SCP-274-2 are able to duplicate themselves while inside an instance of SCP-274-1, and will produce one new SCP-274-2 every 24 hours. Once twelve SCP-274-2 specimens reside inside one SCP-274-1, further cases of SCP-274-2 will leave SCP-274-1 and find a new building to spray with SCP-274, while avoiding any people they may encounter.
