Effects/Items
There are six effects in Broken Bottles.
Glass Shard is like the knife effect in Yume Nikki. It is Dokutsuki's weapon and used to kill NPCs. It is located in Broken Glass World. Go through the brown door south of the Nexus door in Boom World. Interact with a box at the top left of the room. Go through the new door that appears, and interact with the bleeding severed hand next to the crying figure.
Skull is a purely cosmetic effect. It turns Dokutsuki's head into a rotted, yellow skull. It is found by interacting with a skull and bones in Boom World. It is located southwest of the Nexus door.
Bandages is a purely cosmetic effect. It puts bloody bandages around Dokutsuki's head. It is located in the Hospital. To find this effect, go to Boom World. Enter the red building, go down the path and break the giant bottle by interacting with it. Navigate through the maze until you find a door to the Hospital. Take the only door here, the topmost door in the next room, the accessible door on the right side of this hallway, and a door up from here; navigate to the bottom-right corner of this corridor and enter this new series of rooms. You will be able to interact with a woman to get the effect, whereupon a Chaser will appear.
Voiceless is a purely cosmetic effect. It puts a gag around Dokutsuki's mouth. In Faces World (the second door in the Nexus), there are two gagged yellow faces with the word "WHAT" above them. Go between these faces and enter Words World. Interact with another gagged face in this world to receive this effect.
Clock-Head makes Dokutsuki's head look like a clock and makes her body become a part of it. Her hands and feet become the hands of the clock. You can use this effect to see the true form of the blue wisps in this world. You can find it in the Clocks area, found in the Library, which is accessed from the Airport. This effect is known to have a glitch that makes the Wake Up function disappear from the menu. Yikes!
Medusa makes you look like the Gorgon Medusa. You can activate this effect using the SHIFT key and freeze NPCs. You can find it in the Medusa area after disactivating all the hands and talking to the woman statue in the Library area.
Key 1 is received from the triangle in the bottom left corner of the Dream Courtyard.
Key 2 is received from the pink security person at the Airport, and allows you to board one of the flights and view the Crash event.
Bus Ticket is found in the room near the Bus Station filled with monsters, and grants access to the Bus Ride event and, consequently, the Airport.
Events
Bus Ride
Approaching the driver of the second bus in the Bus Station and sitting down will make the bus go dark, rumble, and drive the player to the Airport.
Plane Crash
Similarly, upon getting Key 2, the player can board the furthest plane in the flight area of the Airport. Upon entering the plane, a woman will tell Dokutsuki the flight is full and that she must get off, urging her to use the bathroom first. Using the glass shard effect, the patrons lining in front of the bathroom can be killed to get access to the latrines, though these have no effect. Finding the pilot at the front of the plane initiates a rather rude conversation in which he tells you to board the next flight. When the player at last leaves the plane to reenter the waiting area, an announcement will play, indicating that the plane has crashed. The room will suddenly turn red with a change of music and all the NPCs there will become chasers.
