Pinhead- Fog Secondary Effect

  But Harry saw that the fog had worked a change in this demon, and it was not pretty. At the corners of his mouths and eyes, in the folds of his arms, or between his fingers—wherever, in short, the fog had touched him—it had apparently planted a seed, germinated not by producing same infernal vegetation, but by taking its cue from the spot in which it had been sown and growing a new life-form that was ordained by the place of origin. Thus, the seed lodged between the demon’s fingers had brought forth a crop of new fingers, all of which possessed their own beckoning life. And the seed beside the demon’s mouth had created new mouths, all of which gaped, many-toothed, within his cheek and his neck. All these anomalies were humbled, however, by the work a seed lodged in his left eye had done, multiplying the number of eyeballs so that from his brow to his cheek were bunches of wet, lidless eyes, their yellowish corneas dissected up, down, and sideways.
