Subject 2

Subject 2 is a defective slime zombie, and as Subject 1's "pet", serves as a major antagonist in Subject 4. It is later consumed by Parker to become the Monstrosity.

Appearence
Subject 2 was the first experiment utilizing Toxadoma Mucii, and, while loyal, did not have an effective means of transmission, resulting in it being a failed experiment. Subject 2 utilizes Mushroom like spores for transmission, which can be neutralized rather easily through cool temperatures.

Subject 2 has a frog-like face with giant cheeks. It has three eyes, two large ones and one small one. Subject 2 has mushroom like growths all over its body, which can be used for transmission.

Unlike Subject 3, Subject 2 is lanky and frail. Despite this, it is rather strong, easily being able to restrain the protagonist. Subject 2 also has webbed arms and squeaks when impacting a surface.

Personality
Subject 2 does not demonstrate a clear personality, though is shown as ravenous and loyal to its master.

Gameplay
In night 2, Subject 2 is shown briefly observing the player through the pipes after causing extra Toxadoma Mucii to enter the devices.

In night 3, Subject 2 is in the vents. The player must keep the temperature at an idea level to keep the creature nearby, but not in the room. Warm temperatures will cause it to flee while cool temperatures cause it to get closer.

In night 4, the protagonist must crawl rapidly through the vent to avoid Subject 2, who is not far behind.

In night 5, Subject 2 is presented to be the main threat, until being engulfed and assimilated by "Parker", resulting in his death.

Trivia
In the conceptual phase of the game, Subject 2 was absent entirely, replaced instead by a blue creature. This was soon scrapped and Subject 2 was born.
