Is it King Dodongo? Dimitri the Dodongo? Dodongo's as a whole?
Great idea.... but you're waaaay off track. Still, these do go back just as far as Dodongos do. Here's the slightly edited riddle again: "You don't wear me, nor am I green. Those that once fed me now are useless. I cannot find a place to rest. What am I?"
The first sentence is key, and is a special play on words~
The moblin? It would make sense, he is red, and wants food, and he has no place to rest.
Again, a really good idea, but no. It is a fairly common enemy though. I think the best way to crack it is if you think of this enemy's behaviour patterns- it can't find a place to rest because it is both technically undead, and because it's always on the move. It flies, then rests, then starts flying again etc.
Also the first sentence is key, it's a play on words. It might be clearer if I said "I'm not green, no do you wear me", because that's the same order as the name it is a play on words of. Think what enemy's name involved something green and something you would wear, in that order!
No... it wouldn't happen to be Keese would it?
That would be as far back as a dodongo, but it couldn't be could it?
You're in the right period though, but no. It is something that can fly though!
And gee, I didn't think it would be this hard a riddle c:
And nope, it's not a Bubble either. But you're all close...
