My Little Pony Rainbow Castle Cake

I did this cake for my daughters 5th birthday party. She wanted a My Little Pony party, so we did this cake and made up little goodie bags with pony stuff in them. This is the same cake I have done a few times before with different color combinations. I just love it so much, it's so simple, but you can tailor it to just about anything. It would be a beautiful wedding cake all done in white... Maybe someday! The cakes are 10 and 6 inches. The ponies I used are some I got off ebay. Everything is done in buttercream and royal icing except for the little flowers and the yellow shingles, they are fondant.
