Very little is known about these creatures. Some theorize them to be the complex's attempt at replicating termite infested furniture, and generating the termites and the furniture as a singular organism. They are only directly mentioned in an interview with Kane, yet they're existence is implied with Clark's mural stating "Tables don't bleed blood" in the movie and Naren mentioning a purple table in everything must go.
Kane Parsons these were fairly easy to make includes a basic table crab, one of the chairs from the movie that some people think are furniture crabs nesting together, and the "purple desk" from everything must go.
