From Connecticut's Comic-Con 2012, taken with my iPhone: It's the Powerpuff Girls a la Walko! I aged them up a bit, and here they are. It's hard doing such conceptual stuff at a Con... I wish I had more time to really re-imagine them!
There was actually an episode where they were "normal", and had noses and fingers and stuff, so I guess that implies normally they don't have fingers or noses or ears or anything. It's so strange how not-real the PPG are and how nobody notices until they're made to look "normal".
