Apparently this is now a thing over at a burger joint in Bangkok called Twenty Five Degrees. The new Rainbow Dash burger comes with a colored bun, a bottle of smooth pink milk, and two cupcakes. They have a limited run of it from the 9th to the 16th, so if you want to fly on over and try one, you don't have a lot of time to do it.
As for what kind of meat it is, they don't say. Probably not horse though?
Thanks to Squeaky Belle for the heads up.
