The Harvest Festival is a fall holiday that lasts for about a week (Thanksgiving week). During this time, the Festival Grounds get rather bustling with activity: Nana comes to sell various fruits from the zikkle orchards, Tiffy and Bruno sell Harvest Festival themed things (or was it just squashes? *can't remember), Liluye sells forest themed foods, and Iffy buys squashes from you for bits, the amount varying each day.
The Harvest Festival was not yet celebrated, though the mystery basket, trubble, and fall avatar were released.
On Thanksgiving Day, users were able to click a button which gave them a mystery basket.
This was the year all of the NPCs and Festival Grounds were introduced.
