The Mouth Monsters are a group of three NPCs that appear in Mural World and Underground World. They all give different effects when interacted with.

Appearance

The Mouth Monsters, as their name states, have large mouths that take up a large amount of their body, which overall resembles a severed head. They have red lips with square-ish and gapped teeth, and their bodies are a dark brown color. They sport a head of hair that matches the effect they give: one has brown hair, one has blonde hair, and one has its hair done to resemble a cartoon poop shape.

Overview

The Poop Hair Mouth Monster as seen in the manga.

Curiously, each Mouth Monster is found wandering around near a blood splatter on the ground, similar to the one seen in Eyeball World, which helps the player navigate them. No Mouth Monsters are ever seen where there are other types of NPCs in the vicinity.

Two of the Mouth Monsters are found wandering around in Mural World. One of them gives the Long Hair effect while the other gives the Blonde Hair effect.

The last Mouth Monster can be found in Underground World, though a blazing fire blocks the path to them. The Umbrella or Yuki-onna effects will be needed to put out the fire. Once Madotsuki reaches this Mouth Monster, they give the Poop Hair effect upon interaction. Strangely, the Mouth Monster in Underground World will always move towards Madotsuki, unlike the ones in Mural World, which move randomly.

All Mouth Monsters show the standard reactions to the Knife, Cat and Stoplight effects. Otherwise, they do not do anything once their respective effects are obtained.

Trivia

• It is possible that the Mouth Monsters are based on the Template:WP, a yōkai that initially appears to be a normal woman, but is revealed to have a mouth in the back of her head that emerges from her hair.
  • They could also be based on the Template:WP yōkai, a small creature covered entirely in thick hair that prefers to live in dark, damp areas.
• In older versions of Mural World, all three Mouth Monsters were found in the area due to Underground World not yet being in the game, making it the only place to house three effects.
