Before the first mission is completed, there is fog around the level. It disappears permanently when Plunder In The Sunken Ship is collected, and won't appear when the mission is selected again. The only way to see it again is to start a new save file.

Unagi's Tunnel
Unagi's Tunnel is the name given to the tunnel Unagi the Eel inhabits after Plunder In The Sunken Ship. Despite being unable to be entered, it is fully modeled. However, in some personalized copies, it is a new level.

Ghost Ship
There is a floating, collisionless clone of the sunken ship in the sky of Jolly Roger Bay, dubbed the Ghost Ship.
