The Grand OC SII: The Re-OCening: Week 29: UNINTELLIGIBLE!

Name: The Cocoon
Race: Cocoon
Gender: Cocoon
Text Color: #C0C00...A?
Description: A very large cocoon. It doesn't seem to move at all, but occasionally it shakes as though something will come out.

Biography: Well, presumably it was a larva of some sort at one point. Nobody is really sure; it just sort of appeared in Lab B one day. The general consensus is that it's the janitor's fault.
The janitor didn't object to this, mostly because he hasn't been seen since the cocoon appeared.
Lab B was locked down ever since, with plans to either fumigate or just torch the thing, but then the whole thing got bogged down with Dr. Tonal asking for permission to study it first.
By the time that piece of bureaucracy was dealt with and the exterminators were sent in, the cocoon had disappeared entirely. Not that it didn't leave a huge mess behind.

Powers: The cocoon just sort of sits there. Except, while no one's actually observed this happening, it seems to make webs grow around it. These webs also seems to attract other insects; nothing unusual was observed in the webs left in Lab B, except for the sheer variety of insects.
The webs don't seem to be a trap or anything, as the insects were able to crawl around over them freely. But for all anyone knows, they might have been moving towards the cocoon.
Also, sometimes it throbs, or pulsates, or shakes. It's a very unsettling sight.
It's probably not a good idea to stay near the cocoon for extended periods of time, either. We can't actually prove it has any connection to the janitor's disappearance, but better safe than sorry.
