Stickcraft 3
Stickcraft 3 is a minecraft type world, where you put stickman all over the world doing stickman stuff.
Over time, pixel arts have been created representing a monument, either one of a creeper,
or the logo of the image board, 4chan.
It has also begun to popularize the use of spam with the camera emoji (📹) to later reveal that there is an underground room with a person watching the cameras.
Actually no one plays Stickcraft 3, its popularity is only from the World of Day, but now no one remembers this world..
