Over on DHN they've put up a post about a rumor-ish thing on Derpibooru of some MLP:FiM Burger King Toys that might appear some time this spring. If true, you can expect to find Twilight Sparkle, Fluttershy, and Pinkie Pie to appear in Burger Kings around March. For more details, check out the DHN post.
