Original Description:
 
The Rainbow Factory is one of my fav fanfictions plus Cupcakes.
 

 
 
Now a rainbow’s tale isn’t quite as nice  
As the story we knew of sugar and spice  
But a rainbow’s easy once you get to know it  
With the help of the magic of a pegasus device
 
Let’s delve deeper into rainbow philosophy  
Far beyond that of Cloudsdale’s mythology  
It’s easy to misjudge that floating city  
With it’s alluring decor and social psychology  
But with all great things comes a great responsibility  
That of Cloudsdale’s being weather stability  
How, you ask, are they up to the task  
To which the answer is in a simple facility
 
In the Rainbow Factory, where your fears and horrors come true  
In the Rainbow Factory, where not a single soul gets through  
In the Rainbow Factory, where your fears and horrors come true
