References and Allusions to Yume Nikki in Yume 2kki

Last edited: September 14th, 2024

Catalog of potential references and allusions to Yume Nikki in Yume 2kki (tho some are officially confirmed or unmistakable). Focused mainly on worlds that strongly resemble or seemingly reference specific ones in YN. Mostly just for fun. Loosely based off of the Yume 2kki:Yume Nikki page, with some text directly coming from there or assorted Trivia sections. Thanks to Oh0kaYthen86 and WikiOdd for the suggestions.

Galleries are sorted alphabetically with YN worlds first, then 2kki worlds second. Worlds currently without an image of their resemblance will have a placeholder instead.

Barracks Settlement

Scorched Wasteland and Trophy Animal Land's Drum Folk Village contain desert settlements resembling Barracks Settlement.

Sculpture Park's Purple Forest Path contains several buildings with eyes that follow Urotsuki, similar to the Isees in the settlement's passage to Mural World.

Isees	Purple Forest Path buildings

Bleeding Heads Garden contains a room resembling the Seahorse Room and houses a similar looking NPC named Petriphant.

Block World

Color Blocks Void, Deep Red Wilds, Garden World, Radiant Ruins, Toy World, and Wooden Block World all feature isometric structures reminiscent of those in Block World.

Candle World

An NPC resembling a Walking Candle can be found at a table in Aquatic Cafe.
Pudding World resembles Candle World, albeit with pudding instead of wax candles. Inhabiting the world are walking pudding NPCs that resemble the Walking Candles.

Checkered Tile Path

Several areas are made up isometric tiled paths with a similar style to Checkered Tile Path.
- Notably, Closet Pinwheel Path is directly themed around closets like the one Closet Madotsuki is found in.

Closet Madotuski

Closet Pinwheel Path has a running theme of closets similar to Closet Madotsuki's (as mentioned in the section above). An isolated hidden area with a ghostly Urotsuki can be accessed from the Netherworld, paralleling how the original closet is only accessible from Lamp World.
The Haunted Cabinet in Nostalgic House contains a decapitated woman in the fetal position hidden inside, similar to finding Closet Madotsuki in the closet.
One of the rooms in Shadow Lady Estate has a wardrobe containing Urotsuki in a similar manner.

Pyramid

The pyramid that connects Psychedelic Graffiti World and Darkwoven Void slightly resembles the one that connects Candle World and Checkered Tile Path.
Indigo Pyramid Heaven is themed around pyramids resembling the one connecting Candle World and Checkered Tile Path.
- Additionally, this world is connected to Candle Block World, paralleling the latter's connection to Candle World.

Dark World

Dark Museum starts initially dark and requires the Lantern effect to properly see, similar to Dark World.
Obsidian Plains also requires the lantern and has several drawings made up of floor tiles like Dark World does.
While not requiring the lantern, Darkwoven Void is also modeled after Dark World and has floor drawings similar to it.

Dense Woods A

Pansy Path, Radiant Stones Pathway, and White Fern World have long paths that resemble Dense Woods A's Infinite Road with its Floyags.
Marshmallow Shallows has a hidden room with a Floyag-like creature.
The path from Surgical Scissors World to Neon Caves may be a possible reference to the Infinite Road, being a paved road with several of the titular scissors looming over the path in a similar manner to the Floyags. The track that plays also slightly resembles the music of Dense Woods A, containing a low sustained synth that tapers off into a reverb filled pause.

Music Comparison
Dense Woods A	Surgical Scissors World

Dense Woods B & Witch's Island

Several forest areas in Yume 2kki appear to be modeled after Dense Woods B and Witch's Island. Their specific style of silhouette treelines is paralleled by the majority of these areas.

Gallery:

[Show/Hide]

Shitai-san

Docks

Yume 2kki's own Docks, Rice Field, and Streetlight Docks resemble Yume Nikki's Docks. Like the original, these areas all have anglular, maze-like pathways over water as their main theme and design.
- Forest Pier contains a Docks-like section with these elements as well.
- Streetlight Docks has a fishing NPC similar to the Docks' Fisherman.
Nightfall Park has a small subsection resembling the Docks, which also contains a Strober-esque NPC. (see below section)

Strober

The Flashing Trombonist in Baddies Bar, the NPC in Nightfall Park that unlocks System Sounds #5, and the Candyman in Sugar World's Sugary Depths are all stick figure NPCs that resemble Strober.

Eyeball World

Azure Arm Land, Broken Faces Area, Beige Handful World, Hand Fields, and Sugar World's Sugary Depths are similar to Eyeball World, as they all have disembodied body parts littered throughout.

Broken Faces Area and Vomiting Mouths World have pairs of faces that directly parallel a set of Pier Monsters in Eyeball World.
A Pier Monster-esque creature named Bethany can be found in Cement World.

Eyeball World	Broken Faces Area	Vomiting Mouths World

Severed Blue Head

Abandoned Factory contains a strange face doorway that resembles an abstract version of the Severed Blue Head leading to Footprint Path.
Flesh Paths World features cartoonish severed heads similar to the Severed Blue Head, all of which also act as doorways.
Sugary Depths contains several enterable blob creatures in-between rigid arms, similar to the Severed Blue Head.

Face Carpet Plaza

Sparkling Dimension A, the intial area of Clawtree Forest, and Wooded Lakeside B's Gnarled Tree Plaza all resemble Face Carpet Plaza.
- Notably, Gnarled Tree Plaza features Shimako wearing a big hat, who uncharacteristically chases down Urotsuki in the manner of a Shadow Lady. If she "catches" her, she'll put the hat on her head and run away, rather than trap her in a dead end. Her inclusion in this area puts her in a similar role to the Toriningen chaser that can be found in Face Carpet Plaza.

Lizardman

NPCs in Snowy Apartments and Virtual City display text boxes with numbers when interacted with, just like the Lizardmen.
House of Vases contains a door design depicting a Lizardman.^[1]

Concept

While not visually similar to the FC Worlds, several other worlds in Yume 2kki share the concept of a retro game world with an artstyle shift with them. Notably, these have their own different styles, which are as follows:
- FC Caverns: Side-scrolling platformer, with gameplay similar to Super Mario Bros. 3 and other NES era platformers.
  - Additionally, FC Caverns C directly resembles VVVVVV.
- Mini-Maze: First-person maze. Notably, the mini-map for the area does resemble the style of the FC Worlds.
- Jigsaw Puzzle World: General 8-bit. Has both side and overhead views. Also has a unique alternate effect menu where Urotsuki walks across a grid.
- Retro Cartridge Game: Early video game consoles, like the Atari 2600, as well as other modern homages, like the hidden minigames in the Five Nights at Freddy's series.
- Topdown Dungeon: An NES Legend of Zelda style dungeon.

Forest World

Several forest areas in Yume 2kki resemble Forest World. Namely similar wide open spaces and angular rows of trees are used in these worlds.
- Evergreen Woods starts in an open section resembling Forest World before trailing off to more linear paths.

Namekuji

City of Liars contains its own version of the Footprint Path that connects to Nightfall Park.
Butterfly Sector's White Lily Path is also reminiscent of Footprint Path, being made up of small white flowers on a black background.

Goppa

The Bloody Passage in Ahogeko's House has a dark room with a Goppa-like creature dipping its tail in a pool of water. Chainsawing the creature's tail will grant Menu Theme #38 and light up the room, revealing its huge pained expression.
Emerald Cave contains a yellow, grinning creature that somewhat resembles a Goppa.
Foliage Estate also has a large Goppa styled creature, with a small bulb on its side that can be hit to inflict pain.

Ghost World

The building with the entrance to Wastewater Treatment Plant in Container Forest resembles Ghost World's large stone blocks.
Rainfall Ruins is very similar to Ghost World, as both are labyrinths of large angled stone blocks.

Graffiti World

Several areas in Yume 2kki resemble Graffiti World, either being voids made up of spreads of abstract tiles or having sections of them. Like the original, most of these tiles also make noise when stepped on and form larger pictures when viewed from above.

Guillotine World

Acerola World is very conceptually similar to Guillotine World, as both are small looping areas housing an effect, several chasers, holes in the floor, and an ambiguous exit.
House of Vases contains a door design depicting the Guillotine's face.^[1]

Some of the lockers in Ocular Locker Room contain small faces similar to the Closet Creatures in Guillotine World.

Hell & Mini Hell

Intestines Maze resembles Hell, being a large winding maze with animated borders, multiple world connections, and several chasers present.
Oriental Pub resembles Hell, being a large black and red maze. It also contains two red spinning 3D cubes that look and function like Nenrikido.
- Prior to version 0.114h, this area used a neon shade of red closer to Hell's.
Omurice Labyrinth resembles Hell, being a bright red and yellow extremely complicated maze.
Static Noise Hell, Oblique Hell, and 3D Underworld (which reuses the previous world's map turned upside down) are all directly visually based on Hell.
- All also contain a formation in the shape of some sort of shield figure wielding a staff, which directly originates from Yume Nikki's original Hell maze.
- The center of Oblique Hell also somewhat resembles a Henkei Shita, one of which can be found in the original Hell.
- The crossroad where Urotsuki starts off in Static Noise Hell is reminiscent of Mini Hell, complete with a transparent Urotsuki standing in the center.

Lamp World

Red Streetlight World resembles the concept of Lamp World, but with the added element of the streetlights having multiple distorted variants.
- Blue Streetlight World is in turn based on Red Streetlight World.

Madotsuki's Room

By interacting with the yellow-tinted window in the Never-Ending Hallway, the Madotsuki's Room event begins, with the player being trapped for a period of time in a glitched out version of Madotsuki's Room before the screen completely fades to static.
???-tsuki's Room in The Second Nexus, the Unknown Child's Room, and Urotsuki's Room all resemble the style of Madotsuki's Room
???-tsuki and Urotsuki also have a balcony attached to their rooms, like Madotsuki

KALIMBA

Channel #16 in the TV Room resembles the Kalimba channel.
The backs of the vending machines in Vending Machine Factory (as seen from one of the assembly lines) resemble the creatures from the KALIMBA event.

NASU

The unlockable FUJI minigame is likely a direct homage to NASU. According to Japanese traditions, dreaming of Mt. Fuji, a hawk and an eggplant on the first night of a new year is considered to be a sign of good luck. FUJI features Mt. Fuji itself, as well as hawks, while NASU features eggplants, thus complementing one another.

NASU	FUJI

The music that plays during the Madotsuki's Room event in the Never-Ending Hallway (see main section) appears to be a distorted version of NASU's BGM.

Mall

The Music Box Creature on the couch in Bottom Garden resembles O-Man.
The room with the Menu Theme #23 in Blob Desert is similar to the part of E-Man's Room with the menu theme Toriningen.

Space contains several real photos of planets in a similar manner to Mars, including a playground on the Moon that shares a similar angle to the original.

The Second Nexus is very reminiscent of Yume Nikki's Nexus, having a traditional layout made of doors.

Effect Eggs

The Child effect can be found in a large egg in Hourglass Desert's Pyramid Maze with Urotsuki's shirt pattern on it, similar to the effect eggs Madotsuki can drop in the Nexus.
Several worlds by Wataru and noildoof contain large eggs that give Menu Themes and are similar to the effect eggs.

FACE

The Wardrobe Face event in Board Game Islands is a direct reference to the original FACE event
- In addition, the face-like door which triggers the event seems to take inspiration from the scrapped FACEtile door found in the files of older versions, as it opens in a similar manner.

ああああああああ Event

An あ can be found on the wall in Cipher Keyboard where the grave accent key would be on a standard QWERTY keyboard.
One of several pieces of text Glitch Hell can change Urotsuki's name and status in the menu to is "ああああああ".
Graffiti Passage contains a section covered with あ's. At the end of it is a single red あ that floods the area with more of them and adds a red tint to the screen.
While navigating Kaprekar Number Zone there's a random chance that there will be a red cube in one of the dead-ends. Interacting with it will trap Urotsuki into an inescapable area with a flood of glitched red numbers.
If text events are on, Monochrome Mansion's Monochrome Fields contains several buildings with red あ's on them.
- Additionally, a schoolgirl NPC can be found here that will trap Urotsuki in an isolated area filled with the same あ's if chainsawed.
A room on the top floor of Monochrome School contains a chalkboard filled with あ's overlooking frantically moving girl trapped behind desks and chairs.
Red Black World contained a set of red tiles with 死 (shi, death) on them. Walking onto the middle of the tiles trapped Urotsuki in an area full of 死 similar to the あ event.
Channel #6 in the TV Room features a shadowy Urotsuki with a bloodied chainsaw over a scrolling background of bright red あ's.
In Underground Runological Warehouse, graffiti of the hiragana character わ (wa) can be found in one of the rooms. Equipping the Chainsaw or Marginal effects will transform it into a red あ.
Seishonen's room in Urotsuki's Dream Apartments contains a paper that displays various red hirigana, which are each tied to specific ranges of variable #44. When said range is between 0 and 61, an あ will be shown.

House of Vases contains mask-like creatures on poles that resemble the face on the floor of the Stabbing Room.

Pink Sea

Several areas resemble Pink Sea, featuring similar water and rock formations. Often these will have "shoal" as part of their English names.
- Cones like those near Poniko's House are also common in these areas, also appearing in otherwise unrelated worlds like Abyssal Garden and Illusive Forest.

Poniko's House

Candlelit Factory has a small room where interacting with a bloodstain on the wall will turn the lights on and off like Poniko's lightswitch. After using it a certain amount of times, the NPCs in the room will slowly be replaced with bloodstains and a door will appear.
Seishonen in Urotsuki's Dream Apartments resembles Poniko, having a similar sprite and eye type. There's a 1/31 chance that the room will glitch out upon entering, similar to randomly getting the Uboa event when flicking the lightswitch.

Big Red

In addition to resembling the Sewers, Abandoned Factory has an event where Urotsuki is eaten by a large red monster, similar to Big Red, and taken to a dark world with pinwheels and a multicolored panorama, similar to Windmill World.

Big Red	Abandoned Factory

Interacting with a red NPC in Streetlight Docks will show a close up of them that resembles Big Red. This event essentially plays out the opposite of Big Red's. The NPC is shown with its mouth closed and Urotsuki inside. Using the chainsaw will cause it to open its mouth, letting her access an isolated section of Angler's Depths.

Big Red	Streetlight Docks

Sewer Drawings

A wall in Mini-Maze contains graffiti with a style similar to the drawings in the Sewer.
Red Nail Passage contains abstract drawings viewed in the same manner as the ones in the Sewer. Interacting with a hole in a wall will cause the picture to "expand" out towards the screen.

Sky Garden

A section of Glowing Tree Path has a realistic scene of a distant city where two UFOs chase each other in the sky above, likely in reference to the similar cliffside area in Sky Garden.

Madotsuki

Like most fangame protagonists, Urotsuki's sprite is directly styled after Madotsuki's.
- One prototype design for Urotsuki more closely resembles Madotsuki, notably having short pigtails and a pink/red outfit. This design and a couple others can be found as masks in Binding Site.
Most of the rooms of the Dressing Room have an unreachable mannequin in the center bearing the window from Madotsuki's shirt.
The secret room in Hourglass Desert's Pyramid Maze containing the Child effect contains a rug which depicts the window pattern worn on Madotsuki's shirt. The same area plays a cover of the menu theme of Yume Nikki and has a character that somewhat resembles Madotsuki herself on the wall, holding a sign depicting the window pattern.
Darkwoven Void contains a set of tiles that form the window pattern found on Madotsuki's shirt.

Mouth Monsters

Sanctuary has white open-mouthed blob creatures that somewhat resemble Yume Nikki's Mouth Monsters.
