Star Isles

Five-Star Isles is one of the isles of the Great Sea in The Wind Waker. A Piece of Heart can be retrieved by looking for a submarine, going inside, and defeating all the enemies within. Link can obtain a second Piece of Heart by using one of the Treasure Charts found in Windfall Island (specifically, Treasure Chart #33).

This island is also a recurring destination of the Ghost Ship.

Fishman's hint on Five-Star Isles: ''Have you seen it, small fry? ...The Ghost Ship? Cause it's real. It's even been seen here, in these very waters... On nights when the crescent moon faces down... That's when horror rises...''

Trivia
