A full set of new mystery toys have been listed on Toywiz. judging by the description (found below), they appear to be some kind of ponified cupcakes, though I may be completely wrong there. Hopefully information pops up soon! Thanks to Zachary for the heads up.
"This cute, 3-inch tall collectible from Funko features a "frosting" lid that opens and allows you to store cupcake pieces inside. The My Little Pony Friendship is Magic Derpy Hooves Cupcake Keepsakes Series 1 Mini-Figure comes with a display pedestal so you can show her off at work, and you can actually take the mini-figure apart yourself as it's made up of removable accessories."
