Spectral Rats are a Hazard that was added in Version 1.1 of the PC variant of Granny and in Version 1.6.1 of Mobile version. They are one of the new "Pets" that were added in that update. They only appear in Nightmare Mode, so you do not have to worry about them at all on all other normal modes. They appear at random, so beware where you step. Sometimes, stepping on a rat is inevitable, as they may block a narrow way. Just be sure to know Granny's position before intentionally stepping on it.
The Spectral Rats are the fourth most dangerous character in Granny (first being Granny, second being Spider, third being Crow), as they temporarily hinder your vision, and in that process alert Granny.
Upon getting bitten by a Spectral Rat, you will receive a short stun, similar to the Jail Ventilator, but much shorter.
Hindrance Of Vision
During the stun (bite) from the Spectral Rat, the screen will shake violently, the borders will get splattered with blood, and the edges of the screen will be drastically darkened, and a lens distortion effect will be applied to the entire view.
Alerting Of Granny
During the bite of the Spectral Rat, the Spectral Rat will hiss. This hiss will result in Granny coming to the location of the hiss, and if she sees you after the hiss, she will follow you, as normal.
An unknown amount of Spectral Rats spawn in the house at the beginning of Day 1, and their exact locations at the beginning of the day is currently not known. The Spectral Rats seem to have the ability to "Teleport" between rooms, and there appears to be at least 3 or more Spectral Rats at at time in the House at once, but it is widely assumed that the Spectral Rats re/despawn at their own will. The "3 or more" statement is supported by the fact that upon leaving a room with a Spectral Rat already in it, there may be 2 Spectral Rats in the next room.
The Spectral Rats will commonly walk for a short period of time, and then they will stop and rest. During the "resting", the Spectral Rats will bob up and down, but nothing much else will occur. The "resting" can also take place on Staircases and in Hallways, which will block the path from the Staircase or Hallway. This will result in time being wasted and your frustration, as a Spectral Rat that is on a Staircase will block the path, and it is only very rare to walk past one and not get bitten (check out the end of this paragraph). You would have to risk a bite in that situation, which would alert Granny. The Spectral Rats will completely ignore the Player’s presence and will not chase them, but if they wander into the Player or the Player steps on them, they will bite and begin running away. In some very rare instances (most commonly in the Staircases and Hallways), you can get extremely close to a Spectral Rat, but it won't bite. It is still unknown why this occurs, but is assumed to just be a simple glitch.
The Spectral Rats are able to wander through closed doors, and in some cases they even appear to have the ability to teleport between multiple rooms.
The Spectral Rats CANNOT be stunned or killed by any weapon such as the Crossbow, the Shotgun, the Pepper Spray, the Sauna, the Car and the Freeze Trap. This rule also applies to the the Unstable Flooring and Granny herself, as those things that knockout and or kill you cannot influence the Spectral Rats either. The Bear Traps (and the flesh variants) also apply, as Spectral Rats cannot interact with them.
The Spectral Rats cannot access the Secret Tunnel, the Hidden Tunnel, the Attic Tunnel. Those are total safe zones. Most of these examples are due to the size of the Structure, but logically, the Spectral Rats should be able to access those areas. They will mainly wander around the Ground Floor area, while sometimes going through the Upper Floor and Attic. They will never go into the Secret Area Bottom Floor. They can also teleport.
- Once you get bitten by a Spectral Rat, the screen will fill with small droplets of blood on the edges, similar to the effects that occur after touching the running Jail Ventilator, during Day 4 and 5 (or Day 6 if the painting is complete), after being caught by Granny, after being bitten by the Spider, after falling through the Unstable Flooring, and after being caught in a Bear Trap.
- For some strange and unknown reasons, the Spectral Rats cannot access the "Tunnel" Structures, but they really should be able to physically, as they are small creatures.
- These Spectral Rats appear to be ghosts (that is why they are dubbed "Spectral Rats", spectral meaning "of or like a ghost"), and their strange origins are still somewhat unknown.
- These Spectral Rats were a strange addition to Granny, as they have no relation to anything in Granny previously, and they were a random choice for a new character (antagonist).
- Unlike the Spider and Crow, the Player can't kill these Spectral Rats.
- The Spectral Rat model is sourced from Wild Life - Random Beasts, a Unity Asset Store package available for purchase. The same can be said for the new 1.6 Spider model.
- The Spectral Rats used to be an exclusive thing to the PC version, but as of version 1.6.1, they also appear in the Mobile version.
- If the Player shoots one of the rats with the Crossbow, it will make the same sound as when it bites the Player.￼ It will also run away.
- Sometimes if the player gets bitten by a Spectral Rat, the biting sound will be echoed.
- Sometimes, one of the rats will get stuck on the walls.
- From version 1.6 to Version 1.7.2, the Player could get rid of the blood on the screen by getting bitten by the Spectral Rats since Day 4.
- The Spectral Rats are the only pets that are free to roam the house.
