Jingle is a special visitor in the Animal Crossing games. He comes to visit the player's town on Toy Day (Christmas Day) to deliver presents.
Although he is meant to be sneaking into houses and leaving presents, if you talk to him, he will give you a special treat, a rare piece of Jingle series furniture! Furniture in this series can only be obtained from him. He will ask you two questions and, he will either give you furniture of carpet, depending on how you answer! Sometimes, if you change your players outfit, you can fool Jingle into thinking you're a different person, and he may present to you, another present!
Jingle is meant to be like Santa Claus. He even wears the same hat that Santa wears, and will occasionally say "Ho ho ho".
