Jack

Jack is a pumpkin wearing man that will appear on Oct. 31st at 6:00 p.m. - Nov. 1st at 1:00 a.m. The trickiest part is that all the citizens in your village will be dressed as Jack. The villagers will chase you & if they catch you will ask for candy. If you give them some they will let you pass (leaving the acre will result in them chasing you again) but if you do not, they will turn your clothes into rags or your items into Jack in the boxes or Jack O'Lanterns. So, keep your items at home and wear a pair of clothes you hate so if they become rags, you won't care, or wear one of your own designs.

Jack and Tortimer are the only people who will not chase you. Visit Tortimer at the Wishing Well to recieve a model of Katrina's tent. Run home and put it in your house, then continue to hunt for Jack. Candy should be stored in spare mail slots temporarily until you can establish whether or not you are speaking with Jack. He will give you a piece of the Spooky Theme. If you want to collect them all, keep visiting him until you have the complete theme.

Return
Jack, along with all the other holiday characters, was absent from Animal Crossing: Wild World. He does, however, as confirmed on 31st October 2008 on the Animal Crossing: City Folk Japanese website, return, along with Halloween, Candy, and the Spooky furniture set.

The Spooky Furniture Set
Jack gives a piece of furniture every time the player gives him Candy. All the furniture pieces are shaped like and resemble pumpkins or Jack O'Lanterns. They are orange and, like all holiday-excluive furniture sets, score very highly with the Happy Room Academy.
 * Spooky Wall
 * Spooky Carpet
 * Spooky Bed
 * Spooky Bookcase
 * Spooky Lamp
 * Spooky Wardrobe
 * Spooky Chair
 * Spooky Dresser
 * Spooky Vanity
 * Spooky Table
 * Spooky Clock
 * Spooky Paper

Jack O'Lanterns, Jack-in-the-Boxes and Ragged Shirts can be arguably considered part of the Spooky set. There is also a Spooky Shirt, which is not given to the player by Jack, but either by Gracie or by Wisp.
