Chapter 4 begins by hopping into a wedding where the collectable, a masked man, doesn't appear to be in any of the paintings, despite the hint icon indicating that he's in all of them. Also, despite the fact that you can walk right up to a hole in the painting, you can't fix it for some reason. This is all because you're meant to find the masked man hiding in just one of the paintings. Once you find him in one, he'll run away and appear in another. This continues until you've found him in all six paintings sequentially. You can't pick the order like you could in previous chapters. After you do this, the game will funnel you in the direction of the ending. For anyone who does not want any of this guy's locations spoiled, stop reading now and go back to enjoying the game! For everyone else, read on!

The order of the masked man's appearances is shuffled every time you play the chapter. We'll go in order starting with the painting with the hole.

In this painting, he's hiding behind the table to the right of the candlesticks and jugs laying on said table. His hat and one of his eyes will be visible, but he will occasionally be completely obscured by the lady in the hat as she rocks back and forth.

Proceeding to the right, in the painting with two skeletons playing tug-of-war, the masked man will be hiding in the crowd by squatting down in the bottom right corner behind the table. You can identify him by his navy blue hat poking out.

Next, in the painting with the animal orchestra, the man will be hiding in the very bottom right of the painting. Once again, only his hat will be sticking out.

To the right, in the painting with the two overstuffed men, he'll hide behind the one on the right. It'll look like the man is just wearing a navy blue hat unless you look closer.

Next up, in the painting where a couple is vomiting into each other's mouths, the masked man will be hiding in the bottom right corner again, wedged between the two other heads that are always down there. His hat will be visible.

Finally, in the painting with two skeletons fighting with cleaning supplies, counting from left to right, the masked man will be hiding right in between the third and fourth man wearing red. His hat and eye will both be visible here.

After you find all six, the game will prompt you to click on the hole in the original painting. After that, just proceed in a straight line and you'll be led directly to the last clickable object. There's really no room to get lost from here here, so I'll end the walkthrough here in order to preserve at least a little bit of the game's experience for you all. Thanks for reading!
