Hey so I was replaying Link's Awakening for the umpteenth time recently and I got past the 8th dungeon and was moving on to the wind fish egg. However when I pulled out my Ocarina to play the ballad of the wind fish only the 3rd song was available and ballad of the wind fish and Manbo's mambo were both gone and not selectable. I was wondering if anyone else has heard of this problem/ knew a way to fix it.

Sounds like a glitch. Try resetting.

If that doesn't work, just use the Doghouse glitch to cheat your way to the final boss.
