I'd very much like not to discuss Twilight Princess until I get around to playing it. Which will be in about four weeks. (Curse you, Nintendo Australia!)

I had Zelda's "true form" as some sort of bird as well - only it was, in reflection of her strongheaded personality, a wild duck. But: as Zelda became more and more consumed by the will of Chaos (through the Triforce of Wisdom, I imagined her form would change, subtly as well.)

I like the sound of Turtle Link.
