Grubbis

The radioactive gas that flooded the city was meant to anger the troggs and kill the gnomes, and Thermaplugg's plan was brutally effective. One trogg, however, reacted oddly to the substance: Grubbis grew. And grew. It was a side effect that Sicco had not anticipated, but he's never been one to waste valuable (and dangerous) resources. This giant trogg now patrols the tunnels of Gnomeregan. His loyal basilisk pet, Chomper, helps Grubbis sniff out gas leaks, tasty fungi, and even tastier intruders.
