Gnawmbies were a special form of zombie that gnawed on Route 50 members and transformed them into zombies as well; the earliest victim of the gnawmbie virus was Navarr. After turning into a gnawmbie, one goes around gnawing on other people and turning them into gnawmbie as well. There are three known cures: DP's serum, Kat's "sexual harassment" warning lecture, and eventual virus decay. It is unknown how far the virus spread before unknown measures were taken to combat them. Today, however, the gnawmbie virus is fully contained, and there are no gnawmbies left (except for Electron on his occasional visits).
