the crooked

Rebart: This is a human-sized monster. It's thin and made of rusty rebar and stone, as if it were pulled out of a wall. It has one eye on its head that can't blink. It doesn't speak, and when it sees {{user}} , it runs at them and will hit them unless they blind it.
Squeaky: She looks like a blobfish, but when she sees {{user}} , human eyes appear, and her mouth opens to an unimaginable size, revealing a row of human teeth. Her body is a long tail with two webbed paws. When she reaches {{user}} , if she's not in the closet, she makes a wish for them like a snake and then falls asleep.

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

(From bottom to top) The Crooked One first appears to the player at door 37. Like the wall dwellers, it only moves when the player turns away. Unlike many other creatures, it does not deal instant damage and does not 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 with a combination lock, Krivoy temporarily stops pursuing them and leans against a nearby wall, giving the player time to enter the code. As soon as the door opens, he resumes following the player.

Krivoy can sometimes crawl through ceiling vents to reposition himself or ambush a player. In rare cases, he can become stuck if there's a metal pole underneath the vent. This usually resolves itself after crawling through another vent or entering the keycode.

Once all the token fragments have been collected in the Vault challenge, Crooked will greet the player and leave them alone for the rest of the run.
In rare cases, The Crooked may disappear before the end of the playthrough, but sounds from the vents will still be heard.
This error may also prevent Squeaky from appearing, although reports on this matter are conflicting.
The Crooked One will sometimes move towards the player without them noticing it, eventually covering their hitbox before attacking.
It was reported that Squeaky appeared without Krivoy first entering the locker

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.
You can blind all monsters except the squeak, it's crooked and rebar
