Jack's Patch is an area located somewhere near the Farm in South of Cajar. It was a seasonal area, open for a week on and after Halloween. During that time Jack would transport any who wished to collect turnips to and from his patch, as well as providing a quest to help him regain his lantern. At present it is only possible to reach Jack's Patch by using a Pumpkin Mask. One mask will be able to teleport you to Jack's Patch once a week for ~30 minutes.
