It's their baby, Zorby. <3
Mama's a demon so he's half. He has two sets of eyes and arms, and two mouths.
The second sets are not fully functional, his arms are floppy, he drools constantly from his second mouth and wheezes like a pug. The vision in his second eyes is very bad and he cries into them a lot which makes him even more agitated. x(
But hey, he has a cute fauxhawk!
