Other MLP x South Park crossovers (comics of course!) I made:
Stan Writes A Letter To Princess Celestia: [link]
My Little Kenny: Dying is Magic (Season 1): [link]
"Dear Princess Celestia. Today I learned that I hate parties with ponies. Or scratch it. I knew that all along."
I had to draw South Park characters with outlines because they looked weird next to Pinkie - they would look good without outlines next to show-accurate ponies.
I used 3 vectors made by other people in panel 3 (due to being lazy):
Pinkie's Game by Omniferious [link]
Vector-phonograph by MisterAibo [link]
Slice of Cake by Vectorshy [link]
Everything else in this comic was drawn by me in Inkscape and Ponyscape (a derivative of Inkscape)
Rights to MLP and its characters belong to Hasbro.
South Park and its characters belong to Matt Stone and Trey Parker.
"Art" by me.
