Item #: SCP-4192
Object Class: Euclid
Special Containment Procedures: SCP-4192 is to be contained in a 2.3x2.3x2.3 meter containment cell with a air-tight sealed door and is to have all the CO2 removed to keep SCP-4192 in a dormant state. All personnel attempting to enter the containment of SCP-4192 is required to wear a strengthened hazmat suit to prevent the death of said personnel.
Description: SCP-4192 appears to be a regular purple shower pouf with a rubber suction cup attached to a thread extruding from SCP-4192. When SCP-4192 is deprived of CO2, SCP-4192 will remain motionless until any amount of CO2 is resupplied. If CO2 is supplied to SCP-4192, it will begin rolling around, via dragging itself with its suction cup, looking for a living breathing organism. SCP-4192 has been known to be capable of jumping up to 6.5 feet in the air, but scientists have yet to figure out how exactly SCP-4192 does this. Once SCP-4192 has found a subject, SCP-4192 will roll and jump onto the subject and attempt to suck the entirety of the subjects oxygen from their body via mouth, nose, or SCP-4192 will use a small retractable flexible needle to take the oxygen directly from their veins. This process usually takes about one (1) hour and appears to be extremely painful and subject will either pass out from lack of oxygen or from the pain which will give SCP-4192 an easier feeding. When SCP-4192 is feeding, SCP-4192 will begin to grow slightly and turn from purple to light blue. Once SCP-4192 has finished feeding, it will detach from the subject and begin rolling around looking for another subject.
Post-containment experiments:
Experiment Log 4192-1
Special Gear: None
Subject: D-82395
Subject is released into SCP-4192 containment and door is resealed. SCP-4192 comes to life and heads towards D-82395 and leaps on to his mouth. SCP-4192 begins feeding. SCP-4192 finishes feeding. More d-class sent to retrieve the body.
Experiment Log 4192-2
Special Gear: Hardened Mask
Subject: D-54678
Subject is released into SCP-4192 containment and door is resealed. SCP-4192 comes to life and heads towards D-54678 and leaps but bounces off the mask. Subject is shocked and asked what it was in a disturbed tone. No answer was provided and subject repeated the question and cursing at the researchers. SCP-4192 tries again instead aiming at the subjects left arm and attaching successfully. Subject becomes extremely agitated and attempts to remove SCP-4192, but fails. SCP-4192 uses the needle and sticks it into the subject. All of the scientists are surprised by SCP-4192s needle. SCP-4192 Begins feeding and subject is in extreme pain and soon passes out. SCP-4192 finishes feeding and more d-class retrieve the body.
Experiment Log 4192-3
Special Gear: Hardened Hazmat Suit
Subject: D-53739
Subject is released into SCP-4192 containment and door is resealed. SCP-4192 comes to life and heads towards D-53739 and leaps but bounces off the hazmat suit. SCP-4192 Attempts to go for D-53739 right arm, but fails to attach to the suit. D-53739 leaves successfully without incident.
Notes from dr. ████:
A hardened hazmat suit is one of the only things we have that SCP-4192 can’t penetrate that is wearable.
