quite a curious and interesting animal. yes? it is quite the shape shifter. as long as you see it's star like fur and split tail, you should be good.
however, there are precautions when depicting luca's form.
see below:
notice that in (most) images of luca, it's tail and fur are multiples of 2, or easily divided by half of it's points.
(it is the fur 'fractal' as it splits itself in half each time.)
if luca has fur that are in clumps/ points of one or 6, it will result in a visual error for luca.
this usually is not a big deal, but since luca manifests in these forms one draws of it, it hurts quite a bit in odd numbers for too long.
it prefers twos (sometimes, for ease, it will prefer threes.) it's fur is stiff and bristly like a hedgehog, or shorthair cat. it can morph it's body and makrings to any animal, but cannot change color besides it's lightest color (the monitor 'green' like a LCD, can turn BLUE or CYAN.)
