The "Snapper" is a creature I saw in a dream(nightmare). They're about 4.5 feet tall. Their skin is a very thin layer, tightly covering muscle and bones. Pale white and transparent enough to show blood vessels. This one here was my trying to redraw it but it's so different I decided to make it an Alpha or adult.
They are blind and deaf. They walk around with their heads close to the ground and snapping and clicking their teeth, hence the name.
In the dream they didn't react to seeing us, nor did they to the sounds of our feet. They only noticed us when the group I was with started walking away to escape. They don't run very fast. I woke up when I realized they were staring at me and thus I was f***d.

On top of their heads is some sort of organ I imagine they use to detect life. A friend came up with the idea of being like sharks, that they see the electrical impulses made by our muscles moving.
