Raleigh Sewer Monster beneath Cameron Village

It has come to my attention that an unidentified blob of pulsating goo has been discovered in the sewers of Raleigh, North Carolina, underneath Cameron Village. The YouTube video contains footage of the organism shot in April of 08', and has gone viral on the internet.

Some are speculating that it is a congregation of tubifex worms, which I personally find unlikely, especially since the mass is pulsating in unison. There is another explanation which I find more probable, however. That would be a colony of bryozoan which are known to form clusters and usually dwell in dark wet habitats.

Individually these invertabrates are very small in size and have tube-like bodies, and tentacles. Got a better explanation for the sewer monster? Let me and the rest of the world know by leaving a comment below.
