Black Butterflies are strange creatures that have appeared in several of the Cube Escape games. They are entirely decorative, but their appearance usually marks the start of the game's surreal elements.
Cube Escape: SeasonsEdit
In the Spring, there is a parrot, Harvey, kept in a cage. After feeding her with bird food, she will lay a black egg. The egg can then be boiled in hot water and placed in an egg cup. Cracking the egg with a spoon will release black butterflies, before uncovering a black cube.
Cube Escape: ArlesEdit
After van Gogh goes into his own ear, a single black butterfly appears, and follows van Gogh as he travels ventures into his ear. It goes as far as the wall with two doors, but stays behind in the ear when van Gogh enters either door.
Cube Escape: Case 23Edit
During the investigation, Detective Dale Vandermeer finds a Rusty Lake Mental Health flyer, and a newspaper detailing an exclusive trip to to Lake. After calling the phone number, he experiences a brief blackout, before regaining consciousness. The Woman's body is now hanging upside down, and attempting to interact with her causes black butterflies to come out of her mouth as she rises up out of view, and more black butterflies congregate at the ceiling. They form a number code to the Woman's safe, which contains photos to the Rusty Lake archive.
Cube Escape: The MillEdit
In the top floor of the Mill, there is a clock next to a TV. When the TV is switched on, it shows the dead body of the Woman from Cube Escape: Case 23. After the body rises up out of view, it is transported to inside the clock. Opening the clock releases black butterflies, and the player can then move her body to the main room.
Cube Escape: ParadoxEdit
There are three bottles hidden inside a globe. The middle bottle holds a caterpillar which can be fed with a twig. Going into a cocoon, the caterpillar comes out as a black butterfly and flies away. The player finds the butterfly at the lounge chair, where there is a stitched tear surrounded by small maggots. Cutting away the stitches allows the player to take some string needed to get a glass eye from a bottle.
After the player has become a Corrupted Soul, there are four black butterflies in the room. Touching three butterflies causes silhouettes of multiple Dales to be seen through the walls. By touching the fourth butterfly, it turns into a key to unlock the door.
