I always wondered why Zelda's Lullaby is played in the ending to send Link back to being a kid. Then I realized that Zelda talks about "returning to the way you were supposed to be" and such - playing Zelda's Lullaby by a shattered sign restores it to normal, so why can't Zelda's copious magic power do the same for Link himself? Talk about hiding your Foreshadowing well!
Zelda's Lullaby is also Shiek's theme arranged slightly differently and at a different speed. The music was also in disguise.
This may be unintentional, but the third magic circle of Mars from the "Key of Solomon" looks somewhat like the Triforce. Its purpose is to cause discord that ensures the fall of one's enemy. When Ganondorf tried to take the Triforce, it split apart, and the separate pieces going to Link and Zelda is what led to his defeat.
Kasuto is the only town from Zelda II not to have a Sage named after it, it is also the only one that has been explicitly stated to be destroyed in the past, and had been rebuilt and hidden as New Kasuto.
Playing The Legend of Zelda: Ocarina of Time as a child, I always found it badass how Sheik could just disappear in a flash of light. Not until later did it hit me that he's actually throwing a deku nut - and then he disappears while Link is paralyzed.
It could also be considered a "Crowning Moment of Funny" if you think about it. While Link, the invinicible, ultimate hero, is paralyzed, Sheik could very easily just walk away nonchalantly, make a funny face at Link or something on her way out. - Shradow
When I first played Ocarina of Time, I noticed that Navi's description of the Beamos was very unhelpful. She says, more or less, "I bet it doesn't like smoke to get in its eye!" Beamos can only be killed by bombs. For the longest time, I just thought Navi's description was a really unclear way to say you needed to use bombs. Years later, I realized the description was probably intentionally bad and phrased that way as a Mythology Gag to the very first game's Dodongo Dislikes Smoke, which also refers to "smoke" when you're supposed to use bombs. -Epiblast
Many a player has got frustrated with Navi's apparently completely useless advice in the Great Deku Tree - "Yes, Navi, we know how to open a damn door!" Except that there aren't any buildings that have doors in Kokiri Forest... and if Link was left there as an infant, then he's never actually seen a door before, thus making Navi's advice... completely relevent and useful for him.
