Effect Eggs

Effect eggs in The Nexus


The Effects as they tend to appear in the Manga

There are 24 proper Effects in Yume Nikki (not including the Instructions/Tutorial). Each effect changes Madotsuki's appearance and some provide special abilities.
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.

The effects are scattered throughout the dream world, and some are more easily found than others. Some are found by touching particular objects whereas others are received from interacting with characters.
While none of the effects are mandatory to progress through the game, many events and locations are unreachable without them. They can be collected in almost any order, except for the 'Poop hair' effect, which requires either the Yuki-onna or Umbrella effects. It is also recommended to get the Lamp effect before attempting to get the Knife or Witch effects, which require traversing dark areas.

Descriptions and names on this article are given in the order of fan translation first, official translation second.

The chair in Madotsuki's dream room can be 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.

(guide on Youtube)

Crick in the NeckEdit

Looking Left
Look left sit

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 sprite.

(guide on Youtube)

Effect GlitchesEdit

Speed GlitchEdit

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.


  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 GlitchEdit



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.


  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 GlitchEdit

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

  • Note This will also work with the umbrella effect


  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.

Broken Instructions Edit

A somewhat convoluted glitch that allows you to be able to move, and enter a new area while the instructions are open which leads to a variety of glitches.


  1. Equip the frog effect in the chair.
  2. Go to the area you want to do this. It has to be somewhere where you can just walk into a different area.
  3. Press 1 and you should see Madotsuki sit down, then jump back up.
  4. Equip the cat effect. (Can also be done with an egg drop in The Nexus)
  5. Wait for a little while and the game will force you to sit down.
  6. Press the X key once (only once) a few seconds after being forced to sit down.
  7. Press 1 and the menu should open after the animation for the cat effect is finished.
  8. Open the instructions (don't close them).
  9. Wait a few more seconds and then press 1.
  10. You should hear the same sound as when you use the cat effect, and be able to move freely.
  11. Walk into the walk in area mentioned before.
  12. Press the Z normally to reopen the instructions, however pressing Z while equipping effects will not reopen it.

Sub Glitches Edit

Invisible Madotsuki: This glitch is a side effect of broken instructions, and requires no extra setup beyond what's listed above.

BGM storage: Another side effect of broken instructions. The way this one works is that when you open the instructions the music stops, but it starts again after you close it. If you close the instructions in a different area it will take the music from wherever you opened the instructions and play that. This is because the game still has it stored.

Glitched movement: Glitched movement is a glitch that occurs when you close the instructions while sitting down. Your movement will be cycling between 4 of the sitting animation sprites. Left is the first sprite and then it continues in order clockwise.

Broken save: This is a glitch that makes a save file unplayable. To do this glitch do broken instructions and wake up with the instructions. Press 1 so you are sitting, then press Z to reopen the instructions. This will give you glitched movement. If you save with glitched movement your save will be unplayable.

Broken witch event: If you do broken instructions and close the instructions in the witch event the game will put you in the center of the witch event where you can work around. This works because the game stores Madotsuki when you open the instructions, so if you close the instructions in the witch event the game will think it needs to put you back into the game in the same way you were when you opened the instructions. This causes there to be two Madotsukis you control at the same time. As well as enables menu use.

Video demonstration:

Unused effectsEdit

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.



Appearance: Madotsuki wears a black blindfold.

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

This sprite was used in Yume Nikki 3d (a Yume Nikki fan game).



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 sprite is in fact used for Madotsuki's Ghost.

Will o' the WispEdit

Will o' the Whisp

Appearance: Madotsuki transforms into a 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 (They're called "Hitodama" [☀人魂, ひとだま]).

Note that the sprites below the mugshot have (to date) only been found in version 0.04, but are still unused in that version. It appears that it would have been able to change colors.
