I really like the Rito from Wind Waker. I'm not sure how I feel about the fact that they have both beaks (as noses) and mouths... shouldn't they be one and the same? But anyway, I thought they were an interesting species, and I want to be able to fly!
I would love to be a Zora! I would spend my days swimming everywhere and exploring the depths of the sea. The only downside of being a Zora would be that I wouldn't be able to stay on land for long periods of time.
I'd be a Kokiri! The child in me would finally be able to shine again. I love the lightheartedness of the Kokiri people, but hopefully I'll live in the time period of OoT because I would hate to be a little plant creature like in Wind Waker.
