Tingle Island
Tingle Island is one of the islands of the Great Sea in The Wind Waker. It is the home of Tingle and his brothers Ankle, David Jr., and Knuckle. Link will make several visits to this island during his adventure for the sole purpose of asking Tingle to decipher the Triforce Charts he has collected.
A Piece of Heart can be retrieved from the bottom of the sea by defeating a Big Octo located near this island.
