Big Octorok

Big Octorok is the fourth boss that Link fights in The Legend of Zelda: The Minish Cap. He is located in the Temple of Droplets and was frozen by the power of the Water Element, and is starved because of that. Once Link unfreezes the Water Element, you also unfreeze the Big Octo. He eats the element, and retreats into the room behind him. He has the ability to transform into an Ice Octo, and can put out the light and fire large rocks at Link. It is not actually a Big Octorok, it's just that Link is very small.
