I've gone from occasional pony art to crazy alternate character interpretations and art thereof.
Oh well, at least I'm doomed with ponies. Couldabeen doomed without ponies. That's worse, you see. Myes.
Anyways, Pinkie Pie is clearly a ghost and has been since episode one. How else do you explain her crazy supernatural powers? She cah-learly haunts people, appears in mirrors, enforces spirit oaths, and comes from a 'rock farm' that is more than a little sinister.
