Vitreolum just thought you should know about that troll in your basement. . . Okay, let's start with the most obvious example of NPU (Nice Parts Usage): the Plant Monster headpiece. Vitreolum is truly a master at NPU, and this build is no exception from that point. The use of the strange new element LEGO has produced is truly magnificent! It gives little bits of texture to the forehead of this unique creature, almost as if it has some wrinkles from old age. Other examples of NPU are the minifigure hair piece used as some shaggy chin hair, and the LEGO Chima metallic paw piece as a shoulder guard (I personally have some of those pieces and can never figure out what to do with them). All in all, the armor this creature wears is entirely made up of NPU! I could definitely see this guy in a fairy tale. . .
