The tone of the containment procedures seems good in a ridiculous way. No complaints there.
Too much [REDACTED] and [DATA EXPUNGED] in SCP-XXXX-B's report. While I understand that you want to keep the identity of whatever freakish thing was inside the bear a mystery and what it did to the researcher a mystery, it's just very hard to understand what's happening. One idea is that you can replace the creature inside SCP-XXXX-B with SCP-████, still keeping it deliberately vague while also adding some coherency.
Example.
SCP-XXXX-B: Discovered by a team of researchers in the cafeteria of Site 24 on ██/██/████. Subject looked nearly identical to SCP-XXXX, but moved slowly and irregularly, with jerky motions. The team reported that it appeared as if something was moving inside of SCP-XXXX-B. Subject made no attempt to interact at first, until a burst in its seams revealed what appeared to be the hand and arm of SCP-████ poking out and grasping at the air. At this point, one female researcher screamed, and SCP-XXXX-B reacted by emitting a high pitched cry similar to that of SCP-████. The subject then attempted to [DATA EXPUNGED]. In the ensuing chaos, the security team was forced to terminate both the researcher and SCP-XXXX-B. Therapy sessions with the surviving members of the research team have made little progress. Approximately 3 hours after this incident, Dr. ██████ was found unconscious and bleeding in [REDACTED]. [DATA EXPUNGED] had been performed on her while she was sleeping, and SCP-████ was never found. It is hypothesized that SCP-XXXX used [DATA EXPUNGED] to create SCP-XXXX-B. Information regarding the possible origin of SCP-XXXX-B is not to be leaked to the research team members currently undergoing therapy for the incident with SCP-XXXX-B, as Dr. Carver believes it would be extremely detrimental to their recovery.
If I misunderstood your intent, then don't take this suggestion seriously, but try to at least make it a bit easier to read through all the censored information.
