There is a total of Six Big Octos lurking around someplace in the Great Sea in The Legend of Zelda: TWW. When you are looking to find the Six Big Octos, You need to go to an Island and look for some seagulls in a ring. As you get closer to them, the water will swirl, like a water tornado thingy and the giant beast will appear from the water. When you fight these Big Octos, you should use a weapon that can go a great distance, as a boomerang or your bows and arrows, When you use your boomerang or B&A attack its eyes.
