Triplet
From CMPLWiki
Some Drygers have this mutation, causing the chest and torso to be sectioned in thirds instead of the usual halves. In effect, the chest and torso reflect that of a Breeder WolfSkunk. This affects all genders of Drygers. Male and Herm Dryger genitalia are not affected -- they only have one penis unless affected by the Hentai mutation.
