Yes, I know it's not a G4 MLP:FiM pony, but it's a bucking awesome place to start modding your own!
With all the great plushies out there, I'm sure somepony would be able to make a great custom skin for it and, from what I've seen from the figurine modders, there are many ponies out there with some skills at altering the general body shape of an item.
But wait, there's more!
The body can be altered to have full articulation (hell, even fully robot-icized, but that's a LOT more work and beyond my skills).
Hack the audio circuit and add a custom ROM with samples from characters on MLP:FiM and re-program the sensor triggers (The stock chip is likely potted, but most any PIC/Arduino/Propeller/other µC would likely be better anyway and giove a wider range of possibilities).
Forget BattleBots, build BattlePonies!

If Hasbro has kept this toy in production for the past five years, mayhap they would consider some MLP:FiM editions?
(last post for today, I promise.)
