Fluttershy looks downright sleepy nestled in a ring of cherries and pretty pinkness. Lulled to sleep by the sugary sweetness and overwhelming excitement of a birthday party. I understand, pony. I've been there.
I like the age-old motif of hearts and keys. It never goes out of style and always seems so genuine and proper. I also like gags involving swallowing a key like in "Arrested Development" so with these cupcakes I'm all set.
