A Norwegian troll, common to the Southern California habitat, known for its ability to cause large, destructive interruptions in its pathway. The Gruneveld is a nocturnal creature that is highly susceptible to inebriation, and its call has been mistaken for both earthquakes and thunder. When cornered, the Gruneveld will secrete greasy fluids in hopes of escape.
I thought there was lightening outside, but then I realized it was the bellow of a Gruneveld.
