All right, so I'm clearly onto something, seeing as how there's been a rainbow, one of the ponies' eyes flashed a rainbow, and they receive an item that also flashes a rainbow for three ponies so far. I can't say for sure if the items are the keys to the box, new Elements of Harmony, or something different altogether, but there's probably no doubt that they'll be important at or near the end of the season. Though, I think I have an idea of what might happen... I really hope this doesn't happen, but as I watched the rainbow pony commercial, I couldn't help but think to myself, "see? We don't need to change the show to apply to the toys. Twilight didn't need to become an alicorn!" And then it hit me. Flashing rainbows? Rainbow ponies? Could this be related? ...Oh, Celestia, PLEASE don't let it be related... I don't want the ponies to change anymore. Anyways, don't take my word for it, it's just a theory. Still, here's hoping it's wrong. I'd much rather have new Elements, or a way for Twilight to revert to being a unicorn.
