From my tumblr:
Big Blueberry: Height: Big Macintosh Weight: Pleasantly Plump Info: Big Blueberry is an Ex-Royal Guard who was injured in the Changeling Invasion (Hence the Scar) he is a good, loyal friend who is nice to everypony he meets, but his sanity has (Rightly) been called into question on several occasions. (Seriously who is scared of Applejack?)
But he doesn’t ware one all the time. I told him to act natural in this picture….
In Blueberry’s world, yep.
