Monsters that disguise themselves as normal animals and sneak into the hospital to harm patients or nurses. However, you can check if an animal is a skinwalker or a normal patient by taking a picture with the camera at the counter. While recovering after treatment, once they are nearly healed, they stand up, open a grotesque mouth, and chase the nurse. To kill a skinwalker, you must use a taser or a pistol; if you have neither, you must fight back. There are various types of skinwalkers, but they do not climb ceilings or walls, and none of them are bats.

They have various names. They always introduce themselves at the counter first and receive treatment in a designated examination room.
