The Legend of Zelda: The Minish Cap/Characters/Ezlo
Ezlo is a character from the The Minish Cap He is Primarily a Craftsman of the Minish race but was turned into a Duck like hat by the Wind Mage Vaati. He serves as a Guide throughout the Game and helps Link with Various Tasks.
Ezlo is first encountered by Link being attacked by two octorocks inside the Minish Woods. Upon saving him Ezlo decides to accompany Link on his quest. Because he is unable to move very fast, having no legs, throughout the adventure he rides on top of Link's head like a hat.
Later in the game, it is revealed that Ezlo was once a highly skilled Minish Craftsman who created a magical cap with the power to grant wishes. However, his young apprentice (Vaati) stole the cap and used it to turn himself into a powerful sorcerer and transform Ezlo into his hat-like form.
At the end of the Game Ezlo is transformed back to normal and gives Link a new hat as a parting gift.
As a Minish he was able to create a magical cap that granted wishes, but he can do very little in his hat form.
Upon finding a Minish portal (A disguised object that allows one to change size) Ezlo is able to transform Link to the size of a Minish to let him explore areas where only someone the size of a bug can. Ezlo is very knowledgeable and is able to aid Link with information on the various places around Hyrule. He can also be used as a parachute when Link Jumps into a Whirlwind.
He is also one of the few Picori that can speak Hylian without use of the Jabber Nut.
