Huff... puff...!
YEAH!!! That's MY HOUSE!!!

Undyne, upon calling Papyrus immediately after befriending her.

Undyne's House is the home of Undyne that appears in the Waterfall area. It is a key location in the True Pacifist Route.

Features[]

  • The hangout with Undyne occurs here if the protagonist gained no EXP. After the hangout, the house is no longer accessible.
  • If Undyne is befriended after completing the Neutral Route and backtracking (or after resetting and defeating Mettaton), Undyne's Letter can be obtained here instead of in Snowdin.

Main Story[]

Undyne's house does not yield anything of importance until Papyrus calls the protagonist in front of the "WELCOME TO HOTLAND!" sign while being pursued by Undyne to say that he, Undyne, and the protagonist should all hang out sometime and then says to meet at her house later. Returning to this location after the call causes Papyrus to show up in front of her house.

Befriending Undyne can be completed on the Neutral Route, but it is an integral part of the True Pacifist Route. The requirements for this event is that the protagonist must not kill anyone before starting this event or else Undyne refuses to open the door and become friends with a murderer. The protagonist must also give Undyne water when she passes out in Hotland, or else she gets heat stroke and is unable to open the door.

Befriending Undyne[]

Once the protagonist approaches and initiates the hangout, Papyrus knocks on the door. Undyne answers the door asking if Papyrus is prepared for his special private training, and he then moves, saying that he has brought a friend. Undyne has an angry look on her face but reluctantly invites the protagonist inside.

Papyrus then jumps out Undyne's window claiming that he has to go to the bathroom. After Papyrus briefly returns to pose friendship as a challenge to Undyne, she insists on becoming best friends with the protagonist. When the protagonist sits down at her table, she asks what they would like to drink. Undyne however throws a spear at the protagonist once they move and says that they should point to what they would like.

During the hangout with Undyne, she asks the protagonist to choose a drink:

  • Pointing the spear at Undyne while she demands them to choose a drink causes her to ask if the protagonist is flirting with her. Selecting her again only results in repeated question marks.
  • Selecting the Sword when she demands them to choose a drink causes her to comment that she would gladly fill the protagonist with swords if they were not her house guest.
  • Selecting the Fridge with the spear when she demands them to choose a drink causes her to comment that she would never give the protagonist her entire fridge.
  • Selecting the Hot Chocolate when she demands them to choose a drink results in her telling the protagonist that the Hot Chocolate box is empty; she stopped getting it because Asgore kept getting marshmallows stuck in his beard.
  • Selecting the Soda when she demands them to get a drink results in her about to get it for the protagonist, but then realizes that they do not look like they want it. She goes on to say how soda "rots your fighting spirit," then as if the protagonist asks her, she says: "Why do I have it?" and then makes an expression similar to (:3).
  • Selecting the sugar when she demands them to get a drink causes Undyne to tell them that the sugar is for the tea, and that she is not going to give them a cup of sugar. She then asks if she looks like the ice-cream woman, following up by asking if human ice-cream women "terrorize humanity with energy spears" and if their ice-cream songs are a "prelude to destruction." The player is then given a yes/no prompt: if the player chooses "no," she replies with "That's what I thought." Choosing "yes" causes her to reply with "... what? REALLY? That rules!!!"
  • The tea, jokingly referred to as the "blatantly correct choice," is the only option that Undyne accepts as a drink.

Upon choosing the tea box (other answers only lead to another choice), she then makes tea, then sits down at the table. She then talks about Asgore and Papyrus, and explains how she came to lead the Royal Guard.

Undyne goes on to remark about how Papyrus missed his cooking lesson and demands that the protagonist takes it in his place. The attempt to make spaghetti, however, goes horribly wrong, causing the house to burst into flames. Undyne challenges the protagonist to a "final rematch" to regain her lost pride. After she realizes that the protagonist does not want to harm her, she stops fighting.

Concluding the hangout, Undyne runs off to see Papyrus as her home is now on fire. She can afterward be seen in front of Papyrus and Sans's House. It the protagonist speaks with her there, she gives the protagonist Undyne's Letter if their inventory is not full and says to deliver it to Alphys.

True Pacifist Route[]

If the protagonist did not befriend Undyne before defeating Asgore and backtracks to befriend her, she gives Undyne's Letter immediately after the event. Undyne mentions that Papyrus proposed the idea of giving the letter to the protagonist, but he told her about it when she still hated them. If the protagonist's inventory is full when Undyne attempts to give them the letter, the letter must be obtained from Papyrus and Sans's house.

Geography[]

Undyne's House location interior

Undyne's house appears to be a massive angry fish with the door resembling the mouth and the windows resembling the eyes. After completing the events that occur in this area, the house turns entirely black, and fire can be seen from the house's windows and slightly open door. The "eyes" also change from angry to teary. Mad Dummy appears here after their battle, unless killed during the Genocide Route.

The interior of the house consists of a kitchen with a table, a chair, a fridge that keeps food warm, a sword, a piano, and a window on the left side of the house. The only other door in this room that is not the entrance is the locked door that leads to Undyne's room.

Trivia[]

Concept Art for Undyne's House

  • Opening the drawer in which Undyne stores Papyrus's present bones before sitting down to progress reveals the Annoying Dog in the drawer, which winks at the screen before the protagonist closes the drawer.
  • When Papyrus stands in front of Undyne's house before the protagonist befriends her, She's Playing Piano begins playing.
  • The Mad Dummy appears outside Undyne's house after it is fought.
    • In the epilogue of the True Pacifist Route on the Nintendo Switch version of Undertale, if Mad Mew Mew has been fought they appear instead of Mad Dummy.
  • Undyne is neighbors with Napstablook. When called outside of their house, she asks the protagonist to be kind to them.
  • Knocking on the door of the house at certain points in the game can result in varied dialogue:
    • Knocking on the door after fighting Undyne but not giving her water: "You hear irritated groans from the inside."
    • Knocking on the door after fighting Undyne and giving her water but before hanging out with Papyrus: "It doesn't seem like anyone is home."
    • Knocking on the door after killing Undyne: "It doesn't seem like anyone is home. And you get the feeling no one will be."
    • Knocking on the door while the house is burning after befriending Undyne: "Sounds like only fire lives here now."
    • Knocking on the door if Papyrus is in front of it: "If someone's there, they aren't answering the door."
      • If all conditions to start the hangout are met, the door cannot be knocked.
  • Attempting to leave the area after Papyrus knocks on the door and walks in causes Papyrus to explain that the protagonist "CAN'T ESCAPE FRIENDSHIP!!"
  • Papyrus's small animation where he dances or walks in place before he enters Undyne's house is supposed to represent him wiping his feet on the mat in front of the house.[1]
  • Calling Papyrus in this area immediately after the hangout with Undyne results in special dialogue.[2]
  • Backtracking to this area during Undyne's fight results in special dialogue.[3]
