It looks like Wal-Mart is starting to expand it’s cake selection for pony. While we have had the barnyard set for a while now, this cupcake pile, Applejack mini-cake, and the one in the 3rd image with the blue background appear to be new.
Real bronies sculpt their own giant Rainbow Dash cake models though. Don’t wuss out on me!
Thanks to Lonewolf for the cake images!
