My Little Pony Facebook page. It looks like the winner gets a free trip to San Diego Comic Con. Considering how fast the tickets sold out, this might be the only chance for some of us to get in to the event.
It looks like the submitter is really simple too:
Now go design some ponies! (And please avoid the black alicorns with red eyes, only Chrysalis can get away with that!)
And on a side note: It looks like the four ponies on the actual form are the Toys R' Us exclusive toy line characters. I still wonder if they will be including a robe and wizard hat for the Greatest and Most Powerful pony.
