Poniko
Background
Poniko lives alone in a conical house on a southern island within the Pink Sea. Much like Madotsuki, she is the only inhabitant of her space. In her room, she wanders aimlessly and does not react when interacted with normally, though she responds to the Knife and Stoplight effects. Using the Cat effect causes her to perform a small stomping animation.
If Madotsuki interacts with the light switch in Poniko's room, there is a 1/64 chance that the room will transform. Poniko will disappear, replaced by Uboa. Approaching Uboa will result in Madotsuki being transported to Uboa's Trap.

Appearance
- Looks:
Poniko is a young girl with a distinct appearance, characterized by her blonde hair styled into a neat ponytail. Her facial features include rosy cheeks and striking blue eyes. Notably, her gaze is consistently directed to her left, often giving her an expression that appears annoyed, dismissive, or disinterested. This subtle detail in her demeanor adds to her enigmatic presence.
- Regular Clothes:
She wears a green long-sleeved shirt, which contrasts with her fair complexion and blonde hair. Her outfit is completed with a brown checkered skirt, adding a touch of simplicity to her overall look. Her style is modest and practical, reflecting a casual appearance.
- Special Clothes:
Poniko’s footwear consists of red shoes that bear a striking resemblance to those worn by Madotsuki. While their significance is never explicitly addressed, the similarity may symbolize a connection or parallel between the two characters. Despite her otherwise plain attire, this small detail adds an intriguing layer to her visual identity.
Personality
From the game
Potentially Easily Annoyed: Poniko seems to have an annoyed expression on her face when Madotsuki meets her,
In the Manga Interpretation
- Admired Figure: When Madotsuki first encounters Poniko, she views her with admiration, wondering if Poniko will be her friend and complimenting her fashion. This initial perception suggests that Poniko leaves a positive impression, evoking curiosity and hope for companionship.
- Malicious and Cruel: Poniko's demeanor shifts drastically when she transforms into Uboa, an unsettling figure that haunts Madotsuki. As Uboa, she shows no remorse, attacking Madotsuki, stealing her effects, and trapping her in a nightmarish state. Her actions highlight a vicious and unforgiving nature.
- Vengeful and Determined: During the story's climax, Poniko uses Madotsuki's stolen powers to confront Seccom Masada-sensei, beheading him as Uboa and bringing his remains to Mars-san. This act demonstrates a ruthless resolve and willingness to carry out extreme measures.
- Self-Sacrificing: Despite her aggressive actions, Poniko ultimately chooses to save both herself and Madotsuki. Rather than pursuing further violence, she destroys Madotsuki's dream diary with the Knife effect, collapsing the dream world to put an end to the cycle of violence.
Relationships
Madotsuki
From the game
Poniko's relationship with Madotsuki varies greatly on interpretation, in the base game, going off scene alone there is not much to gather from both of their relationship as Poniko just seems to be another NPC.
From the Manga Interpretation
Madotsuki initially admires Poniko upon their first encounter, expressing curiosity about whether Poniko will become her friend and complimenting her appearance. This admiration quickly turns to fear and resentment when Poniko transforms into Uboa and relentlessly attacks her. By attacking Madotsuki, stealing her effects, and trapping her in a nightmarish state, Poniko cements herself as a threatening and malicious figure in Madotsuki's mind.
As the story progresses, their relationship becomes even more complex. After using Madotsuki's stolen powers to attack Seccom Masada-sensei, Poniko is tasked with exterminating Madotsuki. However, instead of following through with this violent act, she chooses a different path. By destroying Madotsuki's dream diary, Poniko sacrifices the dream world to free both herself and Madotsuki from their destructive cycle. She notes to do this because she doesn't "want to be leave the dream world as a 'good girl'".
Despite this act, Madotsuki’s lingering hatred manifests in the form of a monstrous figure that ultimately consumes Poniko.
From the Novel Interpretation
Initially, Poniko serves as the narrator of Madotsuki's journey through the dream world, acting as an observer and guide to her progress. However, once Poniko encounters Madotsuki, the focus shifts from Madotsuki's journey to Poniko's own quest for understanding. Poniko becomes determined to uncover the reason for her presence in Madotsuki's dream and seeks a way to escape. As the story unfolds, it is revealed that Madotsuki is not the dreamer but rather another dream character within Poniko’s own subconscious mind. Madotsuki exists as Poniko's shadow, representing the manifestation of Poniko's unborn child, an embodiment of her maternal fears and anxieties. The true nature of the real world is never explicitly shown, but it becomes clear that Poniko's concern for the safety of her child created the dream world as a form of mental escape. This revelation adds depth to their relationship, as it is not just a matter of Poniko trying to help Madotsuki, but rather Poniko trying to overcome her own fears and trauma associated with the unknown future of her child.

Other
Standard Tactics
- Dream Entiy Interpretation: Poniko does nothing unless Madotsuki keeps flicking the lights off and on, presumably annoying her to the point where she transforms into Uboa. By this point, they make leaving impossible without directly walking into them.

Weaknesses
- Dream Denizens Weaknesses (If using the Dream Entity Interpretation): Dream Denizens cannot enter into the other worlds within the dream[43][44].
- Unique Weaknesses: Nothing notable.
Note
While it is never outright confirmed in the game that Uboa and Poniko are the same being, the fact that Uboa pops up in her spot and does not appear if she is killed makes it heavily likely that they are the same person.
Trivia
- Due to the nature of Uboa's event and the disturbing appearance of the character itself, Uboa is often hailed as one of the reasons Yume Nikki grew in popularity in the West. Uboa saw heavy usage in Internet memes and edits during the early 2000s shortly after the character's discovery, typically depicting the character in a more humorous fashion.
- Due to its popularity, Uboa's character and event are commonly parodied or imitated in various Yume Nikki fangames. The character itself has also gone on to make cameos in various Internet media and appears to have inspired the designs of characters such as the Mystery Man from Undertale and White Face from IMSCARED: A Pixelated Nightmare.
- The sound effect that plays when the player touches Uboa is the same one as when a Toriningen traps the player.

- If Poniko is killed using the Knife effect before triggering the Uboa event, then Uboa will not appear in the room. Due to this, the two can be inferred to be the same character and Uboa is simply an alternate form or appearance of Poniko (or vice-versa).
- Uboa also appears in the exact location Poniko was before the lights are switched.
- Uboa will not appear if Poniko is killed. This forces Madotsuki to pinch herself awake or use the Medamaude effect.
- The background noise that plays when Uboa appears is the same as the music for Guillotine World slowed down by half.
- Uboa's name originated from a 2channel post describing how to activate Uboa's event. The initial post simply reads the instructions to activate the event before adding "ウボァー" to express the shock the event may give the player.
- The phrase or "scream" used to express the event in the post references a line of dialogue from the character Emperor Mateus from Final Fantasy II, with the phrase also being a 2channel meme at the time of the post's creation.
- Additionally, the characters that make up Uboa's name (ウボァ) do not normally go together in Japanese, with the effect of the name being similar to Cthulhu or Astfgl in its "wrongness".
- In the manga, Uboa is given a ponytail and movable arms, likely to more closely resemble Poniko. Its body is also much more blanket-like, sporting visible ruffles on its body.
Different Interpretations From Official Media
As Yume Nikki is an exploration game with largely no story, the game is left up to interpretation, though there are official Yume Nikki creations that have their own interpretations that can be dervied from.
- Manga Interpretation: The Dream World is also a shared collective conscious of girls trying to turn them into "good girls" with characters like Poniko trying to find a way to esacpe the dream world[45][46][47][48][49]. The Uboa transformation is a result of the girls wanting to be let out, creating an unsightly lump to apepar around them, eventually fully forming over them as they do not accept the changes of the dream world[50].
Codex Statistics Questions
Q: Shouldn't she have 2-C Environmental Destruction for causing the entire dream world to be destroyed?
A: The dream world is an abstract realm that can't properly be tiered, though even assuming it could be, she does this through specifically destroying Madotsuki's notebook[51], indicating that this is a weakness of the dream world rather than a tier for her.
