Pirate ship
The Pirate Ship is a rabbit hole like object that appeared in The Sims 2: Bon Voyage, the sixth expansion pack for The Sims 2. Sims can do numerous things in the object, incuding exploring different sections of it, and public woohooing in it. A large one can be seen on the shores of Twikkii Island, in back of the Twikkii Beach Hotel.
