Forum:Skull Kid and Saria's Song

I see that everything says that Link taught Saria's Song to the Skull Kid, but if you play a different song, or play it wrong, then the Skull Kid will say:That's not quite Saria's Song. And when you do play it he says:You know Saria's Song! We should be friends. And those sound like he already knows it, it's just you have to play it and he will want to be your friend, in my opinion, he wants to be your friend because you obviously know Saria.
