Oh, crap. The person I tweeted at actually put up your image a little bit before hand with a source link so I figured I didn't need to. Unfortunately there is no way to edit a tweet, but the shovel is a reference to a LostNarrator blooper where she said "Applebloom! Go get my shovel!" in Applejack's voice. It's sort of a meme. I can put out another tweet with the source in it if you want!
