The Day Diffusion Went Backward

Once upon a time there was a young lad named Goergiobobicus and he was sitting in school reading book called “The Day Diffusion Went Backwards” he was absolutely bored out of his mind. His teacher kept yelling at him because he was falling asleep every 2.3453529283 seconds. Then after he had fallen asleep again there was an alarm clock from the heavens, A.K.A the bell for school to let out. He jumped as if he was hopping a huge fence and he was out of the door before someone could say “OMG did you watch last night’s episode of Secret Life of an American Teenager”. He found himself on the bus playing with his Iphone all of a sudden there was a noise that sounded like a dump truck driving through a nitroglycerin plant. Then he realized that the noise came from his Iphone and a popup popped up. It said “would you like to install this brand spankin new app” so he clicked yes and it took a while then he finally scrolled to the app and it said “The day diffusion went backwards THE VIDEO GAME” and the he was just about to delete the app then he accidentally pressed play.
The game opened up and it didn’t look that bad because it had zombies in it, so he played the game. The game was more like a lesson or a story it explained how so many people we killed by zombies even though they had built a 53yd. concrete barbwire wall. The story went something like this.
Just a short time ago in a state really close to yours the city of Imabanana was under siege of zombies, these zombies were no regular zombies these zombies could hop 20 feet in the air and they had teeth the size of oversized watermelons. The zombies were coming in numbers by the 1,000,000,000,000,000,000,000,000,000,000,000,000,000 but the zombies could not get over the wall the humans had built. But the reason why 22,349,875,986,497,832 humans died is because of the stench that the zombies created, the thing is that the humans at the guard towers on top of the wall did not die even they were about 25 feet away from the zombies. They gaurds in the towers did not smell any of the stench that the zombies had created. I was said that that day was called T.D.D.W.B or the day diffusion went backwards. The stench had originated by the zombies but it was not noticeable, but by the time It got upto the people in the buildings that were about half a mile behind the towers and 3,789 feet above the guard towers it was 200% worse. It smelled like someone had killed a fish chopped its guts out, fed it to a bear with rabies, then chopped the bears head off and put it in sewer. It smelled quite foul no one knew how to stop it, so they all died.
