Photo-Negative Minnie appears to be a Photo-Negative colored Minnie Mouse suit, with no eyes and a pair of huge human-like teeth.
Photo-Negative Minnie will begin in Character Prep 1, offscreen. Then, she will appear in the room, hanging. This can help the player prepare for her to move.
If Photo-Negative Minnie appears in the office, the player needs to pull up the monitor and shut off a camera, to lure her to another room. Delaying or neglecting to do so will cause her to kill the player. The player also has the option to hide under the desk, giving the player a 50/50 chance of surviving. Photo-Negative Minnie will always disappear, reappearing in Character Prep 1 later.
