Honestly, there's insufficient evidence to say for certain either way. It could be either. I'm leaning to Droog because it's the simpler explanation (Occam's Razor go) but there is a decent amount of evidence for it being Jack, like possibly Bilious Slick still being destroyed after the scratch (http://mspaintadventures.com/?s=6&p=006206) though this could also suggest that it's a different frog. Let's wait and see rather than assuming the other side is full of wallies.
As for the update itself, oh snap. I wasn't expecting that to happen.
