Baby Ghost - Tumblr Posts
I said a while back that Ghostie's species, while called ghosts, aren't actually ghosts, at least in the spectral sense. Well, how's about I share a little picture to explain?

Here's a picture of Ghostie as he was hatching! Yep, ghosts in his world are actually closer to highly-evolved snakes than anything, and they're born in roughly the same way—the biggest difference is that ghost eggs, while still softer than most, are more rigid. In-universe, the word "Ghost" comes from an old language's word for snake, Ghos. Those of the incorporeal kind tend to be called spirits or specters. And you see those nubs on his shoulders there? Over time, those nubs will pop off and grow into the floating mitts all ghosts have! Ghosts in this world have mild telekinetic abilities, though this tends to be limited to manipulating the neurons of their detached hands—or prosthetics, should it come to that. At birth, they're little more than cute bumps that flap about as they slither around. One final nugget of knowledge for you: This picture, of Ghostie taking his first breath in the world, is one that his father Pete treasures dearly—he will never miss a chance to embarrass his son by showing it to any houseguests.
