Scp

SCP Foundation has nothing to do with Cabin in the Woods. The true Fan Base of SCP is just so amazing and supportive.

There is the SCP-173 cameo, they appear behind the "Sexy Witches" and, of course, doens't appears on the purge.

The first SCP, SCP-173 was made at 2007, and SCP-CB is based on the SCP Foundation.
