Murderer Mouse (1930)

Another creepy cartoon created by the creator of Suicide Mouse (1931) and some of Magrolo Mouse (1929).
The cartoon begins with a title screen. At the top that says, in English, "Walt Disney Presents". In the centre, there is a circle with text saying "Murderer Mouse". After five seconds of this, it cuts to Mickey Mouse, who is seemingly joyful, walking out of his house with happy piano music in the background. However, the room he walks out of has a portrait of Minnie Mouse, but with a giant X over it. The cartoon looks worse than the beginning of Magrolo mouse, yet better than the other half. After three seconds, it switches to Mickey happily strolling on the streets (left), when he runs into a duck-looking character, crying. Its not Donald Duck, because Donald was created by Disney in 1934, whereas this was made in 1930. Anyway, Mickey asks the character "Are you OK?". The character replies "No". Mickey then says "I know what will make you happy". All three lines of dialogue are said in a Russian accent because the creator was Russian. However, the voices sound rather sad. When the conversation ends, Mickey walks in the opposite direction to earlier (right) and the duck follows him. This scene lasts for three seconds before they suddenly start walking backwards for another three seconds. The two then stop. The piano stops. Mickey turns to the duck. He gives him a creepy smile. He pulls out a knife. The screen cuts to black.
After ten seconds, the video cuts to... real world footage? Its just a room with a piano for three seconds, until someone dressed up as Mickey enters the room carrying a knife. The Mickey suit seems to be covered in blood. The man turns to the camera. A second later, the screen cuts to black for another ten seconds before switching to another room, with two other people lying dead on the floor, covered in blood. Thankfully, the screen only lasts one second, before cutting to black for another ten seconds. We then see a dog, still in real life, walking around. It looks like its struggling horribly. After ten seconds of this, the screen cuts to black, this time for five seconds, before turning back into a cartoon. It doesn't get any better, however, as we see Mickey eating up the guts of the duck and some other tall dog character, which isn't Pluto or Goofy. The sound, which wasn't there for the real world segment, is the same music box heard in Suicide Mouse, just less broken. It seems to be a Mickey Mouse March music box. The music box is accompanied with disgusting chewing noises. After twenty seconds, the screen cuts to black for one second, before text saying "PART 2 SOON" appears. After three seconds, the video ends.
OK, I have a theory for this. The creator of this video, who I will call Mr. Andreyev, is insane. Before he finished Magrolo Mouse, he worked as a group of three called "Andreyev Productions". They would make bootleg cartoons, usually of already-existing cartoons. They weren't well known, they seemingly did it for the entertainment. They worked on Magrolo Mouse, an original idea they had in mind. Mr. Andreyev had a wife and a dog. Somewhere in late 1929, Mr. Andreyev's wife cheated on him, hence the X on the Minnie portrait in Murderer Mouse. This made Mr. Andreyev go so mad, he killed his friends (in a Mickey suit) and recorded the suit and the dead bodies, presumably hiding both as he didn't get caught. He finished Magrolo Mouse afterwards. When he made Murderer Mouse in 1930, he included the recordings and a representation of the killing. There was also a recording of his dog, who was very poorly and on the verge of death. The dog died in 1930 or 1931. Mr. Andreyev was so depressed, he made Suicide Mouse (the part 2 of Murderer Mouse) and probably did exactly what Mickey did in said cartoon. Suicide Mouse (somehow) got exported to the US somewhere in the early 2000's. This doesn't explain the supernatural elements (the screeching and the impossible colours) and how the guard seeing the ending of Suicide Mouse repeated what the mouse did. Could it be Andreyev? We may just never know...
