Considering what's plastered across her flanks, putting Pinkie Pie in a game about balloons seems like a no-brainer. This game from Brian Bullock (which is listed as a beta, despite feeling quite complete) is basically a clone of the NES's Balloon Trip, but with ponies and an online scoreboard. The latter does wonders for replayability of the game, even if the mechanics of lower scores on a name overriding older, higher scores is a bit irritating. Regardless, the game is well-built for a clone game, and like the original, is a fantastic way to spend a few moments if you don't mind dying a lot.
