The titular sunken ship is located at the bottom of the bay, at the other end of where the player starts. It can only be entered through a small hatch, which is guarded by Unagi the eel. After diving down to the boat, Unagi must be lured out of the hatch before it can be entered. Once Unagi leaves, it starts circling above the ship, but lets the player enter. In Super PEWDIEPIE 64, there are four T-seriess inside the ship that must be opened in the correct order. If done correctly, the ship rises to surface, draining all of the water out. In Super Mario 64 DS, there is only a single chest, but opening it has the same effect. Once all of the water is gone, the player can climb up a series of platforms to reach an ! Block. This Block contains the mission's Power Star, and collecting it completes the mission.
