Napstablook's harmless text attack

Napstablook (/ˈnæpstəˌbluːk/),[1] known in the UnderNet as NAPSTABLOOK22, is a melancholic ghost monster and musician/DJ who lives in Waterfall, first seen and encountered in the Ruins as the game's first miniboss.



Napstablook's design is that of a simple ghost: mostly black and white, a long white body, two eyes with black sclerae (the white parts of the eyes on normal eyes), white pupils, and a mouth. A thin black line separates the eyes. After encountering Napstablook in Waterfall, they wear a pair of generic black headphones for the rest of the game.


Napstablook is a dour introvert with low self-esteem. Napstablook cries in battle, which may indicate some form of depression, anxiety or sorrow. Despite this, Napstablook is courteous to others and treats the protagonist as a guest when they visit Napstablook's home (even if attacked in the Neutral Route). They often employ self-deprecation and apologize for any inconveniences to be polite.

Main Story

Neutral Route

Napstablook blocks the protagonist's way in the Ruins and pretends to be asleep by repeatedly saying "Z" out loud.[2] If the protagonist cheers them up, Napstablook thanks the protagonist for being so kind and then leaves. If fought, Napstablook admits that they were lowering their HP to be polite before leaving.[3]

Napstablook appears in the center-bottom basement room of the Ruins' six-holed puzzle room if spared in the initial encounter.[4] After the protagonist talks to them, Napstablook realizes ghosts can fly and disappears.[5]

Napstablook does not appear again until the protagonist fights the Mad Dummy in Waterfall's Garbage Dump; Napstablook interrupts the fight by crying tears (mistaken for acid rain) on the Mad Dummy until they run away.[6] After apologizing for breaking up the "fun" the protagonist was having with the Mad Dummy, Napstablook invites the protagonist to visit their home.

Napstablook's home, seen on the left in this picture, is located to the west of Napstablook's snail farm.

Upon arrival, Napstablook invites the protagonist to listen to their music. Napstablook has three playable CDs: Spooktune, Spookwave, and Ghouliday. They also offer the protagonist a ghost sandwich to eat if the protagonist approaches and interacts with the fridge. However, the protagonist cannot eat the sandwich because it phases through them. After this, Napstablook suggests that they lie on the floor and "feel like garbage" together.[7] If the protagonist lies down for 20 seconds, the music becomes calmer and the background changes to a space scene. If the protagonist refuses to lie down, Napstablook exits the house through the right wall and does not return until the protagonist leaves.

East of Napstablook's house is Blook Acres, another location where the protagonist encounters Napstablook. Napstablook is the sole employee of Blook Acres snail farm because all of their cousins left to gain corporeal forms.[8][9] Here, the protagonist can play Thundersnail.

During Mettaton EX's battle, Napstablook is the first viewer to call and express gratitude for Mettaton's television programs, as shown by the typing quirks - missing capitalization, abundance of ellipses and the frequent use of 'oh' - and the way Mettaton says "NO, WAIT BL–" suggesting that he was referring to Napstablook as "Blooky," Napstablook's nickname.[10]

True Pacifist Route

In the epilogue, Napstablook and Mettaton are in front of their houses; Mettaton recruited Napstablook as his celebrity sound-mixer. Napstablook's SOUL was not absorbed by Asriel.[11] In the credits, Napstablook tours with Mettaton, Shyren and Burgerpants.

Genocide Route

If the protagonist has exhausted the kill counter for the Ruins before fighting Napstablook, they fade away when the protagonist enters their room. Napstablook does not intervene in the Glad Dummy fight, and they do not show up in their house.

In Battle

  • Napstablook's name sounds like "Napster bloke." Napster used to be a peer-to-peer file-sharing service that focused on sharing music files before being bought by Roxio. This term references Napstablook's computer being on a "music-sharing forum" and Napstablook's general affinity for music. "Dapper Blook" is a play on the phrase "dapper bloke," which is a British phrase referring to a sharply-dressed person (usually male). "Blook" may also derive from "spook."
    • The name could also reference the protagonist's first encounter with Napstablook. In the Ruins, Napstablook is found sleeping directly in the protagonist's path, with no way to go around. That is—Napstablook naps to block the protagonist.
    • Another possible origin of the name is the combination of the three words: "Nap", "Stab" and "Look".
  • Naming the Fallen Child "Napsta" or "Blooky" prompts the message "............ (They're powerless to stop you.)" and allows the name to be chosen.
  • Napstablook and the Dummy are the only enemies in Hard Mode that do not change in difficulty.[12]
  • They may be an allusion to "ghost producers," who are composers who sell their works to people who can claim the production as their own.
  • Similar to Sans, Napstablook speaks in all lower case, not even capitalizing names or sentence starters. There are a few exceptions, however.[13][14] As for punctuation, Napstablook frequently uses ellipses, often with more than three dots (sometimes many more), even at the beginning of some sentences. They also tend to omit most question marks and some periods, while using commas (and most periods) correctly.
  • "Killing" Napstablook makes the protagonist lose one "experience point," leaving EXP unaffected. Because of this, it does not cause a True Pacifist Route to end and is a hint early in the game that experience points are not the same as EXP.
  • Sparing Napstablook does not abort the Genocide Route. This makes them unique from every other boss, as sparing any other boss aborts the Genocide Route.
  • The artbook reveals that Napstablook was never originally planned to be in the game, and was just a placeholder character for the Encounter user interface mockups. Toby Fox's friends seemed to like the character, so he ended up making Napstablook real.
  • In the Undertale art book, Napstablook used to be referred to with male pronouns.[15] In the Fangamer version of the artbook, however, this has been changed to gender-neutral pronouns.[16]
  • In the Japanese translation, Napstablook uses "kimi" to refer to a person, which is usually used by males.[17]
  • Napstablook's face closely resembles the protagonist of the N64 game Glover.
