Greengunk

Is there a green banker light floating around the room? That is none other than Greengunk. Greengunk might look like just a lamp, but it has no lightbulb within, and glows on its own. However, its green hood tends to ooze off droplets.

As the sight is reminiscent of snot oozing out of a nostril, many were quick to dub the creature, Greengunk. There actually are blue and white variations of this creature, known as Bluegunk and Whitegunk, respectively. As for the ooze these creatures make, fear not as it is harmless to both you and everything in your room, even if it drips on it. At most, you'll see a splash, then it vanishes. It's more visually stunning than disgusting.
