Stardew Expanded Note 18 (Spoilers)

[ehyder]

Another Expanded question - The FAQ on the mod gives some pretty vague information about Secret Note 18. I have been digging around and had no success. I will dig around where the vague clue suggests for a bit more but if anyone has more specifics I would appreciate it. I have had trouble getting the other secret notes to work (pathing maps) since objects have been moved. I finally did figure these out (19 and 20) but 18 is causing me a lot of frustration.
