Read the comic here.
The "Green Donut" is indeed the Old-Donut-Head Regenerated. Don't freak out overmuch over it - it's a minor plot point I needed for a later strip. (As well as sort-of resolving the "why are there two Donuts" issue)
I normally try not to alter the character's facial expressions - but I needed an "KOed" face for today's strip. It's a photoshop edit - although I'm seriously considering trying to mimic it in real life. (All I did was remove the open eye from a standard Whiskey face while leaving the eyelid line)
