Yume Nikki:Mouth Monsters

The Mouth Monsters are a group of 3 NPCs that appear in the Mural World and Underground World.

They are small creatures consisting of a mound of hair and a large mouth with red lips and wide, square teeth. Each has a unique hairstyle and gives this to Madotsuki as an effect.

Curiously, each Mouth Monster is found wandering around near a blood splatter, one for each individual. What this represents, as with everything else in the game, is a mystery. There is a theory, however, that it shows that Madotsuki might be a cannibal, but it is highly unlikely. Furthermore, no Mouth Monsters are ever seen where there are other types of NPCs in the vicinity. The implication may be that they have eaten another creature and wear their hair as a trophy, which perhaps explains why Madotsuki can take it off them.

The Poop Hair Mouth Monster is a little different from the others. Not only is it found in a separate location to the other two, but its behaviour is slightly different, too - it will always move towards Madotsuki, whereas the others move randomly. Additionally, the Poop Hair effect has a different (1) Action to the other hair effects.

Interaction

All three give effects that change Madotsuki's hairstyle when interacted with:

• The one with brown hair gives the Long Hair effect
• The one with blonde hair gives the Blonde Hair effect
• The one with the hairstyle that looks like a fake dog poop gives Madotsuki the Poop Hair effect.

They otherwise ignore Madotsuki, but show the standard reactions to the Knife, Cat and Stoplight effects.
