Pirate Ship Theme
From Nookipedia, the Animal Crossing wiki
The Pirate Ship Theme, or Pirate Theme as it is referred to in Wild World and City Folk, consists of a small number of unconventional, nautical-themed furniture items. Pirate items are obtained from Pascal in Animal Crossing: Wild World, Animal Crossing: City Folk and Animal Crossing: New Leaf. Pascal will be at any of the bridges in town on random weekdays from 6:00 a.m. to midnight in Animal Crossing: City Folk. In Animal Crossing: New Leaf, he appears if the player catches a scallop while diving.
Once his rant is over (in Wild World), he will leave, but not before giving the player an item from the theme. If the player has a scallop in his or her pocket (in City Folk), he will ask for it. Once he obtains the scallop, he will, in turn, give away a pirate item. If his request is denied or a scallop is not in the player's pocket at the moment, he will jump off the bridge and float away.
Unlike other special themes, pirate items will be available through the catalog once Pascal has given them to the player.
