This is the result of watching almost two hours worth of Flash tutorials.
It has no interesting plot, because it was just for practice.
If I have a good idea I'll animate but for now you can watch Pinkie Pie meaninglessly fly up into the air.
I downloaded the ponies from doublerainboom.com - I chose the simpler ones because I'm still learning Flash.
If it keeps playing again, right click it and uncheck "Loop".
