Video I'm talking about?

A couple of years ago I had watched an animation video on YouTube about how Herobrine (a mob from Minecraft) was created. It started out that he had a brother, Steve. (I don't think his name was Herobrine yet.) One day they went in this cave to dig. When they had gotten really far in where there was lava, Steve thought they should head back. And they were just about to, when Steve's brother saw diamonds! He dashed around the edge of the lava and started digging it, but he slipped! And fell, slowly burning in the boiling lava! Steve was horrified! His brother had just died before him. Once there was no more struggling, Steve went home, lifeless as a zombie. Ever since (for some reason) Herobrine haunted Steve! Please tell me the name or sight if you know!
