New Twilight Princess Video (minor spoiler?):
How Link gets his sword.
If you can't watch it but want to know whats on the clip, highlight to read:
Link gets his first sword by "stealing" it from the village swordsman.
You can now use your sword as you run.
There seems to be more possible combos with your sword.
Cuccos (chickens) are both brown and white now and can swim like ducks.
