Halloween

'Halloween  is a real-life event that occurs on 31st October, and is celebrated by the animals of the players' town in Animal Crossing. Throughout October, Candy is stocked and sold in Tom Nook's shop, taking the place of some of the Flowers. This Candy is used for trick-or-treating. From 6pm until 1am on 1st November, the player can go around his/her town, where the villagers are all outside. If they see the player, they will chase him/her. If he/she is caught, they will be forced to give Candy to the animal. If they do not concede Candy, they will be punished by having their clothes or their items transformed.

Jack is the King of Halloween, and all the villagers, including Tortimer are dressed like him - a dark blue cloak and a Jack O'Lantern mask. Jack and Tortimer are the only two that do not chase the player, which makes them easy to be told apart. Tortimer will give the player a Katrina's Tent Model. Jack can be spoken to as many times as the player desires, in order to receive the Spooky furniture set.

Halloween was absent from Animal Crossing: Wild World, but returns in Animal Crossing: City Folk. Unlike the original, not all the villagers go out on Halloween night, and those who remain in their houses are able to be trick-or-treated on.
