I got inspired by a series of YCHs created by CyonixCymatro which involved feral ponies in this sort of peeking pose. So I thought "Why not make an anthro version of that, since people seem to be warming up on Lacuna's changeling form on Discord?"

And yes, I did ask Cyonix permission to "steal" his idea. I couldn't find any publicly uploaded examples of his YCH on Derpibooru, but you can probably check out the profile picture of my friend ninjadeadbeard on FimFiction.
