Narlihog has a two-toned fur in dark grey and white, and a bright orange-red pig-like snout and design. He's one of the good Narlies (he and Narliphant are good, the rest are evil which feels a bit racist to call a species evil but hey, Rock Lords).
All the Narlies are pretty much the same. Narli-hog at least has a nice fur colour scheme and seems to be one of the easiest ones to find. If you get lonely, perhaps you could pretend he is a hamster and pet him.
