Unknown Specimen 3 (A.K.A. Spooper) is one of the specimens encountered in Endless Mode.
Appearance
Unknown Specimen 3 resembles a child wearing a ghost costume and black sneakers. The sheet is white and featureless with two eyeholes. It will become tattered and soaked with blood the more it is struck with the Axe and in its bloodiest state an eye can be seen inside its chest cavity.
Gameplay
Introduction
Unknown Specimen 3 will first be found standing in front of the exit door of any given room where it might spawn. It turns to face the player extremely slowly. The door cannot be entered when it is blocking it, forcing the player to use the axe on Unknown Specimen 3.
Upon entering another room, Unknown Specimen 3 will appear again blocking the exit, bloodied from the previous encounter. The player must continue to strike it with the axe and move to the next room, Unknown Specimen 3 becoming more injured each time. After "killing" it in its sixth and most injured state, entering the next room will begin its chase.
Chase
The textures of the walls, floors and ceiling will take a more "realistic", grimy look. As the chase progresses through these grimy rooms, the player will be inflicted with different effects.
After 5 grimy rooms, there's a 50% chance that the normal or bloody version Unknown Specimen 3 will occasionally flash in the room or a hallucination, which resembles a floating, pink fleshy ball with two arms and a single eye in the center of its body; these hallucinations are harmless and will disappear when close/come in contact with the player.
After 7 grimy rooms, the player starts taking passive damage (1.6 damage per second).
Lastly, after going through 9 grimy rooms, there's a 20% chance that the player will come to a full stop and puke blood between 1 to 4 seconds after entering a room. This action inhibits movement and depletes 10 health.
Death
When it kills the player, text appears as follows:
"Beyond that door is another world.
A world made of dreams...
A world where all your fantasies have come true.
A world full of everyone's sick fantasies.
A world lusting to include you."

Trivia
- Because the doors aren't disabled when Unknown Specimen 3 appears, in some rooms it's possible to go around it and enter the next room. Thus, Unknown Specimen 3 will appear in the state it was in during the last room and continue to do so until it's hit or the player enters a save room.
- There is a glitch where Unknown Specimen 3 can be bypassed by spamming the interact key while trying to run through the door, which will eventually let the player through despite Unknown Specimen 3 being in front of it.
- Sometimes, when the player vomits, there is a chance that a fetus-like creature covered in blood will appear.
- According to the developers, upon hitting Unknown Specimen 3 for the final time, the rooms get filled with spores. These spores then form a fetus within The Protagonist's stomach, impregnating them.
- It could also be a reference to an infamous scene in Silent Hill 3, in which the protagonist vomits up a monster that takes the form of a fetus.
- Unknown Specimen 3, along with Specimen 5, Unknown Specimen 1, and Monster 5 are the only specimens that can change the textures of the walls in normal rooms.
- Unknown Specimen 3 is the only unknown specimen to appear in the Doll House.
- Akuma Kira has confirmed that the "parasite" is not Unknown Specimen 3's true form, but rather a hallucination from being exposed to the toxic rooms for too long. [1]

Gameplay
Introduction
Unknown Specimen 3's introduction room is a regular room, specifically the room with 4 different doors, one at each end of a short hallway.
Unknown Specimen 3's normal state will now teleport to the door the player is closest to, preventing them from bypassing it in rooms with multiple doors.
Chase
Its chase music will now start as soon as Unknown Specimen 3 first blocks the door instead of only after being "killed." The player will immediately start taking passive damage after "killing" Unknown Specimen 3. The hallucinations can occur at any moment in the grimy rooms; the pink monster has a lower chance to appear and it is smaller; Unknown Specimen 3's bloodied state will occasionally flash in the room, slowly turning towards the player before disappearing. The chance to vomit happens only after 9 grimy rooms.
Unknown Specimen 3's damage output has been significantly reduced, now dealing 0.2 damage per second, but it now disables healing. Additionally, the player will be slowed down while vomiting instead of completely stopping in place. The player will not vomit if there is another enemy around. Vomiting can be cancelled by going through a door at the same time as it is occurring which allows the player to negate damage.
It's good practice to look back at the entrance door while backing away from it during this specimen's chases as the player could get a surprise attack from either Monster 4 or Specimen 6.
Trivia
- There was a glitch where if the player went through a door while vomiting, there was a rare chance they would be unable to move when they entered the next room, soft-locking them and forcing them to die or reset.

During the facility's Self-Destruct Sequence, Unknown Specimen 3 will block the entrance to the tram. As in Endless Mode, the player simply needs to strike it with the axe to make it disappear. Unknown Specimen 3 will no longer appear after entering the tram. |
