The 404 Challenge was performed by Stampylongnose in 2012. This challenge is no longer available in both PC and Xbox, however Stampy had a chance to play it before he updated the game, since the next update removed the challenge. The series was put in private for unknown reasons.
The series was set on a Minecraft seed which had the 404 challenge in. As Stampy spawned in the world, he had to gather materials in the surface during daytime, and as it went to nighttime, he had to break a gravel pit and travel down the caves for the rest of the challenge. The challenge ended as Stampy died (like Hardcore Mode).
