It's a chunk of crystalline rock, but it almost feels alive. Its color changes greatly depending on angle and lighting, but in neutral conditions seems to be a pale blue in hue and with a violet sheen. The only indication of life is a slight warmth.
Inexplicably, the chunk of rock has slowly morphed into the shape of a canine head. You had first noticed it sprouting little buds of crystal that now form its ears, then its tail, and then a long snout. Finally, it has developed faceted eyes, and now moves around by hopping. Despite the creature's hardness, it never seems to chip or crack when bouncing on another hard surface, although the noise is harsh to your ears. Even though its growth has slowed since it developed eyes, you can see the bottom of the crystalline animal begin to grow what you can only assume will be its legs.
