It has been three weeks since Pete and Zoey arrived in Round. During that time, they've slayed giant turkey monsters, started a pizzeria, and organized peace between the town of Greenlake and a group of raccoon bandits known as the Trash Pandas.

As a united Greenlake prepares to celebrate a holiday known as Harvestfest, a dungeon portal appears near town. Where dungeons offer a opportunity for those seeking wealth, the monsters found within the dungeon present a threat to Greenlake. To make things worse, the portal's appearance has drawn the attention of the Adventurer's Society and the moderators. With the extra attention on the tiny town, one thing becomes clear. Greenlake will never be the same again.
