Critter: Young Chippie

This is a Chippie. Chippies live in complete darkness at the bottom of every System's Register.
They live in nests which they build out of old bits and pixels, which they also use to upgrade themselves with.
Their feet make clicking noises when they walk.
The young ones are scared of light, but more developed Chippies can attach lightsources to themselves to improve the search for material.
