Nugs are a species of frog-like creatures in the iPenguin series. They are one of the major species, and debuted in iPenguin 3DS. They appear to be humanoid frog-like creatures with bulging eyes, long arms and legs, two toes, and long tails. They are commonly found in Aeru's Land, but have also been found in other places, such as Pengau City. They are normally very hostile towards everything, but have been shown to have be able to become civilized, as with Nudge and Nougat.
