In Animal Crossing and the other GCN games, Toy Day occurs on the 23rd of December. Tortimer will be waiting at the Wishing Well and will award the player with a gift. If the player is a boy, they will receive a model of Gracie's car. If the player is a girl, they will receive a doll.
Main: Jingle; see this article for more in depth information.
In Animal Crossing: City Folk, Toy Day occurs on the 24th of December. A reindeer named Jingle will give the player gifts on this day. The player can change their accessories for more gifts. This holiday is supposed to be Christmas, and the animals will talk about it for weeks beforehand. The player will also get a letter from Jingle beforehand.The festivities begin at 8 in the evening, and end at midnight.A good method is for the player to buy as many shirts and accessories as thy can before Toy Day, to avoid being recognized by Jingle. To decide what gift to give to the player, Jingle will ask a few questions about the player's interests. If the player answer the first question, for example, as things to step on, the player is more likely to get the Jingle Carpet, but the opposite (Jingle Wall) about things to lean on. The player can sell the items because they are very expensive. The Jingle Series is like the Bunny and Pavé series. Don't wear the same outfit or he will not give the player a present. Jingle will be hiding in non-lit houses, and occasionally outdoors. Normally, the player cannot go inside unlit houses. But on Toy Day, there are no signs on doors, and the player can enter. Sometimes on Toy Day, Jingle may be inside.
In Animal Crossing: New Leaf, Jingle appears in the player's town on December 24th. He will say that he doesn't want to deliver the presents, and would rather it be done by someone dressed as Santa Claus. During the month of December, Santa's outift (Hat, Beard, Coat, Pants, and Boots) are for sale at the Able Sisters and Kicks shop. If the player has bought the outfit, they may talk to Jingle to receive a Magical Bag, which holds the presents of the villagers living in the town at the time. Earlier in December, the villagers will drop small hints about what they want for Toy Day such as furniture and clothing. On Toy Day, while wearing the Santa costume, villagers will think that the player it is actually Santa and will ask for their present. Once all of the presents are delivered, the player may talk to Jingle to receive a Festive Wreath. If all presents are delivered to the correct villagers, the player will get Jingle's picture in the mail on Christmas day.
