Plot summary
Wirt, Greg, and the frog travel to the town of Pottsfield. Along the way, they "rescue" a talking bluebird, Beatrice, from a thorn bush. In return, Beatrice offers to guide them to Adelaide, "the good woman of the woods", who can help them get home. In Pottsfield, they find the residents celebrating a harvest festival, all dressed from head to toe in pumpkins and straw. The brothers are cautioned that they might be in Pottsfield "too early". Enoch, the village leader, charges them with trespassing and disturbing the peace, sentencing them to a few hours of manual labor.
The brothers end up assisting with the harvest. As they dig holes in a field outside the village, Wirt becomes afraid the Pottsfield residents plan to actually kill them and bury them there. Instead, skeletons emerge from the graves they dug, dress themselves in pumpkins, and are warmly welcomed by the community. Wirt realizes that all of the Pottsfield residents must be skeletons. As they are allowed to leave Pottsfield, Enoch tells Wirt, "You'll join us one day." The brothers follow Beatrice to Adelaide.
