Haunted Shipwreck

Haunted Shipwreck, or , is the Ghost House course of Sparkling Waters in New Super Mario Bros. U. The concept for the level is similar to that of the Sunken Ghost Ship from Super Mario World. It is unlocked via completion of Giant Skewer Tower and its own completion unlocks Above the Cheep Cheep Seas and Urchin Shoals.

Layout
Unlike the other Ghost Houses in the game, this one takes place in a ruined ship, and some sections are underwater. The course contains many hidden walls and secrets, including a secret exit. Boos and Circling Boo Buddies are recurring enemies in this course.

 * Star Coin 2: In the room with the Circling Boo Buddies, above a group of them.
 * Star Coin 3: In the room which consists of hidden walls, one platform above the entrance door.
