He's too big for the box, and is due for a brand-spankin' new sprite to better reflect the nature of a 'copycat'.

He's animated in Unitale, and I haven't quite learned how to anchor his tail correctly, so that's what's goin' on there.

If you want the mod (which is a basic one that isn't quite finished), I suppose you can take a look. It's got some messy code..
