They inject a sleep substance into their victims and charge them to the hideout.

They uses their victims to feed the Queen, The fate of the victims is brutal, the only thing we know is that the queen eats her prey alive.

The Queen.

The Queen is a unique entity that resides in their own floor/level (Flutter Hideout) is protected by several acolytes so it's highly recommended to leave the floor as soon as possible.

Sometimes acolytes swarms don't kill their victims, instead of inject their poison

victims a severe pain and expulsion of blood from all orifices, the victims dry out alive and then dies.

Twisted Flutter have 2 forms

The acolytes: When a Flutter got infected it becomes a swarm of 5 acolytes that serve the Queen Flutter.

The acolytes are really dangerous, they uses their fangs to inject a lethal poison that causes to the

The Talo's forgotten son
We don't have enough information about these creatures but it seem that they have much in common with the Ichor infection than we would expect.

In anomalous floors covered with water either partially or completely full of it

The aquatic form, unlike its counterpart, is a completely lethal threat, swimming really fast and under the control of an elder TFS.
The TFS can use its two large arms to dismember its victim.
The good new is that this entity can be only found

Twisted Finn has two forms, the land form that can be found on any floor, controled by a Talo's forgotten son
It can be dangerous due to the pathogen that the TFS have.
But it's not a serious hazard

The Vee (Malware Form)

It appears to have been originally created by Patient Zero, but was hacked by The Vee and the malware code stolen.

The original intentions are unclear, but the current one is used as a remote locator.

Once the device is infected it will function as a GPS for the entity.

We are not very clear about the intentions of Vee or her conscious variant.

But it seems that one of them is corrupt, but both of them oppose the mandate of [REDACTED]

It's a hive mind type, it uses its malware variant that it stole from Vee (patient 0).

If you are a researcher and you enter the facilities, try to use a private network and not connect to the building network.

The malware only needs the victim to connect to infect them.

The Vee

It is the union of all "vee" that were not yet infected, united under a single purpose [...]

It is estimated that there are 25 Vees.

Twisted Vee (or the patient 0)

The first to be infected with the ichor infection, it all started by biting [...] and drinking the contaminated ichor.

If everything was ruined, Now everything is worse

(There's only one)

"Following the source of the sound I found a trapdoor leading to a basement..."

"There she was, crying for help, Hanging from the ceiling without legs or arms"

"I heard footsteps approaching, so I had to hurry and hide."

"Something was approaching"

"I saw him, I saw Dandy "

From Jimmy's report:

"I didn't fall to the ground, suddenly I was in what looked like a train station, when I entered I realized that I was in a lobby."

"I decided to take a staff only door"

"I was in a room that looked out onto a shop, but I heard someone

"She was always self-centered, she wanted the show to be all about her and her stupid dinosaurs facts.

Since no one was paying attention to her, she decided to ruin everything.

I decided to punish her for that."

Shelly (The first)

From Dandy's interview:

"About the mains? [...]

Well Shelly, she was the first yeah...

Everything fucked up [...]

It's all her fault.

That's why I hate her.

That's why I had her locked in my basement.(+)

Twisted Shelly is a deadly threat, with relentless sight and extreme speed it locates her preys and pursues them.

Once she reaches them, she uses his blades to tear them apart.

If the victim is strong, she use her tail to weaken it.
