The Moon Lord's Hand Sees All (...the Food You Are Not Eating at Lunch)
The Terraria game resurfaces as a favorite with our kids on a regular basis. Hanging out with a couple of friends at camp reinvigorated their interest recently.
I don't know much about the Moon Lord beyond the fact that his face resembles Cthulhu and he has a glowing eye in each palm. For whatever it is worth, the eyes in his palms are oriented vertically and are not like the "Hamsa" hand common in eastern religious iconography.
The Terraria wiki says: "Moon Lord is a Hardmode, post-Lunatic Cultistboss. It is Terraria's final boss."
There's a lot more to this boss, thematically, and visually. I just went for the aspect that was easiest to draw on a napkin.
