Parakrekk

The vicious amphibians known as the Parakrekk follow in the wake of the Protocairns, feeding off of the rubble the larger creatures leave behind. Long after the Protocairns have died, these nasty beings linger, tearing down structures with their claws and feasting on the fragments. Extremely good at finding concealment, they can be very difficult to root out once they have gotten a foothold in a place. Left unchecked, they can eventually destroy an entire city due to their ravenous appetite.
