Skullface Superarctic is a combination of the dominant skullface mutation and the homozygous incomplete dominant superarctic mutation. Superarctic stimulates melanin and reduces other pigments, specifically the background pigment. The skullface mutation gives the reduced head pattern. Both together seem to give a translucent lavender opaque belly, which looks like the belly of a true hypo. With some, the tongue is also not black but pinkish.
