We were discussing in the thread New update for Thimbleweed Park: build 938 where to use an object somehow needed to play the arcade games.
I’ll give you a few hints. My suggestion is to stop reading them when you realize what to do. Let me know if you need more information.
Hint 1: the easter egg involves another object that has always been in the game since its first version.
Hint 2: this other object has something to do with a previous game by Ron Gilbert.
Hint 3: the game in question is “The Secret of Monkey Island”. If you haven’t played this game, let me know.
Hint 4: this other object can somehow lead you to a place.
