@linkster7: I am pretty sure I remember that from the 80s as both a plot point in some movie(s) and the type of nonsense that was spread by D.A.R.E.-type drug "education".
@onkel: I never had an NES, so I didn't play it back then, but I think that at the time, from what I've read online, that was probably a big thing and a surprise to many. Nowadays, I don't think that would be such a big reveal, it would come across as weird to hide that fact until the endgame.
