|~ The game when in a dark cave, warning the player of a Grue|
The Grues are monsters that appear in the text adventure/interactive story video game series Zork. They spawned a extremely popular phrase in video game history and are extremely dangerous. Few have survived a grue attack (according to the game) and notoriously stay in the darkness, never seen in the light.
