Keaton begs to Link...

Excuse me master!

I did not want to attack you

the dark power made me

Vaati has returned for revenge and will use the dark power of Majora's Mask you beat!

What do you mean yellow fox?

If you don't drink the special milk from Lon lon ranch at midnight on three days you'll become int the character there forever...

An example if you wear Keaton mask without that special milk you'll be a fox like me
