Ezlo

Ezlo was originally a Minish wizard himself, but when his apprentice, Vaati, stole from the wizard a magic hat that could grant wishes, he was transformed into a cap. Link saved this "cap" when he was being attacked by monsters in the Minish Woods, and together they departed on a journey to stop Vaati. At the end of The Minish Cap, once Vaati was defeated, Ezlo changed into his true form once again.
