Farmer Gricoller is the owner of the Tithe Farm in the Hosidius House in Great Kourend. Gricoller is an experienced horticulturalist, as his work dealt with various methods of enriching crop production primarily through fertilisation.
Gricoller is the author of Farmer Gricoller's Farming Manual. Using the book on him results in additional dialogue in which he states that he wrote the book a long time ago, and that he told the publisher that the book should not be monetized in order to share the knowledge freely. However, he further states that was a bad decision, due to him aging and unable to afford hiring workers.
- During My Arm's Big Adventure, My Arm mentions eating a farmer before taking the manual. Before Farmer Gricoller's official release, it was assumed he was ultimately devoured by My Arm, but the release of Great Kourend proves that it may have been another farmer who My Arm ate.
