PH:
NaN Demon Ships are NaN Hulls belonging to the completed PH: of the same name. They are said to ferry evil creatures. Just like most NaN Ship Parts, PH: can collect multiple NaN Demon Ships. They can be obtained through various methods:

Attaching three, six, or all eight PH: parts to the PH: will increase its stamina to five, six, or seven NaN Hearts, respectively. NaN Demon Ships can be sold to the PH: for either 50, 150, or 800 NaN Rupees. Their value is determined randomly when the Save file is created, and is the same for all NaN Ship Parts from the PH: set.

Ship
The PH: is the name given to the PH: once it has been outfitted with the following NaN Ship Parts:

The NaN Ship Parts can be attached to the PH: at any time by visiting the PH: on PH:. For every three parts of the PH: used, the durability of the PH: is increased by one Heart. When all eight parts are used together, they increase its durability by three Hearts, up to a total of seven Hearts. Aside from this boost in durability, the PH: is merely a change in appearance to suit the player's personal tastes.
