This is the G4 Pinkie Pie cake I make for my fiance, Byron's ( ~Riku3322
) 21st birthday. He loved it.
It was a chocolate cake (which, by the way, is the only thing that should EVER be rubbed in a pony's face), decorated with vanilla frosting (Byron hates strawberry, had to food color it), sugar pearls, and the light-up necklace Pinkie Pie Party toy. Oh, and the box the toy came in. Had a bit too much fun tearing it up for additional parts XD.
If you can't tell, the design under the candles is her cutie mark
