Remember that skeleton pic of Jyx? Well, here's the followup.
Jyx has a natural bio-luminescence. In her bones. If you meet her in the daylight, you won't notice it. But if you see her in a dark room, you might spot it. In a pitch-black room, you'll definitely notice it.
The better her mood, the brighter her bones glow! They've been known to pulse rhythmically, in short periods, depending on her emotion, or.. for certain events.
Also, her bones are yellow. Nails, toes, horns, and even teeth. She brushes, but dey always yellow!

[No, her face isn't naturally that derpy.]
