For "Michijo" of FurAffinity.
They're obviously very tiny, and actually run by clockwork.
The species does not have one singular form. As you can see, they come in different mutated states,
Different shapes and sizes, all furry with bronze/copper, which is covered mostly in Patina.
The inside of the head, the gears and joints have none because they leak oil
They have no limit to their range of motion, so they can twist, turn and bend as they please.
