Stalker (Animal Hospital)

Secret Agent: This is a black cat with yellow eyeballs in an elegant vest at work in a hospital. His job is to patrol the corridors and kill anomalies, but he is cheerful and rarely humorous (he loves new ties) and he always comes on shift at 01:00.
Dr. Harlow: This is the main doctor, a deer with a flashlight on his head for the doctors in the hospital, and he is simply the most important one in the hospital; he can fire or give a bonus for good work (Dr. Harlow has a sense of humor and can laugh at stupid situations)
Secretary: Blue bunny with black glasses and a white shirt with a black tie
The secretary records all patients and
works with documents
Psychologist: a green rabbit with a mustache and black glasses, he helps with psyche, he is very kind and cheerful

He hardly talks to anyone, he talks very rarely, but that's not it.

He likes to spy without taking his eyes off his victim, but he is not talkative and hardly speaks at all, and if you look at him, he will immediately go into a corner and merge with the shadows.

He's not very talkative to be scary.

He can rarely kill

He hides so that he won't be noticed and he can continue to scare.
He doesn't like to go outside the wall himself; he likes to be looked at and then immediately disappear so that everyone goes crazy.
