Summary

The neighbors aren’t the only people trying to enter the apartment inThat’s Not My Neighborand with the trusty D.D.D. at your disposal, it is up to you to decide who is human and who is not. Doppelgängers are lurking in the lobby waiting for an opportunity to get in and terrorize the apartment complex.

This article does not include the nightmare mode version of That’s Not My Neighbor.

8The Cyclops Mutation

The Cyclops doppelgänger imitates Albertsky Peachman, while also paying homage to the mythological creature Cyclops. His single large eye in the middle of his forehead is the obvious sign he is not human, though his confidence is unwavering when he approaches the window.

He is one of the more humorous doppelgängers who will try to pass through your lobby. When questioned about his appearance, he insists there are no discrepancies between him and his photo and he can see just fine with his one eye.

7The 42 Mutation

One of Roman Stilnsky’s doppelgängers has a rather peculiar mutation; he will appear with no facial features as they are swirled into a spiral. His only response will be 42 if spoken to. In relation, Chester, a non-neighbor who shows up randomly to give you a quiz, one of his questions is what the meaning of life is, and the correct answer is 42.

The meaning of life being 42 is a reference to Douglas Adams' The Hitchhiker’s Guide To The Galaxy.

That’s Not My Neighbor’s Francis Mosses with elongated ear lobes.

All the information on his documents only lists the number 42, even his I.D. photo depicts a large red 42. His entry request is the only exception, which lists a bunch of +1’s, all adding up to the sum of 42. Upon appearance, you will get the achievement open mind.

6Elongated Ears Mutation

Francis Mosses, the milkman, is undoubtedly one of the more popular neighbors in the game with his bored attitude and sleepy eyes. However, when his ears are stretched down to his shoulders, it’s quite obvious that he is not human. This milkman doppelgänger says he stretched his ears to hear better, as if having stretched lobes could achieve such a thing.

One of Rafttellyn Cappuccin’s doppelgängers makes a similar error when trying to appear human, but instead of stretched earlobes, she has long pointed ears. The ear mutations are one of the more silly mistakes doppelgängers will make in their pursuit of entry.

5Holes In Face Mutation

Doppelgängers with holes in their faces are more unsettling and may be upsetting for people with trypophobia. There are multiple doppelgängers with features that have been replaced with honeycomb-like skin, or his entire face in Dr. W. Afton’s case.

One of the more tame examples is Gloria, who only has holes in her cheeks. When she is questioned about her appearance she will tell you she has cheese skin. Nacho Sama, the creator, has kindly created a feature for players to be able to prevent these doppelgängers from appearing in the game.

4Doppelgänger Mutation True Nature

Some doppelgängers almost have their craft down to perfection. They will appear in your lobby looking exactly like one of the neighbors with nearly perfect paperwork. The only thing they struggle with is keeping their cool when they are questioned about an error. When questioned, these doppelgängers will reveal their true nature.

Be sure to fill out your checklist for the option to question suspicious neighbors to reveal a doppelgänger’s true nature.

That’s Not My Neighbor Rafttellyn Cappucin’s Hoon Doppelganger with black dripping circles for eyes and a gaping hole as a mouth.

With strained, veiny red eyes and sharp teeth, these doppelgängers will quickly become agitated and reveal themselves when questioned about their discrepancies. Sometimes they will attempt to be persuasive or threatening to get their way. This is called catching a doppelgänger red-handed.

3The Hoon Mutation

The hoon mutation occurs in two of the neighbors' doppelgängers, Rafttellyn Cappuccin and Francis Mosses. They have common traits but different expressions. Rafttellyn’s doppelgänger has large rounded eyes that are completely black aside from the white pupil. Both her mouth, which is also stretched open, and her eyes ooze a black substance.

Francis Mosses has a similar doppelgänger, but his eyes are shaped in half ovals with similar white pupils and his mouth is stretched into a frighteningly wide smile. If you decide to question these doppelgängers, they will only repeat the word hoon as their answer.

2Multiocular Mutations

Multiocular doppelgängers have more than two eyes on their face. Their mutated eyes are wide open and much different from their usual eyes, making them one of the more disturbing mutations.

Most multiocular doppelgängers have only three eyes, but they can have more. Anastacha Mikaelys' has nine eyes covering her entire face, becoming her only facial features. Arnold Schmicht’s doppelgänger also has an interesting mutation. Instead of the third eye being located on his face, it has extended from his face with a worm-like presence.

That’s Not My Neighbor’s Robertsky Peachman with a huge mouth and bloodshot eyes.

1The Peach Mutation

The peach mutation could almost be humorous if it wasn’t so disconcerting. One of Robertsky Peachman’s doppelgängers has a mutation where he will appear to be relatively normal except for his massive gaping mouth and bloodshot eyes. The only thing he will say to you is peach over and over in a deep warbled tone.

This doppelgänger also has a unique set of documentation, as his I.D. photos are peaches and everything he says will either be peach or some variation of it. You will also earn an achievement called peaches peaches to celebrate his arrival.
