the crooked

All monsters can be blinded except for the Squeaky, which is crooked and rebar can be blinded by the Flash Beacon.

There are 50 rooms in total, we start at 050 and end at 000 when those creatures appear: Crooked from room 048, Squeaky from room 045 and Rebart from room 040

Rebarb appears as chunks of concrete held together by a bundle of rebar. On one arm are copper pipes, curved to resemble a hand. On the other arm is another huge chunk of concrete with pieces of rebar protruding, giving it the appearance of a mace. On Rebarb's head is another huge chunk of concrete with a stain and one eye.

Rebarb was first discovered on April 11, 2018, when the Danger and Ethical Problems Unit responded to numerous inquiries from the Moldovan Police Inspectorate and found him in an unfinished apartment building amid a "sea of ​​crushed bodies." The sole survivor was questioned by Urbanshade staff but died shortly afterward. A theory was published regarding a cover-up of information regarding a lack of safety precautions at the workplace and structural flaws in the building.

Mechanics
Rebarb quickly lunges at the player from the darkness of any room. While it's charging, the player must quickly flash the beacon to stun and repel it. If it doesn't, Rebarb will lunge at the player, dealing 20 damage, after which the player can flash it.

hostile but possible to calm down

This creature, named Squeak, has the appearance of a grotesque, elongated face. Its small, dimly glowing eyes are hidden in darkness, and its gigantic mouth expands into a massive maw with human-like teeth and a tongue. The mouth is shaped like a sarcastic butterflyfish with an open frill, making the mouth appear larger than it actually is. Squeak is the smallest known variant of the piscivorous fish. Squeak can see and is not partially blind, unlike its "brothers and sisters." Like all Eel variants, Squeak always faces its observer.

Mechanics
Squeaky works similarly to Pandemonium, automatically targeting the player and moving toward them as soon as it spots them. When the player enters a locker, Squeaky taps the locker once, remains there for a second, and then runs away. However, unlike Pandemonium, Squeaky doesn't trigger a minigame; instead, he slams into the locker and disappears.

Squeaky doesn't cause lights to flicker because it doesn't have a signal that overloads electrical circuits. And since Squeaky is smaller than all the Ugrelov variants, it's stealthier than Pinky because, unlike her, it makes almost no sound unless provoked. The only sign of Squeaky's approach is Crooked entering a locker or a faint rumbling sound, but this requires excellent hearing. The red frame will also become translucent, but this will only be noticeable 3-5 seconds before it appears in the room you're in.
It can't speak, it can only make scary sounds - hostile

kind, he is kind to the player, but today he showed it.
Honey: Even if he looks like a monster, he's kind inside.

Crooked is a tall, stocky, skeletal humanoid with a severely deformed and twisted head. He has sharp teeth, misaligned eyes, and a metal nail piercing his larger, lighter eye. A syringe protrudes from his right eye. He wears a beret with the Urbanshade logo, as well as a camouflage uniform, gray boots, and a faded blue Urbanshade jacket.

One of the eyes in Krivoy's head actively tracks the player's movements, while the larger, damaged eye remains motionless, indicating partial blindness. Attached to the back of his head is a black, parasitic organism resembling an arachnid or scorpion.

According to the dying message shown after he was killed by Krivoy, he is the reanimated corpse of an unnamed guardsman. The exact cause of death before his reanimation is unknown.

Mechanics
At door 38 (or door 2, counting from the bottom up), the Crooked One first approaches the player through door 37. Like the wall dwellers, it only moves when the player looks away. Unlike many other creatures, it doesn't deal instant damage or retreat when looked at.

If Krivoy gets too close undetected, he'll strike the player, dealing damage, and then immediately extend his hand to help them up. Notably, he won't attack if the player is looking him directly in the face, even if the player is walking directly toward him.

When Squeaky is about to appear, Crooked quickly runs to a locker and hides. This is usually the only sign of Squeaky's approach, aside from "Dead Man Mode." In "Dead Man Mode," blue visual stripes appear, indicating the locker he's hiding in. Squeaky also creates a red halo around the screen, like Pandemonium.

When the player approaches a door locked with a combination lock, Krivoy will stand next to the door leaning against the wall with his legs crossed and his arms crossed over his chest. At this moment, he will not attack because he understands that it is not fair.
