Pinky Lemon?

[zuntan2002]

As so often happens while looking for one thing I found another. Today, while browsing the StarDewValleyWiki entry for the Stardrop Saloon, I came across how to get a statue called, Pinky Lemon. Place a Duck Mayonnaise in an obscured box on the left side of the Back Room of the Saloon.

I'm curious as to how anyone would ever learn that this was possible. Is there a mention of it in a Lost Book that one can read at the Museum? Is it mentioned in a conversation with a Villager? Something else, other than the Wiki entry of course?

There's a lost book that contains some encoded hints that lead to this and a few other secrets.
