I've made a top 3 list of my races:
1. Deku
Deku Scrubs are unique races in the Zelda series and I wish the had a bigger role in the Zelda games, but that isn't so yet. Nintendo can do much with the Deku Scrubs and they just don't do it.
2. Mogma
Mogma's are just awesome by looking at them, they have a cool look, they have a cool theme. They have almost every thing, that's why Deku's are cooler.
3. Lokomo
Since the Lokomo's only are seeing in Spirit Tracks, they are unique to the series, that's why I like them. They come forward by wheels, BY WHEELS?! They can just drive to any destination, gimme that thing and I have the time of my live.
