Phil with the oddly shaped head has always looked like a thumb. But, early on in his "career" he looked more like a regular thumb.
It's kinda surprising to see how gaunt he looks shortly after arriving at the WAkahndo. He went from looking almost kinda sorta normal to looking like he was one chemo treatment away from giving up the spook. Is Phil's agoraphobia THAT bad? I've known a recluse or two that still have a better skin tone and disposition than him.
