The Snerp Herder is a hunter-gatherer who places strange creatures, Snerps, that act as booby traps that cripple enemy movement. Prone to excessive celebration, the Snerp Herders are often spurred into an absurd state of snerp herder fervor.
The Engineers would often enter the wilds in search of supplies to use for their inventions. In doing so, they would occasionally wander into the volatile, sporelike creatures that they called Snerps. Seeing an opportunity to defend their workstations from wildlife, some of the Engineers were repurposed to detect and collect these creatures, then deploy them as traps.
