Charlie



The Grue (called Charlie by Maxwell) never reveals itself. It only attacks at night, in complete darkness, when absolutely nothing is visible. Prior to its attack, the characters will give some sort of warning, such as "What was that?" Moments later a slashing sound is heard and the character will take 100 damage and 20 Sanity loss. This will continue to happen until a light source is found, or until the character dies.

Light Sources
The following light sources will prevent the Grue from attacking:
 * Fire (campfire or burning objects)
 * A Torch (while equipped)
 * A Miner Hat (while equipped)
 * A Pumpkin Lantern (on the ground)
 * A charged Lightning Rod
 * A cooking Crock Pot
 * A Heat Stone at full charge
 * Willow's flame
 * Willow will suffer from great Sanity loss while in total darkness, between flames.
 * Abigail's glow
 * It's difficult without getting hurt or killed by Abigail herself.
 * Fireflies' illumination.
 * Coming close to them will cause them to disperse. If players walk away, they will come back almost immediately, making it possible to "hop" between two or more patches of fireflies and survive the night. It can even be done with just one patch, walking in and out of repeatedly, although this is more difficult and the player suffers greater sanity loss.

Trivia

 * The Grue's name is a reference to the iconic monster from the game Zork.
 * The damage that the Grue does in one hit (100 damage) is close to 66.6% of Wilson's maximum health (150 health), possibly alluding to the mark of the beast - "666".
 * Since Suprise! Story Preview Test, Maxwell refers to the Grue as Charlie. Maxwell says, "Its getting Dark, Charlie will be waking up soon!"
 * Grue is the name of the sound of a blade slashing in a very high pitch.
 * Spoiler!  Kevin said in a pre-alpha livestream of the Caves update, that Grue(aka Charlie) is a girl.

Bugs

 * If you enter a Worm Hole just before the night sets, Grue will not attack you when you come out of the other side. (This bug is stopped when going into light and then back into darkness again.)
