So I was looking through some of the beta pictures (and articles) of both OOT, and MM, and I found this little gem in the latter game:
http://www.zeldauniverse.net/zelda-news/majoras-mask-contains-two-hidden-unused-cutscenes/Apparently these were cutscenes involving Link and the Great Fairy, that were not used in the final cut. One involves Link doing some exercise, where he morphs into Fierce Deity Link, and gets the enhanced health. And the other is the Great Fairy teaching Link how to spin attack. And by teach, she's
physically forcing him to do the attack. Which is also accompanied with a "Do as I say" comment, according to the translated Japanese text. I may be reading too much into this, but it's so easy to take the wrong way with how both characters are "positioned" in the spin attack one. It just looks.... wrong, for lack of a better word. I mean, I knew the Great Fairy was strange, but not on that level.

So if you want another reason to never set foot in another Fairy Fountain again, there you go. Just, make of this what you will.
