Grebans: confirmed

After a thorough investigation our operatives finally discovered a greban in a Cedar City morgue.  Unfortunately it had been dead for a few hours by the time our scientists examined it, but it revealed some important information.  Apparently our enemies have not yet been able to make grebans live for more than a few hours.  Without a bit more longevity the greban army we have feared is not a serious threat.  We will continue to keep you updated on our research into creating our own greban army and on our progress in thwarting the Parent Corporation's evil research into the same thing.
