Butterfly Forest

The Butterfly Forest (蝶, Chō, Butterfly) is a dark place accessible from the red butterfly in Red Lily Lake. As the name suggests, there are lots of butterflies floating around their corresponding butterfly drawing on the ground.

Features
The area has 7 different colored butterflies (some of them might not appear), each teleporting to a different area. The same white NPC from Fantasy Library is also wandering around.

The red one takes you back to Red Lily Lake.

The Light blue one takes you to a place filled with bubbles, with a blue bubble NPC that if interacted with teleports you to Cutlery World.

The green one will take you to a secluded cliff-lke area with a waterfall on the background. Approaching the edge will pan up the screen, showing more of the waterfall. A black bunny is here and will be stepping away from you. He reacts to various effects, the most notable being: The Invisible effect will turn him into a light blue floating orb. the Fairy will make him transparent and he will run away from you even faster. The Glasses will be shattered as soon as you equip them. The Cripple effect will turn him white and he will "heal" you, unequiping it. The Child effect will also turn him white.

The yellow one takes you to a small lake with some fireflies, the blue one takes you to the Constellation area. The Pink one takes you to a set of rainbow stairs.

The white butterfly will teleport you to a room that changes color in 3 tones with each visit. If the room is black and white, approaching the wall will make Urotsuki say her "no/don't" quotes. If it's yellow nothing happens, if it's blue you may proceed forward and find yourself "on top" of a book you can enter, taking you to a white room with a girl playing the piano. Interacting with her will make her play a new tune for you. Killing her will turn the room darker, the piano tune will change along with the background. If you go out to the book, it will also have changed to a red tint and you will be unable to return back to the butterfly. Going back inside the room, there will be nothing but a hole in the ground that takes you to the piano in Snowy Pipe Organ.
