In a parallel universe..

[Justice]

This game is played by creating a parallel universe with one difference to this one. The next poster will then state the result due to the difference, and make his own universe.

Example:

Player 1: There is a parallel universe where people greet each other by smashing their heads together.

Player 2: As a result, humans are no longer able to function.
There is a parallel universe where men cannot speak.

I will start.
There is a parallel universe where the sky is bright purple.

As a result nobody knew when Smog started to fill the sky, the city soon ran in mayhem of poisoning.

The world's trees all had pink pretty leaves and bled red when cut.

The leaves also bleed when rotting after falling off of the trees, and now the world is completely flooded with leaf blood..

There is a parallel universe where people jump instead of walk
