Big Octos are giant squid that lurk under the Great Sea in The Wind Waker HD. There are six, each in its own square of the Sea Chart, and you can always spot one by the large flock of seagulls circling above it. When you sail close, it surfaces in a whirlpool and starts pulling you toward its mouth. Destroy all of its eyes with arrows, the Boomerang or bombs from your cannon before you reach the middle, or it swallows you and spits you out at the edge of the square. Beat it and it leaves a treasure behind to salvage.

The Octo Chart marks all six on your Sea Chart. It's a sunken treasure at Northern Triangle Island, found with Treasure Chart 26. Do the Two-Eye Reef Octo early: the bigger Magic Meter makes the Deku Leaf, magic arrows and the Flight Control Platform game much easier. See Heart Pieces for the other pieces of heart.
