This was fun
Oh yeah, her hat is actually supposed to be like this rather than actually being a cake: [link]
and I were at Party City awhile ago and we found this crappy pink strawberry shortcake wig and put it on and just tried on every Pinkie Pie-ish hat we could find, and we thought the pink cake hat was the best.
If you want you can still consider it to be a real cake. Because that is highly amusing too. And she so would.
