I Have No Snout, and I Must Whinny

I Have No Snout, and I Must Whinny was a book written by obscure author Cesium Grande. Twilight Sparkle said it was a great book, but seemed to prefer the book about the apocalypse instead.

Behind the scenes
The name is a play on words of the famous short story and video game, I have No Mouth, and I Must Scream.
