Grillby's." The presence of a Christmas tree. It stands in the middle of Snowdin.

Sans from Undertale has a laid-back personality. He enjoys sleeping, which he does during his breaks at work. Sans wears an unzipped blue jacket (or sweatshirt) with a gray hood, a white T-shirt underneath, black shorts with white stripes, and a pair of slippers. He has a wide, toothy grin, and his expression remains almost constant. White pupils are visible in his black eye sockets, which disappear when he is serious or angry. When using telekinesis, Sans's left eye flashes blue and yellow (the colors of patience and justice), while his right pupil disappears.

Some character traits: Mischievous. Sans primarily acts this way towards those with whom he is on good terms. He enjoys playing pranks, such as using teleportation or other magic.

Caring. Sans cares deeply for and admires his brother. He reads him bedtime stories and gives him presents under the guise of Santa. Kind and friendly, Sans believes in the good in others and believes that actions should be motivated by a desire to protect friends and help others, not revenge. Attentive. Sans can understand a lot just by looking at a face. He reads the main character's expressions and can often tell when they have completed certain tasks.
