New Monster – Goblin (Stellar)

As challenged, a different type of goblin:

Goblin (Stellar)

Mirror, mirror polished bright
Mirror, mirror warding light
Mirror, mirror night and day
Goblin, goblin keep away
-Traditional Visse Cleaning Rhyme

Peering in at the window is a small twisted, perhaps once human face, with a shock of untidy blue hair and wild green eyes, slitted like those of a cat.  It laughs maniacally displaying yellowed needle-like teeth and is gone.  A moment later, the door swings open, though there is no one there.  You hear a footstep behind you, spinning to look, you see nothing.
