Blook Acres

Blook Acres (/bluːk/) is the area found north of the "Quiet Area" SAVE Point intersection in Waterfall. This area contains Undyne's house, Napstablook's house, Mettaton's house, and the snail farm where the protagonist can play a game of Thundersnail.

Features

• Blook Acres is separated by three paths:
  • The left path leads to Undyne's house.
  • The middle path leads to Napstablook and Mettaton's houses.
  • The right path leads to the Blook Family snail farm.

Main story

Neutral Route

After interrupting the encounter against Mad Dummy, Napstablook leads the protagonist to the "Quiet Area", and from there, they invite them to their house. Napstablook is also present in their snail farm, where they invite the protagonist to play a game of Thundersnail for the price of 10G per game. Some snail NPCs are also present in the snail farm.

Genocide Route

On the Genocide Route, Napstablook and the snails are absent Blook Acres, thus Thundersnail cannot be played. The three CDs in Napstablook's house are also not available.

Undyne's house

Main article: Undyne's house

The home of Undyne, which can be entered if the protagonist has no EXP and had her offered a glass of water in Hotland. The exterior of the house resembles Undyne as an angered fish, with two fishbone mats. Outside is the Mad Dummy, and if spared, Papyrus after fighting Undyne. Talking to Papyrus triggers the date with Undyne. After cooking with Undyne, the house catches on fire permanently and becomes inaccessible. Undyne then relocates to live at Papyrus and Sans's house in Snowdin, where she joins Papyrus in his Cell Phone calls to the protagonist for the remainder of Undertale.

Napstablook's house

Inside Napstablook's house.

The home of Napstablook, accessible to the protagonist after Mad Dummy's battle. Inside, along with Napstablook, is a fridge, a television, a spiderweb with a flyer for a Spider Bake Sale, a computer open to a music-sharing forum, and three CDs, labeled "Ghouliday", "Spookwave", and "Spooktune". These songs continue to play after the protagonist leaves Napstablook's house. If the protagonist walks in the quiet area while one of these songs plays, a unique encounter with Aaron and Woshua triggers.

Mettaton's house

Inside Mettaton's house.

The house next to Napstablook's house, which is unlocked using the Mystery Key. This key can be bought from Bratty and Catty for 600G. Inside is an entirely pink interior, with pink and star accessories. There is a pillow on top of a bed, a carpet, a poster, a single window, and a television, which are all inaccessible to the protagonist. There are six diaries on the floor, which detail the story of Napstablook's neighbor, a ghost who wanted to perform and become corporeal. This SOUL was then put into the robot body created by Alphys, which became Mettaton.

Snail farm

Napstablook's snail farm.

The Blook family business is run by Napstablook. According to them, the place used to have a large amount of business, until their primary customer (assumed to be Toriel) stopped coming. Currently, their only customer is "some hairy guy that shows up once a month"; this customer is assumed to be Asgore, who keeps canned snails in his fridge. The first pen has four snails that the protagonist can interact with, while the second pen, where the protagonist can play a game of Thundersnail, has three racing snails.
