I always kind of appreciate it when there's just a single one of something in a video game for no explained reason

the single red snifit in mario 2, the single green rupee (in a chest) in quite a lot of zelda games, that kind of thing

there's nothing particularly special about them other than the fact that there's only one of them

@Felthry Ooh I like that sort of thing too~

@BatElite if you're curious, I know for a fact that A Link to the Past, Ocarina of Time, and Wind Waker each have a single instance of a green rupee in a chest (ignoring the randomized "chest games" in ALttP and OoT), and I'm pretty sure Twilight Princess does too but that could be wrong. I don't know about any of the others; I strongly suspect the GB/GBC games do *not* and I doubt BotW does but I don't have proof of that

@Felthry Doesn't Link's Awakening have several unique enemies? At least the GB(A) ones, I don't know if the switch one does too.

@BatElite I was just talking about the single green rupee

LADX, the GBC remake, does have a few unique enemies but they play a role in a sidequest (namely the sidequest of "kill all golden enemies")

@Felthry I don't remember that sidequest. :O

@BatElite it was only in the GBC remake and I don't think it gave any big reward, we'd forgotten about it entirely until you mentioned it
