Hasbro has not authorized an official My Little Pony: Friendship is Magic fan walk at SDCC, or a run, or any other type of group movement. And yet, when the doors open to SDCC in mid-July, you'd best get out of the way of the thousands of MLP fans who are going to want this more than anything they've ever wanted in their entire lives:
Hasbro's MLP SDCC exclusive, Derpy Hooves. If you don't know the story of Derpy Hooves -- well, consider yourself lucky, but if you need to know, just read this terrifyingly clinical Wikipage on the Derpy Hooves phenomenon on Know Your Meme. But all you really need to know is that Bronies will have no compunction about killing their own grandmothers for a shot at owning this figure. However, if you manage to get one (and live through SDCC), it might as well be made of solid gold for what you'll be able to sell for on eBay. Just sayin'.
