Test A - March 27, 2021
Subject: Wooden Table
Procedure: Use SCP-4545-J to transmute table into SCP-4545-J-1 instance
Results: Instance appeared to be a table with a human head resembling that of a tanned brunette girl at one end, and referred to itself as "Table-etta". Instance walked about the test chamber and offered to hold things for others. When a coffee mug was placed on the instance's surface 14 minutes into the test, the instance stopped moving about but remained friendly and spoke cheerfully until suddenly returning to an inanimate form 16 minutes afterwards in a puff of smoke.
Analysis: So that's what this thing does…
Test B - March 28, 2021
Subject: Wooden Chair
Procedure: Use SCP-4545-J to transmute chair into SCP-4545-J-1 instance
Results: Instance appeared to be a tanned, brunette human girl measuring 2.01 meters in height. Instance referred to itself as "Chara". Upper legs appeared to be composed of thick cushion and two wooden spokes resembling chair legs emerged from the hips at downwards angles. Instance offered researchers a place to sit down, and when taken up on its offer 5 minutes into the test, appeared to sit in the air, bring its upper legs together, and move its wooden spokes directly parallel to its back, overall forming a chair-like pose. When Researcher B███ sat down upon the instance, neither party displayed any discomfort, and the instance did not falter in its cheerful behaviors, even offering to massage Researcher B███'s shoulders until reverting to an inanimate form 26 minutes later in a puff of smoke.
Analysis: Level of anthropomorphism varies greatly between instances
Addendum by Researcher B███: Permission to replicate this test? She had those magic fingers.
Addendum by Senior Researcher S█████: Permission denied. This isn't a pleasure cruise, idiot, it's the Secure-Contain-Protect foundation.
Test C - March 29, 2021
Subject: Couch D-127501
Procedure: Use SCP-4545-J to transmute couch D-127501 into SCP-4545-J-1 instance (This was accidental as the D-Class used to operate the device turned the beam on themself during the test for unknown reason, appearing to look into the light while SCP-4545-J was aimed at their head)
Results: Instance appeared to be a female version of D-127501, as though a transmutation by SCP-113 had taken place. Instance did not possess the cheerful demeanor seen in other instances and reacted with shock, upon being reassured that they would revert in a half hour, instance calmed down and revealed they possessed all D-127501's memories and personality. For the next 22 minutes they remained in captivity before reverting as expected, if slightly early on, and was returned to their cell.
Analysis: Effects on humans to be examined more in-depth. D-class personnel no longer allowed to use SCP-4545-J.
Test D - March 30, 2021
Subject: Water Dispenser
Procedure: Use SCP-4545-J to transmute Water Dispenser into SCP-4545-J-1 instance
Results: Instance appeared to be a pale human woman of voluptuous build measuring 1.78 meters in height with clear hair. Instance appeared to possess Heterochromia, with the left eye being red and right eye blue. Instance referred to itself as "Watterdee Spencer". Instance acted as expected of SCP-4545-J-1 instances, being cheerful and polite. Instance offered researchers present a cup of water, when taken up on the offer by Researcher B███ 2 minutes into the test, Instance proceeded to disrobe, revealing clear, dome-shaped water tanks in place of mammary glands. Instance anomalously produced a paper cup from thin air and filled it with a portion of its contained water. Water was determined not to contain any anomalous properties or contaminants beyond that of the Site's tap water supply. Instance reverted to inanimate form after 27 minutes.
Analysis: All progressed as expected, if somewhat inappropriately.
Test E - March 31, 2021
Subject: Researcher B███
Procedure: Use SCP-4545-J to transmute Researcher B███ into SCP-4545-J-1 instance (Testing further on human-to-instance conversion)
Results: Mimicking the results of Test C, Researcher B███ was converted into an instance while retaining full knowledge and personality of Researcher B███ from prior to transformation. Instance asked for some "alone time", request denied. Instance spent the rest of the transformation sitting around, seemingly bored, and occasionally attempted to play with its body. Senior Researcher S█████ prevented such activities from progressing each time. Instance reverted to human form after 30 minutes of transformation.
Analysis: No meaningful information gleaned.
