The Ghost Ship is a creepy and disorienting place. Your goal here is to find Tetra, who is trapped somewhere within. The ship is filled with Phantoms, powerful enemies that cannot be defeated with your sword. Instead, you must avoid them or stun them with your Boomerang. The ship's layout is designed to confuse you, with doors that lead to different areas depending on which side you enter from. Pay close attention to the map and any clues you find. You'll need to solve a series of small puzzles, often involving switches or moving objects, to open new paths. Eventually, you'll find Tetra, but she's been turned to stone! You'll also encounter a mysterious old woman who gives you a hint about the Temple of Courage. Your objective on the Ghost Ship is not to defeat a boss, but to gather information and a key item that will lead you to the next dungeon. After finding Tetra and getting the hint, you'll automatically be transported back to your ship.
