Ruminoco

Ruminoco roams up and down the Tunnel and keeps a constant lookout.  Wherever there are good guys, there are nearly always bad guys lurking around somewhere.  Bad bugs who want to mess up all the hard work, steal stuff, or generally cause trouble.  Ruminoco does his job so well that most of the time no one knows that the bad bugs are even there. He also looks after all the other poobugs, keeping everyone calm, sorting out arguments and generally making sure that the Tunnel is a happy place to work.
