Really rad skull shape, especially with the dithering. And I learned something knew! Interesting to see this inspired by a real land mass

It's a magic eye illusion — you are meant to cross your eyes to see a three dimensional image, in this case it is a large "3".
It can be tough to see. I recommend looking at a more standard magic eye illusion first, then try that technique on here. At the end of the day though, it is a novelty and a fun way to see what is possible on the Game Boy. The trick of it all is what is fun about it.
Oh, and don't fullscreen it too look at it, that can make it more difficult. The size it is when looking at it on the submission page or the project page itself should be a comfortable scale to see the illusion.
