Suicide Mouse is a {{Creepypasta}} about a supposed lost Main/MickeyMouse cartoon. The cartoon, while seemingly just a loop of Mickey walking past some buildings for a few minutes, is found by a Disney executive to be much darker than it originally seemed.

The story can be read [[ here]].

!! This creepypasta provides examples of:

* AlienGeometries: At first the scenery was just a standard WraparoundBackground, but during the part where there is murmuring in place of the music, the sidewalk starts going in different directions, defying Mickey's walking physics.
* ArtStyleDissonance: The first recreation, which looked like it was made in MS Paint, and the third recreation, which looks like it was made in Flash. Note that the original story suggests that the original cartoon was made in the 30s.
* BlindIdiotTranslation: The Russian text in some recreations.
* DrivenToSuicide: The employee who watched the final portion of the cartoon, and in the third recreation, Mickey himself.
* DeathByAdaptation: While Mickey Mouse's fate in the original story and in most of the recreations is unclear, he kills himself in the third recreation.
* {{Defictionalization}}: The first recreation can be seen [[ here.]] The [[ second]] and [[ third]] are also available. A [[ fourth]] was recently released. It had different music than the others, and matched the picture on the creepypasta wiki, but only showed the first half of the short. Finally, someone took the forth one, which looked the closest to the "real thing", and [[ created his own version of the second half]], however, it's even less faithful to the story than the third one was. [[ This fifth one]] uses the same background loop as the fourth one, but uses a different (more crude) animation of Mickey. Unlike the fourth one though, it is complete, and is probably the most accurate complete version ever released thus far. Watch them at your own risk.
* DerangedAnimation: Floating ruins of buildings? Check. Sidewalks that defy perception? Check. Mickey continuing his walk cycle, but with a NightmareFace? Check.
* PragmaticAdaptation: The third recreation, where Mickey kills himself. Even more so recreation 4.5, which has images that seem to belong on a ShockSite in the second half of the short, and shows no distortion of the background or the ending mickey mouse face.
* MadnessMantra: According to the story, the poor employee who had to watch the last minute or so of the cartoon after Creator/LeonardMaltin couldn't handle any more of it stumbled out of the theater, pale and saying "Real suffering is not known" seven times.
* NightmareFace: [[ This image,]] [[UnreliableIllustrator despite having nothing to do with the story.]] The actual story gives us this description:
-->Mickey's face began to fall apart. his eyes rolled on the bottom of his chin like two marbles in a fishbowl, and his curled smile was pointing upward on the left side of his face.
* NothingIsScarier: The majority of the episode is just Mickey walking past buildings while odd noises play.
** The minutes where the cartoon briefly cuts to black with no sound also counts.
* RecursiveTranslation: Justified for the adaptions. The original story mentions a Russian sentence in the ending, but the Russian text was never spelled out; we only got to see the English translation "the sights of hell bring its viewers back in". Thus the adaptations have had to translate it back to Russian on their own.
* WorldOfChaos: The scenery eventually turns into this, with the buildings reduced to floating rubble and the sidewalk adopting AlienGeometries.
* WrapAroundBackground: At first, the background consists of just the same six buildings. But then everything gradually falls apart...
