15 Creepy Video Game Easter Eggs of All Time

Shadow People of Hell Valley– Super Mario Galaxy 2

Not much is known about the Shadow People found in the Shiverburn Galaxy level in Super Mario Galaxy 2. While in the level, if you look up at the right spot, you’ll find the shadow outline of three people, watching you. There’s no way to get to their location, and they never move. Gamers eventually opened the game’s files and discovered the texture for these people was labeled “HellValleySkyTree,” with Hell Valley being the Japanese term for the Shiverburn level.
