Pinkamena 'Prism' Pie

This is for the Alternate cutie mark contest at . SO, STORY TIME!
Pinkamena kicked the pebble with her hoof a sighed. Today was the same as every other. Bland. Lifeless. Dull work with no end. Blinkamena and Inkamena labored on the other side of the farm as Pinkamena continued to diddle by the treeline, kicking stones and wondering about the outside..
BOOM!
Pinkamena's body vibrated as the world around her quaked. She looked up into the sky to see a dazzling rainbow wash over the sky, it's colors illuminating the shabby little farm like a spectral tide, filling her with happiness. She squeals and kicks happily, realizing her dream.
To make more rainbows, and make everyone as happy as her!
Basically, instead of partying, she wants to make rainbows! Though, since she isn't a pegasus, she has to use more organic methods, but the result is even more vibrant and beautiful!
Hope you like it!
