I think that by the time a girl is turning 16, she's done wishing for A PONY for her birthday, and perhaps slightly more interested in a somewhat more mechanical method of conveyance...but this pony, named Flibbertegibbette*, was present in the lower part of the birthday venue. It mostly seemed to really, really wish everyone would go away, which of course didn't stop Madison's friends from leaping into its pen and smothering it with unwanted kisses.
*I made that name up. It's probably actually named Dale Jr. or something.
