That's a good question but it has no answer, you see we are never told what happens to Navi at the end of the game.
You'll see alot of fans on the internet arguing about what happens but none of that is canon. But if you want theories check out some Zelda fan pages, although it would be a waste of time.
since link is not a kokiri, he is not assigned a fairy, that is why after saving hyrule, navy goeas away
After the Ocarina of Time she left
Navi leaves link at the end, why else would he get a different fairy in the next one. Navi leaves him because he is no a real kakiri child
Link is on a Quest to find his old friend Navi after parting ways. (Navi is his fairy from Ocarina of Time)
In the beginning of the game there is a flashback. It shows Zelda giving Link the Ocarina of time for his journey to find Navi. In the beginning you see Link on his horse in the woods. That is his journey to find Navi until skull kid brings him to Termina.
you go to IGN or any of the many many gaming sites that have a walk-through and follow its instructions. or you talk to navi and she will likely tell you what to do.
if you mean avgn stuff its a parody of navi the annoying as hell firefly in the legend of Zelda ocarina of time
you press home on your keyboard
Ocarina of Time: Navi Majora's Mask: Tatl Twilight Princess: Wii Remote Cursor Phantom Hourglass: Celia Hyrule Warriors: Proxi
grab the ocarina that zelda threw and go to the temple of time where you can get the master sword
It would be the legend of zelda ocarina of time were you get to travel to young link to older link in skyward sword you can hit rocks that are supposed to be made from the ocarina in ocarina of time
you get the ocarina as a kid. . .you get the fairy ocarina from saria when you try to leave the forest after beating the deku tree level, the ocarina of time comes after you beat jabu jabus belly... if u need the ocarina of time head for the castle, and it will go into a screen play where kid Zelda throws it into hyrule castles moat. dive down to get it and the go play the time song in the temple of time
go to vizzed retro arcade and choose n64 and search Zelda to play ocarina of time
the answer is she actually does leave him. don't forget only kokiri get fairies and link isn't a kokiri. the great deku tree only sent navi to protect link until the evil was gone.
