Some notes about the dark/chaos/mirror world

[Nimono]

I have a couple of ideas:

1: Make Link and Zelda change according to the Sacred Realm (Dark World) principle.
2: Make them change according to the Chaos World principle (that is, they turn into monsters).
3: Make them change according to the Mirror World principle (That is, they turn into whatever is the OPPOSITE of their hearts).

Or....

Make Link and Zelda change according to the Sacred Realm/Dark World principle until you get Moon Pearls for them, but after that... The Chaos World principle kicks in (implying that the Sacred Realm's properties override those of the Chaos), thus making them monsters until they gain a NEW item. Maybe call it the Chaos Rune?

Being that he comes off so timid and withdrawn, it would make sense that he'd become some sort of creature that held that kind of protection. Whereas the original is more of a protection from social situations, the later is one from physical harm, making it fit well with the theme of the Sacred Realm (Emotion becomes Reality).

But hes also energetic thats were the bunny came from but how about link turning into a hedgehog, like him being withdrawn he can curl into a ball, and being energetic (the energetic part comes from sonic the hedgehog of course.) he could go through small openings in HH form and roll down slopes or even climb them with claws and the protection of the spikes on his back I think he fits a hedgehog more than a turtle what do you guys think?
