Arm 1.5

SCP-3589's anomalous properties manifest when one of its arms is removed. At this point, an amorphous mass of stem cells will extend from SCP-3589's stump. This growth will rapidly differentiate and grow into a new arm within 1.1 seconds. SCP-3589 claims to feel no pain during either this process or the initial removal.

SCP-3589 is capable of forcibly pulling off its own arms with very little resistance or difficulty. However, outside attempts to remove arms require approximately quadruple the tensile force otherwise predicted to dislocate a human shoulder.
