Yume Nikki:Effects

Effect eggs in The Nexus

There are 24 'proper' effects in Yume Nikki. Each 'effect' changes Madotsuki's appearance and some provide special abilities. None of the effects are mandatory to progress through the game, so they can be collected in any order (except for 'poop hair', which requires either Yuki-onna or Umbrella) but many optional events and locations are unreachable without them.

The effects are scattered throughout the dream world, and some are more easily found than others.
Gathering all 24 effects is considered to be the primary objective of the game, and only when all effects have been gathered can the player see the game's finale by leaving them all in The Nexus and waking up.
Some effects are found in certain locations whereas others are received from interacting with characters.

Instructions

See the instructions again

Appearance: None

Passive Effect: None

Action: (Equip) A basic tutorial on how to play the game

Location: Madotsuki starts with this effect

Practical Uses: Learning how the game works

• This is the only effect that can be used in the real world and cannot be dropped as an egg in the Nexus.

Pseudo-effects

These are actions that work like effects, but are not added to Madotsuki's inventory and are not required to finish the game.

Chair

The chair in Madotsuki's dream roomcanbe ridden when Madotsuki sits on it then pulls the chair away. Instead of writing in her diary, sitting at the desk and pressing Z (facing the desk) will let Madotsuki scoot the chair around her bedroom. She can ride the chair to almost anywhere in the dream world (albeit very slowly), but will not be able to get off it until she returns it to her desk.

Crick in the Neck

The only involuntary effect, Madotsuki has a random chance of waking up with a crick in her neck. She will constantly be looking left. As she does with no effect, pressing 1 will cause her to sit down. She is unable to write in her diary or play NASU. Going back to sleep and waking up again should solve the problem.

Madotsuki will not dream that she has a crick in her neck, and yet there is a matching FC world spirite.

Speed Glitch

A useful glitch that quadruples Madotsuki's walking speed. Although Madotsuki will appear as her normal sprite (except in the FC world), the glitch will be active. The bicycle is the most commonly used effect for this, as it allows for quadruple speed. The Speed Glitch is an oversight caused by allowing the player to use the menu in the chair.

Instructions

1. Sit in the chair in Madotsuki's dream room
2. Open the menu with X
3. Equip the Bicycle
4. Press down, then Z to exit the chair.

The glitch will now be active. The effect will disappear if you equip any effects. Madotsuki will sit if 1 is pressed, but the other action will happen as well (e.g. with the bike, the bell noise will play).

Hyperspeed Glitch

Instructions

A related glitch that is slightly more complicated, but allows the effect to stack allowing for movement eight times faster than the walking speed, which is equal to that of the Candle World Toriningen.

Instructions

1. Sit in the chair in Madotsuki's dream room
2. Open the menu with X
3. Equip the Bicycle
4. Press Z to ride the chair
5. Ride the chair into the Nexus
6. Press 5 to drop the bicycle effect, then pick it back up
7. Open the menu (You should hear the 'unable' sound effect), and equip the bicycle
8. Return to the bedroom. There will be no chair at the desk.
9. Go to the desk and sit down on the invisible chair, then press down and Z to get up.

Noclip Glitch

Disables most collision, allowing Madotsuki to walk through objects and walls.

Instructions

1. Sit in the chair in Madotsuki's dream room
2. Equip the knife effect
3. Press down, then Z to get off the chair
4. Quickly (while Madotsuki is moving) press 1 to switch hands with the knife

This will allow Madotsuki to walk through anything with any effect equipped, however some loading zones don't trigger.

Unused effects

These are effects that exist in the sprite sheets and have limited handling in the game's coding, but are not accessible in the game. These may be added in a future version of Yume Nikki.

Blindfold

Appearance: Madotsuki wears a black blindfold

Speculation: Some kind of effect that affects what Madotsuki can (or can't) see.

Grayscale

Appearance: Madotsuki appears in monochrome.

Speculation: It's possible this was intended to be the appearance Madotsuki takes on in the White Desert, as there is no counterpart FC world sprite. If this is the case, then it's likely that it was dropped since it could cause confusion as to whether the White Desert was really white, or whether the effect was a result of a problem with the player's perception of it (as is the case with old monochrome photos).
Allowing Madotsuki to retain her hues makes it clear that the player's vision is normal and that the world is white.

Another idea is that this is an effect that you get from the White Desert that makes Madotsuki (And possibly the room you are in) monochrome.

Do note that this spirite is in fact used for Madotsuki's Ghost.

Will o' the Whisp

Appearance: Madotsuki transforms into a blue flame-like spirit wearing the Triangle Kerchief.

Speculation: A possible alternate form considered for the 'ghost form' of the Triangle Kerchief, as spirits are commonly depicted as blue wisps in Japanese folklore.
