Specimen 13 is the final non-boss specimen the player encounters in Spooky's Jump Scare Mansion. She first appears in Room 910.


Specimen 13 resembles a young woman with shaggy, grey-blue hair. Before the chase, she is seen sitting from behind on a floating crate wearing a towel around her waist. She reveals her true form during her death screen, where she morphs into a black-eyed old woman with long teeth.


Specimen 13 lurks within the flooded rooms. She quietly sits on top of a floating crate. When the player gets too close, she will dive into the water and the chase will begin.

Specimen 13 will only move when the player is standing in water. The Specimen itself isn't visible and can only be detected through the splashes she makes when moving. When the player stands on a crate, she won't move and will be unable to harm them. When the player goes back into the water, she will resume chase, although she will do so farther away than her last splash, preventing her from dealing unavoidable damage if she stopped moving too close to the player. The farther away the player gets, the faster Specimen 13 goes. Specimen 13 will not pause between attacks, leaving very little room for error. One must be wary, though, as she does not always spawn at the door in larger rooms.

Something In The Water


  • Specimen 13 behaves very similar to Kaernk from the horror game Amnesia The Dark Descent.
  • Specimen 13's CAT-DOS entry, when accessed, may randomly show her face obscured by her hair or her true face.
  • Specimen 13 can only be encountered once, along with Specimen 7.
  • Specimen 13 cannot reach the player while they are on top of one of the crates, despite the fact that she can be seen sitting on top of a crate before the chase.
  • Specimen 13, along with Specimen 7, are the only two specimens from the original game not found in Endless Mode.


Specimen 13`s towel was replaced by what appears to be a fish`s tail, and she now has a full 3D model. She is wearing nothing on her top half. She now has a diving animation for when dives into the water when the player gets close, but is still invisible when chasing the player.


The attacks deal higher damage, but now there is a pause between each hit. She also appears to move slightly slower.
